Fieldpiece SC680 Clamp Meter

SC680 is a wireless True RMS clamp meter with a rotating clamp head, designed for electrical diagnostics on HVAC/R equipment — air conditioners, heat pumps, and refrigeration systems. It measures AC/DC current up to 600 A, monitors voltage and power, checks phase sequence, and logs results in the Job Link system.

What it's used for

• Electrical diagnostics on HVAC/R equipment during installation and service
• Non-contact AC/DC current measurement with the clamp, up to 600 A, without breaking the circuit
• Simultaneous voltage and current monitoring on the dual display
• Inrush current measurement during motor and compressor start-up
• Phase sequence checking on three-phase installations
• Measurements on VFD-driven systems using the LPF filter
• Logging readings in the Job Link app

Key features

• Rotating clamp head — makes it easier to position the meter in tight service locations
• True RMS and LPF filter — provides more stable readings on non-sinusoidal waveforms and VFD circuits
• Power measurement — allows monitoring of the electrical load on the unit
• Job Link connectivity — enables saving and documenting readings in the mobile app
• Two Type-K thermocouple inputs — allow temperature measurement, e.g. supply and return air
