HM2305 5kv insulation resistance tester description video
Products features
- Designed to meet the following safety standards:
- IEC 61010-1,-2-30 (CAT III 600V/CAT IV 300V Pollution degree 2)
- IEC 61010-031 (Requirements for hand-held probes)
- With auto-discharge function
- When an insulation resistance like a capacitive load is measured, electric charges stored in capacitive circuits are automatically discharged after the measurement. Discharge can be checked on the voltage monitor.
- Backlight function to facilitate working at dimly illuminated location or at nighttime work.
- Bar graph display
- Audible and visible LIVE circuit warning
- With Auto-power off function
- The instrument automatically will turn itself off if there is no function change or button press for 10 min to conserve battery power.
- Auto-measurement and display of PI (Polarization Index), DAR(Dielectric Absorption Ratio)

Voltage monitor for insulation resistance range
****:30 – 6000V (resolution 10 V): ±10%rdg±20V
This monitor is used to check whether electric charges stored no the equipment under test are discharged or not. The voltage value measured and displayed on the LCD is a reference value. Please note that the indicated value, when an external AC voltage is applied to the instrument, is not a correct value.
