Fluke 343A repair
bastl_r:
Thankyou for your response.
Your problem is an other than mine, i think.
Your log was on the outputvoltage.
My measurment was directly on the referencespannung(TP2). The voltage at this point oscillates over long periods of time by around 20uV around the mean value of approx. 14.999670V.
Your Problem, i think, is the chopperamp. Maybe the ageing capacitors in it.
Regards bast_r
