Full accuracy maintained in harsh electrical environments
24 September 2010
GMC-I PROSyS, a subsidiary of Metrawatt International has introduced the CP41 AC/DC True RMS Clamp Meter, a hand-held unit that combines simplicity of operation and convenience with non-invasive measurement of current to an accuracy of ± 1% of reading and resolution of 1mA.

The meter’s range and sensitivity allow measurement of operating currents, and leakage currents, with a single product, and without breaking connections in the circuits under test. Measurement capability in the mA range permits verification of 4-20mA current-loops in process-control systems, while the meter is equally applicable to testing light-industrial and residential electrical installations.
The CP41 measures, selectably, DC or AC currents with a resolution of 1mA and, on its AC ranges, with true-RMS current indication. It maintains accuracy even in electrically noisy environments, featuring excellent rejection of external magnetic fields together with a very high level of immunity to interference from voltage transients.
The CP41’s design supports safe, single-handed operation in hazardous areas, assisted by a display-hold function which allows the user to take a measurement in a difficult-to-reach location, remove the CP41 from the test site, and to bring it back into clear view still displaying its current reading.
The CP41 and CP410 meet the safety requirements of EN61010-2-032:2002 and the EMC specifications of EN 61326-2-2:2006, and provide safe operation on uninsulated conductors carrying voltage of up to 300V with respect to ground.
