It's time for this fine Keithley to find a new home, as I got myself 2182A instead, and have already too many Keithley's.
I had
review this unit and used it occasionally for low-level measurements without any issues.
Well cared, well readable screen, no repairs, no dust inside or outside.
This is special -M version unit that have backup 9V power for input stage, not the standard 182. This is to allow input always at high impedance, even when meter is turned off.
Meter calibrated few months ago, versus fresh adjusted Fluke 5720A and calibrated Keithley 262 nanovolt-divider.
I can recalibrate prior to shipping and provide data report (no official accredited traceability though).
Also PTFE cable with special connector to copper spade-lugs is included. Just this cable alone is rare to get and may cost few hundred $.
Asking for
$1000 USD $900 USD + shipping (EMS, worldwide ~$100-150 USD).
Can also trade for other metrology-related goodies or instruments.
