True-RMS AC/DC Measurement

The Fluke 374 FC provides accurate True-RMS measurement for both AC and DC signals.

It can measure:


  • AC current: up to 600 A

  • DC current: up to 600 A

  • AC voltage: up to 1000 V

  • DC voltage: up to 1000 V

True-RMS technology allows more reliable measurements on non-linear electrical loads commonly found in modern industrial equipment.

iFlex Flexible Current Probe Compatibility

When combined with an optional iFlex flexible current probe, the Fluke 374 FC can measure AC current up to 2500 A.

The flexible probe design makes it easier to measure:


  • Large power cables

With wireless connectivity, technicians can:


  • View measurements remotely

  • Record measurement data

  • Save results to the Fluke Connect cloud system

  • Create reports directly from the field

  • Reduce the need to stand close to energized equipment

This function improves safety and productivity during electrical troubleshooting tasks.

Inrush Current Measurement

The Fluke 374 FC includes inrush current measurement for capturing the starting current of motors, transformers and other electrical equipment.

This helps technicians diagnose:


  • Motor starting problems

  • Circuit breaker issues

  • Power supply faults

  • Electrical load abnormalities

Additional Measurement Functions

  • DC voltage: up to 1000 V

Resistance Measurement


  • Range: up to 6000 Ω

  • Includes continuity detection

Capacitance Measurement


  • Range: up to 1000 μF

These functions allow the meter to be used as a complete troubleshooting instrument rather than a current-only clamp meter.
