Just got a Extech 845 , 1000 amp AC/DC clamp with a basic DMM on it and IR..
I used the DC amp once, it worked.. put the meter away, next day used it again. As soon as I select DC amps now, it shows a -32 Amp offset.
I can zero it however, It looks like the value its reporting is ~ 50% of the actual value.
I have not used this meter for nothing else yet, but I did plug in the test leads to check to make sure the rest of the meter worked after seeing this, and it seems to work ok on the other funtions..
Is anyone familiar with this failure ? The initial offset was only about +/- 0.5 amps if I remember..
