Hi...
I have an old KYORITSU K-200 FET VOM. I would like to align it the proper way. I have found the DC-cal and AC-cal. And those calibration isn't that hard to understand. But there is a cal called BIAS (VR 4). Is there someone who knows how to set the BIAS. I have set the BIAS-cal in mid position, and the instrument seems to work allright.

Best regards from SWEDEN

I searched a forum, that say that BK Precision had a licens to make a similar instrument like K-200. BK Precision called it "BK Precision Solid State 179 FET-VOM". Is there someone who has a Service Manual including a adjustment procedure?
I would appriciate if You couls share it with me.

Best regards
