Overview

DC resistance tester is a necessary testing item for semi-finished products, factory testing, installation, handover testing, and preventive testing of power transformers, transformers, reactors, operating mechanisms, etc. during manufacturing. Check the welding quality of the winding joints and whether there is a turn to turn short circuit in the winding. Check whether the voltage tap changer is in good contact at all positions and whether the actual position of the tap changer matches the indicated position. The instrument has the characteristics of small size, light weight, high output current, strong anti-interference ability, and complete protection function. The whole machine adopts ARM high integration core, which has automatic discharge and discharge alarm functions. Convenient instrument testing operation for rapid measurement of transformer direct resistance

IIINotes:

◆Connect the test clip. After connecting the test clip to the lead out end, twist the test clip a few times with force to cut through the oxide film to ensure a good connection.

If the contact end is exposed to air for a long time, the surface will be covered with an oxide film, which may cause unstable or inaccurate measurement results.

◆Before disconnecting, be sure to wait for the instrument to reset and there to be no current output. After the discharge is complete, turn off the power before disconnecting.

◆When selecting the current, refer to the range in the technical specifications column and do not use it beyond or below the range.
