Features:
Checking the insulation of high-voltage electrical equipment (electric motor, transformer, cable, etc.)
Use 50V-1000V voltage to test target insulation
It can measure up to 10GΩ resistance
Short current up to 1.8mA
Automatically calculates PI (Polarization Index) and DAR (Dielectric Absorption Ratio)
AC/DC voltage measurement and continuity test
Display backlight and auto power-off
When the input terminals are Hi and Lo, The overload protective voltage is 600V
