I am working on a Datron 1281 meter.
DC voltage calibration at 10v functions ok, but the Internal source calibration failed.
This One has errors after Internal source calibration.
Error codes:
2202 1Kv Range zero magnitude test (P028).
2192 100V Range zero magnitude test (P021).
2162 10V Range zero magnitude test (P006).
Is there anyone that has experience in repairing these instruments?
Thanks,
John
