I bought this broken
DATEL Voltage Calibrator DVC 8500 and just received it.
Starting this thread before I start the repair.
This seems to be a very nice little calibrator with good specs:
+/- 19.999 V
+/- 25ppm accuracy First thing to notice is a broken mains cable, it is like falling apart to dust.
May be I will upgrade it to a real mains connector.
I did find a nice Datasheet, even with calibration instructions, here:
http://www.calibratorsinc.com/images/DVC-8500_DATA_SHEET.pdfThe lever switches are moving with difficulties.
Does anyone here have experience with these lever switches.
I don't think they can be taken apart.
May be I can clean/grease them from the front, hmm ... will be interesting.
I first need to get a tiny torx to open it.
