MH12 digital megohmmeter insulated grounding resistance meter tester cable

Description: Insulation series digital tester adopts low loss and high ratio inductance energy storage DC voltage converter which can convert 12V voltage into 20V/100V/250V/500V/1000V DC voltage. It uses a digital LCR bridge for resistance measurement and insulation resistance testing. It has many advantages such as light weight wide measurement range backlight display test lock and so on. Advanced appearance stable performance and can also be used for electricity measurement. Based on the shoulder strap design it can be operated with two hands. It can be used in insulation resistance testing fields such as motors cables electromechanical equipment communication equipment and power facilities. Feature: LCD multiple display and analog bar display full symbol display automatic range software calibration full key operation. Material: ABS plastic Size: 172.7*140.3*62.3mm/6.8*5.5*2.5in Power supply: 8*AA batteries (not included) Maximum display: counts Measuring range: 1. Measure the output voltage MH12: 50V-1000V (50V 100V 250V 500V 1000V ). 2. Measure insulation resistance: MH12: 0.1MΩ-10GΩ. Absorption ratio and polarization index standard Absorption ratio DAR: The ratio of the insulation resistance value at 1 minute to the insulation resistance value at 30 seconds. Polarization index PI: The ratio of the insulation resistance value at 10 minutes to the insulation resistance value at 1 minute to judge whether the equipment has affected the insulation resistance due to moisture Insulating materials all have the absorption process and polarization process of charge after adding high voltage. The power system requires that the polarization index should be measured in the insulation test of the main transformer cable motor etc. and this data can be used to judge the quality of the insulation quality and aging problems.
