Voltlog #34 – Fluke 77 Teardown & Repair, Varistor Replacement
In this video I’m opening the Fluke 77 I scored at a recent auction to show and repair a small issue it has. One of the MOV (metal oxide varistor) in the input protection circuit had suffered damage probably while protecting the rest of the circuit when a HV signal was applied to it’s input, so I decided to replace the MOV.
The original MOV part number is V910LSX1399 specs: 910V 10% 1mA
The replacement MOV part number is Panasonic ERZV10D911 specs 910V 1mA
