Keithley 2400 SourceMeter review and teardown

<< < (4/24) > >>

TiN:
Seems this story have a happy ending after all :)

Got my unit calibrated by official Tek/Kei service.

Data before calibration
Data after calibration

So this will become a reference point/source from now on on my volt-nutting explorations.  :bullshit:

Btw, if anyone want - there is an broken 2400LV (no 200V range) poped up on bay recently: eBay auction: #201021188476.

robrenz:
Nice!  :-+

TiN:
Just got my bad boy back :)
Now have some reference point for volt-nut practice.



TiN:
2400LV for 750$ with faulty output :)

TiN:
Yey, Keithley still cares about 20 year old models...

New firmware released recently, in case someone with 2400 series SMU from Japan need it.
Why Japan?

Release notes:

Version C33 fixes the issue of powering up with a low line-voltage (90 volts in Japan) for models 2420, 2425, 2430, 2440. Upgrading to this version of firmware will add a 5-second delay to power-up for all models running it.

Models affected: 2400, 2400-C, 2410, 2410-C, 2420, 2420-C, 2425, 2425-C, 2430, 2430-C, 2440, 2440-C
Symptom: The instrument will power up, but the digital circuitry will not work properly. Therefore, there is voltage on the output and no readings are accurate.
Resolution: The issue has been corrected.
Enhancements: There were no enhancements included in this release.

Remirrored it on on docsite, as usual, in case you don't want login into Keithley's site.
