Service information needed: Xitron 2000M calibrator

[D2236]

Hi,

My XITRON 2000 calibrator developed a problem after being in daily use for many years. The current output is stuck at about 20 mA and the voltages are only correct under 2 V. The maximum voltage output is about 2.3 V.

I have emailed Xitron/Vitrek to ask for any diagram or service information, but they never bothered to reply. Is there any member who can share any diagrams or service manual to facilitate repairing the unit?

All help would be greatly appreciated.

Thanks,

I found some old thread regarding this instrument and repair, but since the last post was older than 120 days, the warning message suggested creating a new topic.
