Martindale CM57 True RMS AC Clamp Meter

The Martindale CM57 True RMS AC Clamp Meter measures AC current from 0 to 600A with a resolution of 0.01A and accuracy of ±1.9% via its 25mm jaw clamp. Additionally, it is also capable of measuring AC/DC voltage from 0 to 600V, resistance from 0 to 6MΩ, frequency from 0 to 100kHz and capacitance from 0 to 600µF as well as performing continuity and diode testing.

Readings are shown on the Martindale CM57’s backlit digital display and the meter features a data hold function that can freeze the reading on screen. The function is selected using the simple dial and it is even possible to use the meter’s non-contact voltage indicator to check for live conductors before starting work.

The Martindale CM57 comes supplied with a carry case, batteries, instructions and a set of TL16 test leads. The clamp meter is safety rated as Cat III 600V and is designed to be ergonomic and robust.
