Martindale earth leakage clamps are designed to clamp around both live and neutral conductors to measure the difference between the flowing currents allowing the leakage value to be calculated.

The Martindale CM67 Earth Leakage Clamp has been designed as a high quality clamp meter that is ideal for identifying appliances or circuits which are causing RCDs to trip.

With a resolution down to 0.01mA and accuracy of up to 0.05mA, the Martindale CM67 can be counted on to take the right results. A Data Hold key is also included for fixing the display and a Min/Max key for measuring the minimum and maximum values.

This Martindale earth clamp meter can measure up to 600V AC, is autoranging, has a low pass filter (LPF) eliminating high frequencies and a Comparator, setting 1mA to 20mA, with a buzzer sound showing when an input is greater than the set value.

Martindale CM67 Earth Leakage Clamp Meter includes
• Two 1.5V (AA) batteries
• Carrying case
• Test leads
• Instruction manual
• Optional accessories: TL55 fused leads
