Fluke 179 problem measuring resistance
<< < (3/4) > >>
neskor:
Tried to measure voltage again this time with a real resistor in between, 2K4.
Voltages are 0.194V on resistance and 1.283V on the diode, but when I disconnect only the probe from 179 and connect again, I get no voltages, but if I turn off the 179 or move the switch back to the resistance I get again voltages.
floobydust:
What part number is on the protective clamps? Some old Fluke used diodes, others use select low leakage transistors. I would test them.

Check here:
neskor:
tested, they are all good

I can see there is a slight discoloration on the top of Fluke 642998 ASIC, maybe went south???
