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:
1. Powered by lithium battery or AC 220V, can contantly test more than 100 sets of transformers by once charging.
2. 6 gears output current, the max output current 10A, max output voltage 25V, can automatically choose current.
3. Wide measurement range, high accuracy, 500uΩ-50kΩ.
