So I have one of these in the workshop which I have been using for some years to test equipment under repair before returning to clients, the machine has been regularly calibrated without issue.
Just recently though I have found there is a timing issue with each test for instance test for electrical resistance (set to 5 seconds) is taking less than 2 seconds, an earth bond test (set for 5 seconds) again takes less than 2 seconds. The problem seems to vary and affects all of the instrument tests.
I have carried out a factory default settings reset and it has made no difference, I have yet to disassemble the machine so include a picture of the unit for reference, I have the full service manuals.
thanking anyone who may be able to offer advice in advance
