Zucca:
K2001M for $300 is a cool deal, but it is a lot of work. Checking a 7.5 is an adventure.

Analog board page 6, coordinate D6-7


I beg you on my knees to recap it, you are walking on thin ice. It does not surprise me you received a not working K2001.

Moreover, I propose replace shift registers 14094 and all analog switches (DG411/DG404/DG211). It is much faster than troubleshooting these failures.

Open a new thread in the repair section and post the result of a self test, see you there.

Thank you, both you and user edavid who ran the schematics through OCR and emailed it to me so I could search.  This helps.

I fully intend to recap as preventative maintenance while doing other repairs.

It occurs to me that this is not the right place to continue this.  I've made a proper post in the repair section of the forum if you'd like to join me there: https://www.eevblog.com/forum/repair/keithley-2001m-7-5-digit-multimeter-repair-(not-a-bad-capacitor-failure)/msg5844301/

It seems (at least in the Netherlands) that the Siglent SDG1062X is sold out.
I've got one from Welectron.
