Product introduction
Insulation testing is very important to ensure the quality of products and the safety of people and equipment in operation.
Before adding power to the system, the insulation test is used to verify that it is sound and can improve the performance of the system. Insulation test can find manufacturing process problems and equipment defects, which can not be found before the equipment fails. In the European Union, the test is mandatory, even for the smallest civilian systems.
Features
1.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);
2.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.
3.Backlight function to facilitate working at dimly illuminated location or at nighttime work.
4.Bar graph display;
5.Audible and visible LIVE circuit warning;
6.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.
7.Auto-measurement and display of PI (Polarization Index), DAR(Dielectric Absorption Ratio);

Voltage monitor for insulation resistance range
30 – 600V (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.
