Uni-T Digital Megger Meter Insulation Tester UT501A

UT500 series Digital Megger Meter or 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 the ground. UT500 series can measure insulation resistance, AC Voltage, low resistance, PI (Polarization Index), and DAR (Dielectric Absorption). These are ideal tools for ensuring transformers, generators, high-voltage motors, capacitors, cables, arresters, and other electrical equipment can operate safely and accurately.Models in UT500 series: UT501A, UT501B, UT502AUni-T Brand Digital Megger Meter Insulation Tester, Model: UT501ACertifications: CE, UKCA2000-count LCD, overload indication, backlightAC voltage measurement, auto power offAuto dischargeContinuous low resistance measurementContinuous measurements mode, red warning light, and buzzer functionPI and DAR measurement, auto resistivity calculationLow resistance returning to zero function to improve accuracySpecifications of UT501A Insulation Resistance TestersSpecificationsRangeUT501AUT501BUT502AInsulation resistance (Ω)Test voltages100V/250V/500V/1000V0%~10%0V/500V/1000V0%~10P0V/1000V/2500V0%~100V0MΩ~100MΩ±(3% 5)250V0MΩ~99.9MΩ±(3% 5)±(3% 5)100MΩ~5GΩ±(5% 5)±(5% 5)500V0MΩ~99.9MΩ±(3% 5)±(3% 5)±(3% 5)100MΩ~5GΩ±(5% 5)±(5% 5)±(5% 5)1000V0MΩ~99.9MΩ±(3% 5)±(3% 5)±(3% 5)100MΩ~5GΩ±(5% 5)±(5% 5)±(5% 5)2500V0MΩ~99.9MΩ±(3% 5)100MΩ~9.9GΩ±(5% 5)10GΩ~20GΩ±(10% 5)Load current50V (R=50kΩ) 1mA0%~10%0%~10%0%~100V (R=100kΩ) 1mA0%~10%0%~10%0%~10%0V (R=250kΩ) 1mA0%~10%0%~10%0%~10P0V (R=500kΩ) 1mA0%~10%0%~10%0%~1000V (R=1MΩ) 1mA0%~10%0%~10%0%~10%00V (R=1MΩ) 1mA0%~10%Short-circuit current<2mA<2mA<2mALow resistance (Ω)0.01Ω~200Ω (about 5.0V/>200mA）±(2% 3)±(2% 3)AC voltage (V)30V~750V±(2% 3)30V~600V±(2% 3)±(2% 3)Click for More Information
