Vanguard WRM-40

Manufacturer Vanguard
Model WRM-40                                                 

 

The WRM-40 is a microprocessor based low resistance ohmmeter. With 40 Amperes of test current, the WRM-40 can very quickly provide a stable resistance reading of any large transformer. Dual resistance-reading channels measure two winding resistances on the same test cycle. The WRM-40 ensures operator safety by automatically discharging the transformer core energy after each test.
