ZX-3125B Insulation Resistance Tester
Product introduction
ZX-3125B Insulation Resistance Tester uses insulation test to check the insulation of the test object to the ground or between adjacent conductors, which is of great significance to ensure product quality and personal and equipment safety in operation.
Before powering up 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 equipment failure. In the European Union, this test is mandatory, even for civil systems.
Features
1. The design conforms to international safety specifications:
IEC 61010-1,-2-030(CAT III 600V /CAT IV 300V pollution degree 2)
IEC 61010-031 (handheld probe Requirements Standard)
2. Automatic discharge function: when testing the insulation resistance of capacitive load, the charging charge will be released automatically after measurement. The discharge state can be confirmed in the voltage mode.
3. The backlight function is convenient for working in dark light or at night.
4. The bar graph shows the measurement results.
5. Live line warning signs and buzzer warnings.
6. Automatic shutdown function: in order to avoid battery waste caused by forgetting to shut down, the instrument will shut down automatically when there is no operation 10 minutes after the measurement.
7. Automatic measurement and PI measurement (polarization index measurement), Dar measurement (induced absorption ratio measurement).
