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. |

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. |
