JYM insulation resistance tester is used for on-site insulation resistance measurement. The instrument has built-in positive and negative bipolar high-voltage power supplies, with large output power and strong load capacity. It is suitable for insulation resistance measurement of samples with large capacitance, such as power transformers and cables.
Features:
● High-voltage insulation resistance tester, with 5 range: 500V, 1000V, 2500V, 5000V, 5000V, test up to 10TΩ.
● Strict accordance with the safety standards for design
● Insulation resistance range 10TΩ @ 10 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 4 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.
