Martindale CM69 AC TRMS Earth Leakage Clamp Meter


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 Martindale CM69 Comes Supplied With:

  • Martindale TL16 test leads
  • Soft carry case
  • Alkaline batteries 
  • All Martindale clamp meters come with a 2 year warranty.
 
CM69 Press Release


Product Press Release January 2016:

Now available from Martindale Electric – pioneers in electrical safety – is the new CM69 TRMS AC Leakage Clamp Meter, ideal for troubleshooting leakage currents where other clamps can’t, for example, for tracking down the causes of nuisance RCD tripping.

Featuring class leading low current performance with a resolution 0.001mA the new clamps makes it easy to accurately measure AC currents from less than 0.1mA right up to 60A. The CM69 features a unique jaw design which minimises the influence of adjacent current conductors enabling professionals to perform precise and reliable tests at very low currents.

One of the few testers on the market which uses True RMS measurement, the CM69 ensures that leakage currents can be identified and measured accurately even when due to harmonics. In addition the new design includes a switchable filter enabling repeatable periodic measurements at 50Hz for assessing insulation quality and deterioration without powering down the circuit

The advanced features and high resolution make the new clamp an essential live troubleshooting tool for all electricians enabling fast solutions to common problems from nuisance tripping of RCDs, through to identification of triplen neutral currents. The very low current capability means it can also be used to simplify appliance testing by measuring leakage currents through the earth conductor or by clamping around both live and neutral conductors to measure the differential leakage current.

The new compact clamp includes AC/DC voltage measurement, plus resistance and continuity functions meaning it can be used to replace other general purpose clamps as well as offering a high level of troubleshooting. A CATIV safety rating and rugged design ensures the CM69 can be used in the most demanding applications.

Competitively priced, the CM69 is a lightweight and simple to operate meter with a high contrast backlight display for use in areas where ambient lighting is poor.

The ever increasing use of power electronics in electrical equipment and lighting can result in higher leakage currents and harmonics, the CM69 is the perfect troubleshooting tool to diagnose related problems easily and quickly without having to power down the installation.
