Description
IST High Voltage Micro Ohm Meter
Usage
The IST series High voltage Micro Ohm Meter tester is suitable for measuring the resistance value of various insulating materials and the insulation resistance of transformers, motors, cables, and electrical equipment. The safety performance of the instrument complies with the international standard IEC61010-1: 2001.
Features
1.IST High voltage micro ohm meter with 5 range: 500V, 1000V, 2500V, 5000V, 10000V, 15000V,test up to 15TΩ, manual voltage regulation function.
2.Strict accordance with safety standards.
3.Insulation resistance range 15TΩ @ 15kV.
4.The short-circuit current can be adjusted up to 5mA (optional for 10mA).
5.Automatically display the polarization index (PI), the induced absorption ratio (DAR) test value, and test the leakage current and capacitance.
6.Excellent anti-interference performance, the instrument still guarantees the test accuracy when the interference current reaches 2mA.
7.Two power modes: used by a lithium-ion battery, its life up to 4 hours (10000V@100MΩ).
8.Insulation resistance simulation column.
9.Perfect protection function and equipped with the spare fuse blowing prompt function (alarm).
