The Fluke 378 True RMS Clamp Meter uses FieldSenseT technology to make faster, safer measurements without having to touch live wires. The clamp meter allows you to accurately measure voltage and current. Simply clip the black test lead to an electrical ground, place the jaws of the clamp around the conductor, and read the voltage and current readings on the display. Power quality indicator to tell you if the problem is with the power line or the connected device. The 378 Clamp Meter includes a unique power quality feature that automatically detects power quality problems. When measuring with FieldSense, the 378 detects and displays power quality problems related to current, voltage, power factor, or any combination of these. Now you can quickly determine if the problem is with the power line or the connected device. 3-phase measurements in quick and easy steps. 3-phase voltage and current measurements in three easy steps. Calculate all phase to ground and phase to phase values. Measure extremely high currents with the iFlex® current sensor. With the included flexible iFlex current sensor you can measure alternating currents up to 2500 A. Measurements with the iFlex current sensor are much easier in control cabinets with tightly packed cables and on conductors with large cross-sections. Easy to read and handle with the included accessories. The 378 clamp meter makes your work easier. Once the value measured with FieldSense has stabilized, the display changes color to green. During continuity testing, a bright green screen indicates continuity, so you can perform continuity tests even in loud ambient noise. The 378 clamp meter includes:.
