    Martindale CM55 AC Clamp Meter

    The Martindale CM55 AC Clamp Meter is a basic clamp meter that can measure AC current from 0 to 400A, AC/DC voltage from 0 to 600V and resistance from 0 to 400Ω as well as performing a continuity test. The movable jaws can clamp around conductors with a maximum diameter of ø25mm and all the readings are provided with a high degree of accuracy (±1.9% ± 3 for current) and excellent resolution (±0.01A for current).

    The measurement function is selected using the simple thumb dial and a trigger that opens and closes the sprung clamps. Readings are displayed on the digital LCD screen and it has a display hold function which freezes the reading on screen. The unit is supplied with TL16 test leads and a soft case and is rated as Cat III 600V.
