GM-5kV Adjustable High Voltage Insulation Resistance Digital Megohmmeter
GM-5kV High Voltage Digital Megohmmeter
Product Introduction :
GM-5kv adjustable high voltage digital megohm meter test voltage is high, output is strong, the measured object is often with power frequency leakage or induction of high voltage interference power, so for personal safety, the use of this instrument must first be connected to the safety grounding wire! GM-5kv adjustable high voltage digital Megohmmeter test instrument is designed and developed by GDZX to test the electrical insulation resistance characteristics of large high voltage transformers, motor appliances, remote power cables or buried cables under the strong interference of high voltage substation and power plant site. It can also be used in a wide range of electrical insulation resistance measurement.
Microcomputer control, menu operation, LCD display, stable performance
Suitable for measuring in strong electromagnetic interference environment.
Wider measuring range, several voltage output gears.
Output voltage is continuous and adjustable
Auto measure R15, R60, R600, auto calculate DAR, PI
