Levell TM3B Microvoltmeter Repair & Testing
I do some minor repairs and then testing of the accuracy of a Levell TM3B Microvoltmeter against my Datron 4700 calibrator.
0:00 - Intro.
1:27 - Opening the case.
2:07 - YUCK!
3:21 - Testing the crapacitors.
5:10 - Testing if the TM3B even works.
8:29 - Re-checking the caps after a bit of reforming time.
9:21 - Checking the TM3B on my Datron 4700 Calibrator.
I really appreciate the donations and support I get from my Patreon Supporters and YouTube Members, donations really do help me to make content for the channel and buy broken test gear, this hobby gets expensive !: https://defs.link/?u=fcb3a1
