Re: FG 502 Adjustment and Possible New Issue

Just had a quick read of the Theory of Operation and Calibrations setions of the manual.

R250 is to set the DC level of the triangle wave before it goes into the triangle to sine converter. It needs to be set with a distortion meter, so don't touch it for now.

The DC level at the output is set with R485 (DC Bal).
