PalmSens4 diagnostics

Follow these instructions if your PalmSens4 does not give expected measurement results.
The steps below describe;

  • how to verify the instrument using the internal dummy cell
  • how to verify the sensor cable using the external dummy cell

 

Measuring on internal dummy cell

Requirements:

  • PSTrace (for the latest version go to the menu in PSTrace: Help > Check for updates)
  • PSTrace data file: “LSV on internal Dummy.pssession”  
    This file is installed in the folder: “My Documents\PSData\Instrument Diagnostics\PalmSens4” with PSTrace 5.4 or newer.
    Or download here: LSV on internal Dummy
  • PalmSens4 connected via USB-C cable with disconnected cell cable.

Step 1: Start PSTrace and connect to the PalmSens4.

Step 2: Load the file “LSV on internal Dummy.pssession”  via the menu: Data > Load data file

Step 3: Change the measurement setting from “New” to “Overlay” (menu: Measurement > Overlay)

Step 4: Start the measurement and check if the measured curve is identical to the loaded curve.

If the measured curve overlays the loaded curve, the next part to check is the cable. If they show a clear difference, please save the data file and send it to support@palmsens.com . Please send any other information that might be relevant.

 

Measuring on external dummy cell

Requirements:

  • PSTrace (for the latest version go to the menu in PSTrace: Help > Check for updates)
  • PSTrace data file: “LSV on PSDummyCell.pssession” 
    This file is installed in the folder: “My Documents\PSData\Instrument Diagnostics\” with PSTrace 5.4 or newer.
    Or download here: LSV on PSDummyCell.
  • PalmSens4 connected via USB-C cable.
  • Standard PalmSens4 sensor cable.

Step 1: Connect the sensor cable croc clips to the CE, RE and WE_B pads of the PSDummy Cell:

Step 2: Run PSTrace and connect to the PalmSens4.

Step 3: Load the file “LSV on PSDummyCell.pssession”  via the menu: Data > Load data file
(If the plot is showing Charge on the Y axis; click the curve “LSV charge vs time” in the Legend at the right and click “Delete”.)

Step 4: Change the measurement setting from “New” to “Overlay” (menu: Measurement > Overlay)

Step 5: Start the measurement and check if the measured curve is identical to the loaded curve.

If the measured curve overlays the loaded curve, the cable connections should be fine. If they show a clear difference, please save the data file and send it to support@palmsens.com . Please send any other information that might be relevant.
