🔴 #813 Fluke 343A DC Voltage Calibrator Repair – Part 5


I repair a Fluke 343A DC Voltage Calibrator. My Fluke 343A (which is similar to the Fluke 341A) had a issue with instability and drifting, and also the 300V range never worked properly.

I had replaced most of the capacitors already a few years ago when I originally repaired the Fluke 343A.

I trace the 300VDC range fault, voltage drift fault, and finally fix the Fluke 343A.
