I understand what you mean now. im really now sure how to do this. I
would at least check to see if the voltage is right on the boards.
It takes alittle time to understand the calibration manual but its
basically putting the positive and negative probes (from the digital
volt meter) on certain places on circuit boards and comparing the
number read out on the DVM to the number on the calibration manual.
