Test Program

  
Multichannel Potentiostat/Galvanostat  WMPG series

 
One stop test condition creation/modification

 

Parameter mixed input system
Unlimited number of test steps
Control values are  voltage, current, power, load, rest, C-rate, current scan, voltage scan, conditioning potential, voltage step, current step, rest conditioning, Last I, Last V, OCV.OcvScan
Step flow are defined by next step, Loop and cycle
Cut-off conditions can be set by;
time, voltage, current, dV/dt, dI/dt, percentage capacity(FCC, FCD, LCC, LCD), cycle time, capacity, -dV, power, temperature, Aux voltage, Calc voltage, dT/dt, OCV
Data sampling condition by each step : time, dV/dt, dI/dt, dT/dt, dV2/dt
And/Or logic in cut-off condition setting

Simple Monitor

Real time display: time, voltage, current, channel status
channel status color display: charging, discharging, standby, idle, calibration
Always activated window(This widow does not hidden)
Can be located outside of main program window.

Detailed Monitor

displayed test data: status, running time, step number, cycle number,  step time, current range, current, voltage, capacity, power, energy, Aux V, Calc V, temp, cycle file name, data file name,  file size.
Detailed monitor type selection: All channels, running channels only, grouped channels
Activated character only for running channels.

Grouping

Classification/Grouping each channels by users purpose
Labeling each group by operator name, chemistries etc.
Group monitoring available by this setting.

Graphics

Multiple plot format

General graph
  
Plot overlay: Max. 10 plot
Universal Graphics: Any combination of X,Y,Y1 axis parameters
Automatic updating plot with reloading button for running channel data
Automatic/Manual scale and polarity selection for each axis
Cross hair pointer by mouse click/arrow key displays coordinate values
Mouse zooming
Text insertion on graph
Copy to Clipboard  for usage in other application software
Slope calculation
Grid On/Off and dot/line selection
ASCII file conversion of graph data only
Parameter change without reloading the data file
Data set On/Off: Data can be visible or invisible by selecting/ deselecting the data set.

Reporting

General data report
Cycle data report
Step data report
Capacity data report
Calibration data report
Test program report
Automatic documentation; running time,Test memo, operator name, weight, test I.D etc.

Calibration

4 points calibration for voltage and each current ranges
Check-out function with calibrated data for confirming accuracy
Calibrates a channel while other channels are running
To prevent mis-calibration, error warning displays when error happens.
Linear calibration for + & - polarity with one procedure
Store & Backup calibration data

Filing

Create Potentiostat/Galvanostat mode or potentiostat mode test program file(Dual mode)
ASCII file conversion(TAB,comma,space delimited) of general data, cycle data, capacity data and step data
Maximum file size: 2GB
 Split general data by cycle number
Max. Data file name: 15char + channel number(3digit)

Software UPS function

Function On/Off: User can turn on/off this mode
When UPS function is activated, any assignment on virtual control panel is memorized at closing the program.

Safety.

Double safety check: Automatically stop the test run if the voltage /current/ temperature exceed the hardware specification or saftey  limit setting value on test program
Fail function: If the measurement value is different from control value, the test is stopped by fail check function in order to protect the cell and/or system failure.
Each channel has its own fuse to protect over current or voltage
While any channel is running, operator could not close the server program
Automatic cell mount detection

Misc

 Closing function of all activated windows
 Dual time input mode(9999sec or hh:mm:ss)
 Independent server program
 English version & Korean version available
