[volt-nuts] Fluke 5100B Calibrator‏ Repair Help

[Tom Knox]

Someone will most likely have an exact value, but assuming that RV1 and RV2 are being used as excessive transient voltage protection another way to determine value is to use a variac to power up the 5100B and measure the normal voltages at RV1 and RV2. Then replace with a properly rated MOV.

> The capacitor support bracket fell into the power supply module and vaporized both varistors, RV1 and RV2. A call to Fluke tells me they no longer can supply these MOV's. According to the manual's parts list these varistors are in-house parts by Fluke. I have no way of determining a substitute part. Is there anyone that can help me identify what could be a useful replacement?
