Functional characteristics
1. There are a variety of voltage output 2500V/5000V/10000V measuring resistance range of 0 ~ 400GΩ
2. The two methods display the insulation resistance simultaneously. The analog pointer is used to easily observe the variation range of insulation resistance, and the bar chart shows the measurement results.
3. It adopts 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. The operation interface is friendly, the various measurement results have the power failure prevention function, and the measurement results can be stored continuously for 19 times.
5. When the instrument produces high voltage, there is a prompt sound output and corresponding display, with automatic voltage release function.
6. Built-in residual high voltage discharge circuit, after the test can automatically discharge the residual high voltage on the tested equipment.
Seven. Dual-use AC/DC, rechargeable battery and AC adapter.
8. Automatic shutdown function: If no operation is performed 15 minutes after the end of the measurement, it will automatically shut down. After the automatic shutdown, press the ON/OFF key for 1 second before it can be turned on.
9. USB interface data transmission, high voltage prompt and red warning light, 18 groups of data storage function.
10. The meter has a portable design and a backlight function for easy work in dark light and easy field operation.
11. High voltage short circuit current ≥3mA, it is a test instrument for measuring insulation resistance of large transformers, transformers, generators, high voltage motors, power capacitors, power cables, arresters and so on.
