• Product Description

    The CM69 is a new 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 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.

    Peak hold, a switchable low pass filter and TRMS measurement make the CM69 ideal for many applications:

    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

    The CM69 also features auto ranging and a high contrast backlit display.

    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 displayed. Alternatively clamping around the earth conductor will also display the earth leakage current.

    The CM69 is supplied with Martindale TL16 test leads, soft carry case, alkaline batteries and manual. All Martindale clamp meters come with a 2 year warranty.
