1. Overview The Insulation Resistance Tester is designed with brand-new design and combination of massive integrated and digital circuits; it can measure insulation resistance, AC voltage, etc. and enjoys high degree of accuracy, stable performance, easy operation and reliability. It is used for insulation resistance measurement for insulation materials and various kinds of electric equipment such as transformer, electric machines, cables, switches, electrical appliances, a ideal tool for electric equipment maintenance, testing and inspection.
Safety Symbols 2 The instrument has double insulation or reinforced insulation. AC Voltage Ground Comply with European Union standards 3. Technical Specification Accuracy ±(a% reading+digits); calibration per year. Ambient Temperature (23±5)°C Environmental Humidity 45% to 75% Insulation Resistance Measurement Rated Voltage 100V 250V 500V...
1. Turn the function knob to select one of test voltages 100V/250V/500V/1000V. (1) Before testing insulation resistance, the circuit under test must be completely discharged and completely isolated from power supply circuit. (2) Insert the red test wire into the “ LINE” input port and the black test wire into the “EARTH” input port. (3) Connect the red and black alligator clip to the circuit under test.
