Huazheng HZJY-5K-I Factory Insulation Resistance Tester

An insulation resistance tester, also known as a megger, is a simple and commonly used direct-reading instrument for measuring high resistance. It is generally used to measure the insulation resistance of circuits, motor windings, cables, electrical equipment, etc. Its measurement unit is MΩ.
Megameters often use hand-cranked DC generators to provide power, typically offering 250V, 500V, 1000V, 2500V, and other types. The three most commonly used types in engineering are 500V, 1000V, and 2500V. Megameters also use transistor DC converters instead of hand-cranked generators to provide high-voltage power.

I. Features

High-voltage insulation resistance tester, with 5 range: 500V, 1000V, 2500V, 5000V, test up to 5TΩ.

● Strict accordance with the safety standards for design

● Insulation resistance range 5TΩ @ 5 kv

● Short circuit current can be adjusted, maximum 5 mA (Can be ordered as high as 10 ma, short circuit current products).

● Automatic display polarization index (PI), induced electric absorption test values than (DAR), and can test the leakage current and capacitance.

● Anti-jamming performance is superior, the interference current reaches 2 mA, still ensure accuracy of test instruments.

● Capacitive discharge rapidly, cable test, no need manual discharge, instruments and automatic discharge quickly.

● 2 methods for power: use of lithium ion batteries, battery life can be up to 6 hours (5000V @ 100MΩ).

● Insulation resistance simulation column.

● Digital filtering functions, external influence deviation display value causing mitigation point using filter function.

● Perfect protection function, and the spare fuse prompt functions.
