The E94 clamp is an ammeter clamp which employs a Hall effect cell which allows the measurement of direct or alternating current without intervention on the installation (no interruption of the current to be measured).

The main qualities of this pliers are:
- Compactness and ergonomic shape to reach difficult access points.
- Sensitivity of the measurement.
- Simple and safe use.

The E94 clamp allows you to measure currents from 100 mA to 100 A peak with 2 ranges 10 A and 100 A. The bandwidth ranges from continuous to 100 kHz (-3 dB).

It owns:
- "DC zero" by button whose parameters are saved,
- indicators:
. overflow,
. of a zero DC validation statute

Its specificity: the output signal cable has a 4-point overmolded connector, compatible with the latest generation Chauvin Arnoux Class A Qualistars.
The gripper is then powered by the tool.
The specific connector allows an automatic feedback of the clamp by means of the instrument.
