(Type: UONT100A)
This Test Set is capable to measure low resistance like switch contacts, breaker contacts, busbar splices, joints, fuses, low inductive windings etc. by circulating high value of D.C. through the contact/junction and measuring D.C voltage drop (4 terminal method) which, sent to instrument amplifiers , thereby being displayed on resistance meter.
