DIGITAL PRESS FAQ

Research evaluation equipment that applies axial force while managing load, position and temperature. A separate electrochemical analyzer measures the cell's electrical response.

Contact between solid electrodes and solid electrolytes can affect resistance and polarization. Compare pressure, temperature and loading history as well as material composition.

Its main purpose is to compare cell responses under defined mechanical conditions, linking actual load, position and temperature to electrochemical results.

The press manages load, position and temperature. The external analyzer measures voltage, current and impedance. Keep the data sources and units distinct.

No. EIS requires a separate electrochemical analyzer. The four-terminal connection connects the analyzer to the sample; it is not an impedance analyzer.

No. It evaluates performance under defined conditions and does not guarantee improvement for every material.

Electrical responses and mechanical histories provide clues, but do not establish the cause automatically. Structural, surface or imaging analysis may be needed.

Record the sample and conditions, set loading and temperature steps, verify stabilization, then perform electrochemical measurements. Preserve the mechanical history and electrical results under a common test ID.

Compare pellet resistance and contact response under different loading conditions. Do not attribute changes in total resistance to intrinsic conductivity unless bulk and contact contributions are separated.

Yes. Compare treated and untreated interfaces under matched cell configurations and pressure conditions, including whether performance is retained at lower pressures.

The equipment can support studies relating pressure to polarization, impedance and indications of short circuits. Confirm jig, atmosphere and electrical compatibility first.

Compare pressure-dependent responses for different compositions, particle sizes and forming conditions. Record electrode geometry and manufacturing history.

Compare performance across pressure steps to evaluate low-pressure operation for a particular cell. There is no single optimum pressure for all materials.

Use a condition matrix that changes one main factor at a time while recording actual load and temperature. Verify both thermal and mechanical stabilization.

Manage storage, transfer and assembly atmospheres and exposure history with moisture sensitivity in mind. Sealed-jig and inert-atmosphere suitability must be confirmed for each configuration.

Structural, chemical or imaging analysis may be necessary to establish the cause of interface changes. Link complementary results using the sample ID.

The general manual mentions TPU-001, TPU-010 and TPU-040; the communication manual mentions TPU-040B. Common descriptions do not establish identical specifications across models.

Confirm functional differences in the final specification for the actual model, including options and software compatibility.

Check the quotation and delivery configuration for included items and quantities, including jigs, electrodes, cables and software.

Their appearance in a system diagram does not establish inclusion. Check the quotation, order and delivery documents for models, licenses and installation scope.

Documented functions do not establish standard inclusion. RS485/Trigger is marked as optional; other functions also require model-specific confirmation.

Confirm approved parts and replacement criteria for the particular model and operating conditions.

Not necessarily. Terminals and displays may differ by production date and options. Check the nameplate, terminals, delivered software and approved cables.

The nameplate, model-specific specification, quotation, packing list and installation acceptance records. Also verify jig and cable part numbers, licenses and software versions.

The supplied specification states 270 × 350 × 280 mm. Confirm whether connector protrusions are included and allow additional cable, motion, cooling and service clearance.

The supplied specification states 24 kg. Confirm included accessories, total installed load and center of gravity using delivery documents.

The specification lists Al / SUS / Bakelite. This does not establish the material, finish or chemical and thermal rating of every sample-contact part.

The supplied specification states 220 VAC, 6 A, 50–60 Hz, single phase. Check the actual nameplate, cable, protective earth and circuit requirements.

No. Verify cable routing, moving-part clearance, heat dissipation and maintenance access for the actual configuration.

The documents advise avoiding outdoor use, vibration, corrosive gases and excessive electrical noise. Confirm permitted conditions in the applicable manual.

Confirm the manufacturer's transport instructions and whether the handle is approved for lifting before moving the equipment.

Confirm supported operating systems, runtime, drivers, permissions and ports for the delivered software version.

The general specification lists normal force of 0–4,000 kgf. This is document- and model-specific; confirm the actual equipment, jig and sample limits.

The general specification states 0–4,000 kgf, while RUN/SET descriptions state 10–4,000 kgf. Confirm whether the 0–10 kgf region is supported and validated.

The general specification lists normal-force resolution below 1 kgf. Confirm the applicable model and distinguish resolution from accuracy.

No. Its reference basis and applicable range are unclear, so it cannot be extended to guaranteed system accuracy.

The general specification describes manual and PID control and a pressure-mode designation. Confirm the actual model and implementation.

SV is the target load; PV is the currently measured or displayed load. Check the actual trend rather than assuming target attainment.

Target attainment and load stability during measurement must be checked separately.

The documents do not define one universal tolerance for all samples. Define acceptance criteria in the test plan.

kgf is a unit of force. MPa is a unit of pressure, meaning force per unit area.

Average pressure is P = F/A. Use consistent units and state the area definition.

Assuming uniform force transfer over the circular area, average pressure is approximately 12.73 MPa.

No. Different effective loading areas produce different average pressures at the same force.

Use the area defined for the force-transfer model and state that choice explicitly.

No. It gives average pressure over the defined area and does not directly determine the local stress distribution.

Record manufacturing or forming pressure separately from the operating pressure maintained during measurement.

Recording both paths is useful when studying reversibility and path dependence.

The specification lists 30 mm travel. Confirm the actual configuration.

The supplied specification lists distance resolution below 1 μm. Resolution is not a statement of sample-thickness accuracy.

Not necessarily. Actuator travel and available sample mounting height are different constraints.

Not without calibration and correction. Equipment position is not automatically the absolute sample thickness.

Define the reference before testing, such as after mounting, contact detection or target-load attainment.

The document describes showing or hiding an absolute-distance graph referenced to the origin, rather than resetting the origin.

It is described as setting a return location to reduce unnecessary travel to the origin after stopping. Confirm the actual return behavior.

No. Time-dependent sample or jig deformation is possible, but position alone does not establish the cause.

The general specification states room temperature to 80 °C. Confirm the model-specific specification and options.

It describes the resolution of the temperature indication or controller, not guaranteed sample-temperature accuracy.

No. Controller illustrations do not establish equipment cooling capability or permissible operating temperatures.

PV is the reading at the sensor location. It cannot automatically be treated as the internal sample temperature.

Target attainment and thermal equilibrium of the sample and jig must be verified separately.

No. The additional 10 minutes described is a particular high-temperature ceramic/jig application example, not a universal rule.

Yes. Thermal expansion of the sample, jig and frame, and material changes, can influence both.

It switches the convection fan on or off. Follow the approved cooling procedure when deciding when to turn it off.

The door, LCD, FAN, temperature controller, RUN/STOP, CONTROL, POWER and status indicators.

The general manual shows a four-terminal connection, optional RS485/Trigger, USB and mains input. Check the delivered unit.

WE, WE_ref, CE and CE_ref distinguish current-carrying and voltage-sensing connections. Use the approved analyzer and jig wiring diagram.

No. Four terminals do not mean four independent measurement channels.

Photos and common descriptions do not establish compatibility or supply of jigs for every cell format.

Do not assume compatibility from connector appearance. Verify the interface standard and approved wiring.

Connect measurement leads according to the approved analyzer and jig diagram. Measurement wiring and protective earth serve different purposes.

Front/rear photos and functional diagrams are available, but detailed wire-numbered and pin-numbered diagrams have not been confirmed.

Use cable identification, approved wiring tables, continuity and insulation criteria, ratings and reference-load acceptance records.

The supplied documents describe standalone operation using the front CONTROL knob, RUN/STOP and temperature controller.

Check the moving-part envelope, jig interference, power and cables, and the state of connected external equipment.

After the startup screen, the loading mechanism moves upward and normal force is initialized. Confirm behavior for the delivered model.

The supplied general manual calls for at least one hour after power-on for rated accuracy. Follow the applicable model documentation.

Rotation changes menu selections or numbers. Pressing selects items or switches editing states.

PV is the currently measured or displayed value. SV is the user-defined target value.

Stopped alone does not establish zero residual load, room temperature or safe access. Follow the model-specific procedure.

Confirm interlock presence and operation in the safety documents for the installed model.

The document describes pressing the knob from the Stopped screen to enter Set Load.

Apply the value with Save and Exit, then check the final SV on the main screen.

The described sequence uses RUN/STOP to start and displays Running. This does not by itself prove target attainment or stabilization.

The document describes target adjustment using the knob while Running. Confirm increments and application behavior, then reassess stabilization.

The menu is shown, but the controlled object, directions and continuous or step behavior are not fully established.

Speed choices are illustrated, but numerical mm/min values and applicable movement phases are not confirmed.

No. Tare zeros the measurement indication; it does not release physical load or stored elastic energy.

No. Zero setting does not replace sensitivity, linearity or repeatability verification, or a calibration certificate.

Record the test ID, execution time, reference state, PV before and after zeroing, warm-up status and temperature.

The documented basic sequence is SET, adjust with the arrow keys, then SET again. Verify the actual controller, units and allowed range.

No. Check the final SV. The supplied description mentions returning to the operating screen after 30 seconds without a key press.

The supplied descriptions contain both durations. Verify the actual controller and its approved instructions rather than assuming one universal duration.

No. Stopping control does not establish immediate cooling or safe touch conditions. Check residual heat and follow the approved cooling sequence.

The general overview describes that sequence, but it is not a universal test procedure. Define the order for the sample and jig and verify mechanical and thermal stabilization.

No. A procedure specific to the model and jig is required, including orientation, alignment, fastening, insulation, permitted conditions and access criteria.

Separately verify temperature-control and press stop states, residual load, return position, cooling, external measurement and file saving.

A normal RUN/STOP control must not be treated as equivalent to a safety-circuit emergency stop. Verify the installed equipment's emergency procedure and safety circuit.

Check the cause and mechanical, thermal and electrical state, and follow an approved recovery procedure before restarting.

Main, Data Viewer and Setup, with equipment status, graphs, load, temperature and file-management areas. Screen examples are not measured acceptance results.

The supplied software description includes time-series graphs for these variables. Confirm the delivered version.

The document describes Load SET, temperature SET and temperature Run/Stop. Confirm the supported model and software configuration.

The described software controls file recording separately using Start and Stop. Check saving status independently.

Open Data Folder is described as showing the storage location. Verify the actual path and saved files.

It loads files, replots graphs and adjusts X- and Y-axis ranges.

The document describes clearing the displayed graph. Do not interpret it as file deletion; verify actual files and saving state.

The document describes selecting and saving the serial port in Setup. Confirm drivers and serial settings in the installation documentation.

A CSV path appears in an example, but the complete version-specific format, columns, units and timestamps are not established. Inspect actual exported files.

It saves data at regular intervals; the documented default is one second. This is not automatically the sensor acquisition or control-response period.

It is described as saving when the current value differs from the previous value. Confirm thresholds, timing and whether transients can be missed.

These statements may describe different stages. Sensor acquisition, PC reception, display updates and file saving are not established as identical periods.

They concern physical response, data transfer and file recording respectively. Faster saving does not automatically mean faster sensing or precise synchronization.

In an approved preliminary check, compare command times, PV changes and saved timestamps. Record timing gaps, delays and failure behavior.

File timestamps alone do not establish command or measurement times. Use equipment logs and common events, preserving any correction and its basis.

The press provides mechanical and thermal conditions. BioLogic and EC-Lab apply electrical excitation and acquire voltage, current and impedance.

The documented setup includes a control PC, EC-Lab, CellTesterTCPclient/server, the press, jig, sample and BioLogic analyzer. Verify models, channels, cables and software versions.

EXTAPP launches the client, which relays press commands through the server. The communication manual describes RS232 to the press; verify the installed path.

The server handles equipment communication and is described as remaining running while EC-Lab invokes the client. Confirm reconnect and duplicate-instance behavior.

Confirm analyzer, channel, firmware, EC-Lab and client/server compatibility before purchase or integration.

No. The name alone does not establish remote-network or multi-device support. Verify the approved architecture and concurrent-control scope.

No. Check analyzer channels, polarity, cables, correction and electrode contact independently.

Integration and analysis are separate functions. Confirm analysis support for the actual configuration and preserve test IDs, measurement intervals and analysis settings.

It places execution of an external program into the technique sequence. In the described setup it launches the client and passes commands as parameters.

The communication document specifies the CellTesterTCPclient path. Confirm the delivered filename, location, version and permissions, and that the server is running.

It prevents progression until the external application exits. Application completion does not itself establish sample load or temperature stabilization.

No. They operate at different levels. Confirm the installed command's target, completion and timeout behavior separately.

Verify actual load, temperature and position stabilization separately, using the test plan's criteria.

No. Spaces, colons, order and parameter syntax can affect execution. Verify the installed manual and actual responses; do not execute unverified strings.

Repeat condition command, actual PV check, stabilization assessment, EIS and file linkage for each condition. Set values and waits within approved sample and jig limits.

It is described as setting target load and starting operation. Confirm units, range, W behavior and completion criteria for the installed version, then check actual PV.

SET is described as setting target load only; RUN sets the load and starts operation. Confirm when values apply and the resulting operating state.

The documents describe motor-control stop after target attainment but also use immediate-pause wording. Confirm timing and behavior; load can change after motor stop.

It is described as ending press operation, releasing load and returning to an initial state. Verify the model-specific motion sequence and safe access conditions.

The document describes motor stop after a specified time following target attainment and hardware storage of the setting. Syntax and zero-reset instructions require installed-version verification.

It sets target temperature. The command description states room temperature +10 to 80 °C, differing from the general room-temperature-to-80 °C specification. Confirm actual permissible conditions.

RTM is described for temperature-control start/stop, but RTN and differing colon formats also appear. Use the verified command table for the installed version.

Under manufacturer-approved conditions, separately verify commands, actual responses, sequence and final state, including PV, Wait behavior and saving. This is not a cell-performance test.

Change pressure in steps at a fixed temperature and verify actual state and stabilization criteria at every step.

Keep actual load, geometry definitions, measurement criteria and resistance interpretation consistent at each temperature.

A test can place EIS within cycling or rest periods and link actual conditions to cycle numbers.

To separate individual effects, use a condition matrix changing one main factor at a time.

Check the DC state and assumptions of linearity and time stability as well as the spectrum.

For EIS, record frequency range, amplitude, DC conditions and time. For cycling, record current density, voltage window, capacity basis and rest periods.

Yes. Maximum previous pressure, cumulative hold time and the loading, unloading, heating and cooling paths can affect the state.

Yes. Lead, holder and cable resistance, inductance and parasitic capacitance can affect the response.

It reduces parasitic impedance associated with a particular wiring and holder configuration. Use an applicable validated procedure.

No. It does not automatically remove resistance at interfaces inside the sample.

Too small an amplitude can increase noise sensitivity; too large an amplitude can cause nonlinear response.

Review time drift in spectral shape and representative resistance, OCV, and load and temperature histories.

Evaluate possible noise reduction together with whether the intended mechanical and thermal conditions remain maintained.

No. It supports spectral consistency assessment but does not guarantee a correct equivalent circuit or physical assignment.

No. Confirm those ranges using the external analyzer and the applicable wiring and jig configuration.

Sequential execution does not establish precise time synchronization between separate instrument datasets.

Use common events such as loading start, an actual-state change or measurement start to evaluate offsets.

Report EIS start and end times and the range of actual conditions across that interval.

No. Without a continuous log, intermediate fluctuations are unknown and maintained load cannot be claimed as verified.

Document any interpolation of short gaps and do not interpolate across abrupt events. Preserve the original data.

Use a common test ID linking the sample, conditions, technique, measurement order and version.

No. Also retain native instrument files, unmodified logs and technique files.

The common convention is Z′ horizontally and −Z″ vertically, in Ω. Confirm the actual plotting convention.

Use the same axis ranges and aspect ratio and show frequency direction and measurement conditions.

Only for a fully observed ideal single-RC semicircle can the difference between intercepts be read as that resistance.

Yes. Frequency-dependent impedance magnitude and phase help assess overlapping processes and frequency-range limitations.

First compare within their common frequency window and preserve all original data.

Also examine the original Ω data and the definitions of area and thickness.

It is a 25% resistance reduction relative to the original value.

Report the observed shape and chosen resistance change first. Treat the proposed cause as an interpretation requiring additional evidence.

Start with the simplest physically plausible candidate consistent with cell structure, electrodes, geometry and expected time constants.

Physical assignments require additional evidence, such as thickness, area, temperature or electrode-dependence studies.

Except when n = 1, Q should not simply be reported as capacitance in F.

No. Shape alone does not justify automatically selecting an infinite Warburg element.

Record circuit connectivity and element names, data range and exclusions, initial values, bounds, fixed values, weighting and software version.

Use documented evidence and predefined exclusion criteria. Do not delete points from the original data.

Also examine frequency-dependent real and imaginary residuals and parameter reliability.

First establish that identically named resistances represent the same physical process.

For a uniform through-thickness current path, σ = L/(R_cond × A_elec). State the resistance and geometry definitions.

Use thickness L in cm, area A in cm² and resistance R in Ω.

Choose the resistance corresponding to the intended bulk, total-electrolyte or apparent response, and state the interpretation.

Assuming uniform current and that circular area, approximately 1.019 mS/cm.

No. Resistance and conductivity change rates are not equal, and thickness and area may also change.

If initial geometry is used, disclose the assumption and report apparent conductivity referenced to the initial geometry.

ASR is interface resistance multiplied by electrical area, with units Ω·cm². It is not conductivity.

Consider thickness, resistance and area inputs, temperature, and model-selection effects.

Convert temperature to K and specify whether the model uses ln σ or ln(σT).

The document proposes four levels: directly verified, corrected estimate, initial geometry, and insufficient evidence.

First verify that it measures actual electrode separation and establish the complete measurement path.

Use a measurement model separating sample, jig, contact and thermal contributions and their errors.

A block of known stiffness can assess system deformation under the same contact arrangement and pressure/temperature path.

No. Recovered and in-load thickness are not interchangeable.

Distinguish mechanical loading area, geometric electrode area, microscopic contact area and effective current-carrying area.

Inferring area from the same resistance and using it to recalculate conductivity can create circular reasoning.

Consider raw-data completeness, mechanical and thermal stability, electrical plausibility, circuit justification and geometry evidence together.

Valid data meet the defined purpose. Conditional use limits the result to particular metrics or ranges. Remeasurement is needed after the cause is addressed.

No. A result must not be removed solely because it differs from expectations.

If the original data allow recovery, reanalysis is possible with a documented correction history.

Limit the causal hypothesis and changed factors to make the source of the problem easier to assess.

No. Preserve and link the original test, revised analysis and remeasurement under the same test record.

No. Resolution differs from accuracy, repeatability and calibration status. Supporting records and conditions are required.

Repeated EIS tests short-term acquisition repeatability; reassembly includes mounting/contact variation; independent samples also include manufacturing variation.

There are three independent samples and nine spectra. Report those counts separately.

Choose replicate counts and acceptance criteria according to manufacturing, assembly and day-to-day variability and the target uncertainty.

First determine each sample's representative value and within-sample spread, then assess variation between independent samples.

CV = 100s/mean and is unsuitable for metrics with means close to zero. Check assumptions before reporting statistical intervals.

Use a paired design, calculating each sample's difference or ratio before combining results.

If irreversible pressure effects are expected, use a common loading path or deliberately separate path groups.

Include sample, condition, spectrum and replicate IDs; actual pressure, temperature and path; fitting settings; geometry; results, uncertainty and assessment.

Include load, position and temperature histories with EIS intervals, Nyquist and Bode plots on consistent axes, and fitting residuals.

State the measured change first, then separate possible mechanisms and the additional evidence needed to establish them.

Verify units, signs and rounding; force versus pressure; conductivity versus ASR; and independent sample count versus spectrum count.

No. Filename and cover dates may differ, and the revision relationship between communication manuals V1 and V2 may be unclear.

No. Illustrative calculations are neither equipment performance guarantees nor actual cell-test results.

Technical explanations, review templates and proposed test designs must be distinguished from implemented software functions.

Separately check the running server, client path, COM/RS232 connection, command string and press state.

Check EXTAPP Wait, client exit behavior and the technique sequence.

First separate electrical wiring, contact, channel, shielding, correction, technique settings and sample-state issues.

Check saved settings, operating state, sample, jig and errors, then follow approved criteria for target-not-reached conditions.

Confirm recovery and restart behavior using the installed model's approved procedures.

Use the manufacturer's maintenance instructions for the applicable model and operating conditions.

Confirm the applicable quotation, contract and warranty document.

Prepare shape, diameter or length/width, thickness, layer structure, electrode area and materials.

Separate forming and operating pressure, state the area definition, and give target temperature ranges, paths and hold times.

Provide analyzer model and channel, EC-Lab version and intended techniques such as EIS, cycling or OCV.

Prioritize the intended outcome, such as pressure-dependent contact resistance, conductivity, low-pressure performance, temperature dependence or cycle life.

Suitability must be assessed against sample geometry and the jig's mechanical, electrical, thermal and environmental conditions.

It is useful to agree native files, press logs, analysis settings, graphs and report formats before testing.

Discuss the required configuration and installation environment during quotation review. Scope and schedule are confirmed individually.

Actual results must be verified together with the equipment model, test conditions and raw data. Illustrations alone are insufficient.

No. It is a technical reference. Actual operation requires the applicable model's operating manual.

Confirm their applicability using the revision history for the equipment and software versions.

Functions are described, but individual sensor models, ratings, locations and the complete measurement path are not established by the available information.

Confirm the presence and operating scope of each protection function for the installed model.

Use manufacturer documents matching the equipment, firmware and integration-software versions.

No. An optional terminal label alone does not establish trigger specifications or precise time-synchronization support.

Acceptance must follow the delivered specification and site-specific agreed criteria, including environment, power, communication, jig, wiring, reference tests, safety and calibration records.
