    2. OPERATION 2.1. MEASUREMENT PRINCIPLE The MA114 sensor is based on the Rogowski coil principle. This provides: very good linearity and no saturation effect (and therefore no overheating) wide measurement dynamic, up to several kA insensitivity to DC (measurement of the AC component of any AC + DC...
  • Page 9 To optimize measurement, center the conductor in the coil. Set the switch to the range providing the best sensitivity and ensure the red OL indicator is off. (OL indicates saturation of the electronics, resulting in a measurement error.) AC Current Probe Model MA114...

  • Page 10: Disconnecting The Ma114

    While this feature is activated, the orange Auto Power Off indicator is lit. To override automatic power off: With the MA114 OFF, press and hold down the Auto Power Off button while turning the sensor ON by turning the switch to any measurement setting.
