AC VOLTAGE MEASUREMENT, AUTO POWER Off . AUTO DISCHARGE . CONTINUOUS LOW RESISTANCE MEASUREMENT . CONTINUOUS MEASUREMENTS MODE, RED WARNING LIGHT AND BUZZER FUNCTION . PI AND DAR MEASUREMENT, AUTO RESISTIVITY CALCULATION . LOW RESISTANCE RETURNING TO ZERO FUNCTION TO IMPROVE ACCURACY UT502A INSULATION TESTERS ARE USED TO MEASURE THE INSULATION RESISTANCE OF ELECTRICAL EQUIPMENT AND HOUSEHOLD APPLIANCES. THIS IS DONE BY MEASURING THE INSULATION RESISTANCE BETWEEN ELECTRICAL CIRCUITS OR BETWEEN CIRCUITS AND GROUND. UT502A CAN MEASURE INSULATION RESISTANCE, AC VOLTAGE, LOW RESISTANCE, PI (POLARIZATION INDEX) AND DAR (DIELECTRIC ABSORPTION). THESE ARE DIEAL TOOLS FOR ENSURING TRANSFORMERS, GENERA-TORS, HIGH VOLTAGE MOTORS, CAPACITORS, CABLES, ARRESTERS AND OTHER ELECTRICAL EQUIPMENT THAT CAN OPRATE IN A SAFE AND ACCURATE MANNER.
