Martindale CM67 Earth Leakage Clamp Meter - MARCM67
The Martindale CM67 earth leakage clamp meter with resolution down to 0.01mA and a basic accuracy of 0.05mA. Ideal for identifying appliances or nuisance circuits which are causing RCD's to trip.
The CM67 has a comparison feature allows values between 1mA and 20mA to be set and the meter will beep if it measures above the pre set comparison level. This triggering allows you to identify the time of high leakage currents and so helps identify the offending equipment.
Earth leakage clamps operate by clamping around both the live and neutral conductors and measuring the difference between the currents flowing, allowing the “leakage value” to be calculated. The CM67 Clamp Meter also has a hold feature which helps when being used in awkward places. A low pass filter eliminates frequency's above 150Hz avoiding false readings.
