Earth Leakage Clamp Meter
A very high quality earth leakage clamp meter with resolution down to 0.01mA and an accuracy of up to 0.05mA. Ideal for identifying appliances or circuits which are causing RCDs to trip.
The comparison feature allows values between 1mA and 20mA to be set and the meter will beep above this 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.
Alternatively clamping around the earth conductor will also display the earth leakage current.
