Martindale CM69 TRMS AC Earth Leakage Clampmeter
CM69 is a high performance TRMS AC Leakage clamp meter with outstanding low current capability. The pocket sized clamp also measures AC-DC voltage and resistance. 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 clamps operate by clamping around both the live and neutral conductors. They also measure the difference between the currents flowing, allowing the "leakage value" to be displayed. Alternatively clamping around the earth conductor displays the earth leakage current.
