A range offering unprecedented analytical and diagnostic functions!

TRMS version of Min and Max: The Min and Max are TRMS values calculated over a duration of up to 100 ms. This feature is particularly useful for sizing an installation, the diameter of a power cable, a thermal protection device, etc.

Peak+ and Peak-: Calculated over a period of 1 ms, the Peak+ and Peak- values help to characterize the distortion affecting the signal measured. For example, they may reveal variations in the installation's behavior or even malfunctions.

ΔREL, for quick evaluation: Comparison with a reference quantity is a quick way of evaluating and analyzing your results. A signal's variations can be measured differentially or relatively. The first method indicates the difference between the value of reference and the value measured. The second method indicates the proportion. The ΔRELfunction can be applied to any type of measurement and can be used jointly with the Min, Max and Peak functions

Feature rich clamp-on meter

Ideal tool for any work in the field and is simple to use and groups all the necessary functions in a single, compact solution. Leveraging cutting-edge technology, this meter guarantees top-notch quality while ensuring user-friendly simplicity.

Performance

Benefit from a fast 12-bit TRMS digital acquisition system offering high measurement accuracy. Thanks to it's large bandwidth and high crest factor, this clamp provides accurate measurements whatever the signal type.

Ergonomics

The entire range is designed for one-handed use, even when wearing safety gloves. For maximum efficiency, each measurement corresponds to a specific switch position. The one key, one function concept makes it even easier to use. In addition, this clamp is equipped with automatic detection of the type of signal (AC or DC) on currents, voltages, and power values.

True InRush® function

True InRush® function provides the unique ability to measure power-up events from devices on a network that is already energized. Unlike other instruments which only measure the inrush when the installation is first powered up, our power clamp-on meters measure all types of inrush, even those due to load increases on an installation which is already up and running.
