hello Folks

Keithley 5 1/2 digit dmm having a problem

any hint or schematics available?

thanks in advance
Kleinstein:
The Keithley 2110 is supposedly the same or very similar to picotest 3510/3511. There may be some service manual available from that side. However don't expect schematics.
squadchannel:
2110 is M3510A. There is no service manual available.

2100 = M3500A, is available. It may be helpful.
Kleinstein:
The M3500A service manual is of very limited use. That meter is closely related to the K2000. The M3510 / K2110 are build around a SD ADC chip and because of the lower voltage range of the ADC also a different front end and amplification.

What are the problems of the meter ? Depending on the faults one may be able to narrow the problem down to a part of the meter.
Some faults can also be detected from a careful optical inspection of the suspect area.
If nothing helps a crude reverse engeniering of the relevant part could be possible - usually there are not that many custom parts.
