Performance characteristics:
1. There are a variety of voltage output options 250V/500V/1000V/2500V/5000V
2. The insulation resistance value is displayed simultaneously in two ways. The use of analog pointers can easily observe the variation range of insulation resistance, and the use of word display can accurately obtain the measurement results.
3. Use embedded industrial single-chip microcomputer and real-time operating software system. High degree of automation, strong anti-interference ability, the instrument can automatically calculate the absorption ratio and polarization index without manual intervention.
4. Friendly operation interface, various measurement results have anti-power-down function, and 19 measurement results can be stored continuously.
5. When the instrument generates high voltage, there will be a prompt sound output and corresponding display.
6. Built-in residual high voltage discharge circuit, which can automatically release the residual high voltage on the device under test after the test.
7. Both AC and DC, equipped with rechargeable battery and AC adapter.
8. The instrument adopts portable design, which is convenient for field operation.
9. High-voltage short-circuit current ≥3.5mA. It is an ideal testing instrument for measuring the insulation resistance of large transformers, transformers, generators, high-voltage motors, power capacitors, power cables, lightning arresters, etc.
