Data sheet


The F407 clamp is used low-voltage, medium-power systems in LV electricity production and distribution, industry, railways, etc. It is also suitable for lift/elevator technicians and other lifting and transport equipment specialists.

Maintenance, testing, monitoring, diagnostics and connection are the main applications for the clamps in this series.

Equipped with a fast 12-bit TRMS digital acquisition system, F407 clamps offer particularly accurate measurements. Due to their large bandwidth and high crest factor, these clamps guarantee accurate measurements whatever the type of signal.

Automatic AC/DC detection is a standard feature on all the models in this range, as is IP54 protection.

The large backlit 10,000-count display makes it easy to read in all circumstances. The fact that each rotary-switch position corresponds to a single function means that it is simple to use.
