UT501A

UT501A Insulation Resistance Tester UT500 series 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. 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, power capacitors, power cables, arresters, and other electrical equipment that can be operated in a safe and accurate manner.   Applications: It can be used for insulation resistance measurement for insulation materials and various kinds of electric equipment such as transformers, electric machines, cables, switches, electrical appliances; an ideal tool for electric maintenance, testing, and inspection.   Features: 2000 count LCD display, overload indication, backlight AC voltage measurement, auto power off Auto discharge Continuous measurements mode, red warning light and buzzer function   Complies with: CE, RoHS,      Technical Data & Features Specifications   Range UT501A Insulation resistance (Ω) Test voltages 100V/250V/500V/1000V 0%~10% 100V 0MΩ~100MΩ ±(3%+5) 250V 0MΩ~99.9MΩ ±(3%+5) 100MΩ~5GΩ ±(5%+5) 500V 0MΩ~99.9MΩ ±(3%+5) 100MΩ~5GΩ ±(5%+5) 1000V 0MΩ~99.9MΩ ±(3%+5) 100MΩ~5GΩ ±(5%+5) Load current 50V (R=50kΩ) 1mA 0%~10%  100V (R=100kΩ) 1mA 0%~10%  250V (R=250kΩ) 1mA 0%~10%  500V (R=500kΩ) 1mA 0%~10%  1000V (R=1MΩ) 1mA 0%~10%  Short-circuit current
