Insulation Resistance TesterZC-430

ZC-430 series Insulation Resistance Tester, also known as megohm meter, insulation resistance tester, for insulation resistance testing. This instrument is a high performance digital type instrument, with LCD large screen with backlight display, data hold, automatic discharge, automatic shutdown and other functions. The instrument has the functions of test timing and voltage monitoring. When the loop voltage is higher than 36V, the instrument will forbid tested to protect the safety of the tested objects and personnel. The instrument easy to operation, insulation resistance value, test time and output voltage display with the same screen, also have the test functions of dielectric absorption ratio test (DAR), polarization index test（PI), AC voltage testing. This series instrument maximum output voltage 5000V, the biggest test resistance value 400GΩ, maximum short-circuit current 2mA.
