A while ago I bought a Fluke 83 on ebay, and I thought it was perfect however I have noticed recently that it does not measure capacitances in the manual measurement mode when "nF" is selected. I tried to measure 100 nF and 5,6 nF. It displays "0L". However it does do measurements in the uF ranges and the auto mode.
Is this is a common type of failure? What can be the cause of it? Thank you in advance.
