Voltage and current measurements with FieldSenseT. The Fluke 377 FC True RMS clamp meter uses FieldSenseT technology to make faster, safer measurements without touching live wires. The clamp meter allows you to measure voltages and currents accurately. Simply clamp the black test lead to an electrical ground point, place the jaws of the clamp around the conductor, and read the voltage and current readings on the display. 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. View on your smartphone and store in the cloud via Fluke Connect software. Determine phase rotation and display in Fluke Connect software. No more handwritten notes and complicated manual calculations. Measure extremely high AC currents with the iFlex® current sensor. With the included iFlex flexible 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 377 FC clamp meter makes your work easier. As soon as the value measured with FieldSense has stabilized, the color of the display changes to green. During continuity testing, a bright green screen indicates the presence of continuity, so you can perform continuity tests even in loud ambient noise. The 377 FC clamp meter includes:. Fluke 377 FC true-rms current clamp meter. Flexible iFlex current sensor (48 cm). Silicone-insulated test leads TL224 . Adjustable test probes TP175. Ground clamp AC285 (black, 1 piece). Magnetic hanging device TPAK ToolPakT (23 cm) . Carrying case. Quick start guide. Use Fluke Connect® software to record, analyze, and share test results with your team. Fluke Connect software lets you remotely log, monitor, and trend test results to identify intermittent faults. Fluke Connect also lets you collect data to form the basis of a preventative maintenance program.
