Withstand Voltage Tester

Product Description

This intelligent DC low resistance tester is an instrument for testing various types of DC resistance such as transformers, motors, switches, relays, connectors, etc. The instrument has the advantages of wide measurement range, high accuracy and fast speed. The instrument uses a high-precision constant current to flow through the tested piece and five-terminal measurement to effectively deduct the lead error, which is suitable for users to make high-precision measurements; at the same time, the instrument has added a sorting function, and the user can directly set the upper and lower limits of the resistance or the percentage error for sorting, which greatly improves the test speed of similar products. The measuring end must not input the mains voltage. The design of the instrument complies with the provisions of the technical standards GB/T10193 and GJB1782. It meets the manufacturer's requirements for efficient and accurate testing.

This withstand voltage tester is designed according to the requirements of JJG795-2016 "Withstand voltage tester verification regulations". Its maximum test voltage is AC5kV: current is 20mA. 0-5kV is continuously adjustable. It can meet the safety test of Class 1 and Class II electrical appliances.
