🔴 Datron 4700 Calibrator Repair Part 2 – No. 826


I continue the repair of my Datron 4700 calibrator.

The Datron 4700 is very similar to the Datron 4705, Datron 4708, as well as the Datron 4200A and Datron 4000.

I keep looking to identify the units problems, I find the cause of the shorted supply rail and fix it, and then start diagnosing the output voltage faults, and check all of the power supply rails.

This is Part 2, there are more videos about the repairs so check out the playlist and subscribe to make sure you don’t miss them when they are released.
