Fluke 393FC, 377FC and 378FC clamp meters

Fluke has released a variety of clamp meters, for non-invasive and safe AC and DC measurement.

The Fluke 393FC clamp meter is compliant with CAT III 1500 V and designed for use in environments where high DC voltages are present, such as photovoltaic systems, solar power systems, railway industry or testing batteries in server rooms. The clamp meter can measure voltage up to 1500 V DC, 1000 V AC and current up to 999.9 A DC or AC; using the attached iFlex AC flexible probe, users can measure currents up to 2500 A. The meter also offers True RMS measurement and enables the measurement of resistance, capacitance, frequency and inrush current.

The included test leads meet the CAT III 1500 V DC safety category. The meter is IP54 rated, which makes it suitable for use in harsh environments such as outdoors. The clamp jaw is 25% thinner than that of the Fluke 37X series, which allows users to take measurements even in hard-to-reach places. The built-in Fluke Connect technology makes it possible to save measurement results and upload them to the cloud or to mobile devices.

The Fluke 377FC and 378FC clamp meters are meanwhile powered by the company’s FieldSense technology, which allows users to measure simultaneously voltage and current on insulated wires. Simply connect the black test lead to any earth ground, then clamp the jaw around the conductor; the meter display will show the measurement of AC current, DC current (up to 999.9 A) and AC voltage (up to 1000 V). The devices feature the True RMS measurement function and additionally enable users to measure frequency, inrush current or resistance.

The 378FC features automatic detection of power supply quality problems. When taking measurements using FieldSense, the device will alert users to problems with voltage, current or the power factor. With this function, the user can quickly learn whether the problem lies in the power supply line or in the device itself. The 377FC and 378FC clamp meters, like the 393FC model, support Fluke Connect technology.
