LV True RMS Insulation Resistance Tester 505A

True RMS Insulation Resistance Tester

505A is a true RMS handheld insulation resistance tester with combined features of a digital multimeter and insulation tester. These testers can measure AC/DC voltage, frequency, resistance, capacitance, continuity, insulation resistance, PI, DAR, and automatically calculate resistance ratio to determine the insulation status. 505A can be used in insulation resistance testing of precision tool, including motors, cable, transformers, switches, electrical appliances, and insulated materials.
