The Martindale CM69 is a high performance TRMS AC Leakage Clamp meter with outstanding low current capability able to resolve down to 1µA. This pocket sized clamp also measures AC/DC voltage and resistance. The CM69 is ideal for troubleshooting leakage currents including tracking down the causes of nuisance RCD tripping.

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. The CM69 is capable of accurate AC current measurement from 0.1mA right up to 60A with a resolution of 0.001mA in the 6mA range.

FEATURES

True RMS measurement.
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.
Low pass filter and peak hold.
Shielded jaw for high repeatability.
Auto power off & low battery indicator.
Display backlight.
