Cell Connections – Fuses in the Cell Cable
50
Testing For Open Fuses
A Gamry Framework test checks for blown fuses without having you remove the fuses. A simple Potentiostatic
test is run on the Calibration Cell with the Gamry UDC4 Dummy Cell. The test is run using the “Set a
Voltage.exp” script in the Framework’s Utilities Package.
Connect the cell leads to the Calibration side of the UDC4. You do not need to place the UDC4 within a
Faraday cage. Select the command

on the Framework’s menu bar. A
dialog box similar to this appears:

Enter a
Voltage
of 1 V as shown above, then click the
OK
button. The Framework opens a runner window, and
a graph of current versus time appears.

We expect you to see one of two very different results:
If the instrument is working properly and the fuses in the cable are good, the measured current will be
around 500 µA as seen above. No overloads are seen.
