The Martindale CM69 is a high performance true RMS AC earth leakage clamp meter with an outstanding low current capability allowing it to resolve down to 1µA. The advanced jaw design minimises the influence of conductor position and shields against external fields from other conductors to give more accurate and consistent results.

Earth leakage clamp meters operate by clamping around both the live and neutral conductors and measuring the difference between the currents flowing, allowing the 'leakage value' to be displayed. Alternatively clamping around the earth conductor will display the earth leakage current.

The CM69 is also capable of accurate AC current measurement from 0.1mA right up to 60A with a resolution of 0.001mA in the 6mA range. The pocket sized clamp meter also measures AC voltage, DC voltage and resistance.

Peak hold, a switchable low-pass filter and True RMS measurements make the CM69 ideal for many applications including:

  • Troubleshooting of RCD nuisance tripping
  • Periodic measurement of leakage current at 50Hz to check for insulation deterioration
  • Accurate measurement of triplen neutral currents and other distorted waveforms
  • Differential current measurement for appliance testing
