Different Offset front and rear Panel inputs

Post by DavidLester » February 8th, 2015, 8:49 pm

My 2015 meter has a different offset when using the front jacks 5-6mV and varying while the rear panel is +/- 200nV and relatively stable.
I am moving the same set of test leads from front to rear, so the difference is internal to the meter.
Are there any suggestions on how to easily resolve the issue or is a repair needed?

This is one of the differences between comp cal and mfg cal.
Mfg cal adjusts the rear zero..
If front zero is only being done then this could be why the difference.
