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 is ~5
mA as seen above. No overloads are seen.
•
If the one or both fuses are open, all the current readings are near zero, and a red CA Overload
indication may be seen at the bottom of the runner window.
If this test indicates an open fuse, use the procedures described above to check both fuses. This test cannot tell
which fuse is blown. Both fuses can blow simultaneously.
If the fuse test indicates an open fuse, and the fuses both check out a good with an ohmmeter, some other
problem has occurred in the cables or the instrument. Contact Technical Support at Gamry Instruments as soon
as possible.
