The tester can be used to test:
Sensitive objects: transformer, mutual inductor, reactor, etc;
Resistive objects: conductive wire, switch contact, copper bar, etc.
The DC resistance test of transformer winding is an indispensable test item after transformer is transferred, overhauled and changed. It adopts new power technology, with stable performance, quick measurement, compact size, easy to use, high precision of measurement and good repeatability of data. It is the ideal equipment to measure the DC resistance of transformer windings and high power inductance devices.
Product Features:
