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

  
  

• Strong load capacity, short-circuit current about 5mA.

  
  

• Measuring range up to 0 ~ 10TΩ, auto switching range.

  
  

• The analog bar pointer & digital display, clear and accurate

  
  

• Test time display at any time, buzzer beeps every 15 seconds

  
  

• Auto discharge high voltage within 30 seconds after test

  
  

• Auto measure ambient temperature, air humidity, date and time.

  
  

• Storage capacity up to 60 records, data may not be lost for 20 years.

  
  

• RS232 serial interface

  
  

• Built-in Micro-printer

  
  

• Auto remind power off when no operation for 5 minutes

  
  

• Perfect protection, high reliability
