Description
Overview
GAOTek digital insulation resistance meter also known as megohmmeter, high voltage insulation resistance tester, etc., for the insulation resistance test. The instrument has a large LCD screen grey backlit display, data storage, data access, alarm, automatic shutdown and other functions. At the same time, it also has the function of measuring DC voltage, AC voltage, absorption ratio and polarization index of DC voltage. It is suitable for measuring the resistance value of various insulating materials and the insulation resistance of transformers, motors, cables and electrical equipment. At the same time, it can output a variety of different voltage levels with the step-adjusting voltage function.
Features
- Microcomputer control, menu operation, stable LCD display
- Strong anti-interference for challenging electromagnetic environments
- Seven voltage output options, adjustable from 0 V
- Automatic measurement of R15, R60, R600 with absorption ratio
- Displays leakage current, absorption capacitance simultaneously
- Range 0 tΩ to 10 tΩ, automatic range switching, measures current and capacitance
