Description

The Sonel CMP-402 measures AC current, AC and DC voltage and more. The meter provides precise measurements downstream of frequency converters. The device is versatile due to many measurement options. Darkness in the workplace is not a problem thanks to the built-in flashlight.

Modern clamp

The innovative shape means easier access in hard to reach and tight places. The clamp edging is equipped with a contactless voltage indicator sensor.

Visibility in any conditions

Darkness in the workplace is not a problem thanks to the built-in flashlight.

Multifunctional

The device is versatile due to many measurement options. In addition to the basic measurements, the instrument has special functions, including inrush current (INRUSH), max / min peak values (Peak MAX/Peak MIN), relative value (REL).

Robust design

With the help of the latest technologies, a compact instrument for working in the toughest conditions has been created. The rubber housing protects the device against accidental damage.

Measurement of converters

The meter provides precise measurements downstream of frequency converters thanks to the VFD function.
