Meatest M109R High Resistance Decade

Mechanic high resistance decade with RS232 remote control for voltages up to 5 kV. Internal battery for up to 3 hours of on site calibration.

  • 12 GΩ and 5 kVdc limits
  • Voltage limit indication
  • Battery-powered
  • Remote control via RS232 bus
Categories: ,


M109R High Resistance Decade is designed for calibration of insulation meters and megaohmmeters and resistance ranges of safety testers, HIPOT testers or any other DC high resistance meter with test voltage up to 5 kV. Maximum voltage rating is indicated on front panel to ensure safety in operation. Internal rechargeable battery for up to 3 hours of grid-independent operation is standard part of delivery.


Even though the M109R looks mechanical, internal resistance standards are switched electronically by relays. This way we could fit it with RS232 remote control so it can be used in Caliber or any other automated calibration solution.


DC resistance 1 MΩ – 12 GΩ, 5 kV max.
