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 Selected specifications Clamp current range up to 600 A AC/DC Safety category CAT IV 600 V / CAT III 1000 V Display dual, backlit Temperature inputs 2 × Type-K thermocouple Selected functions Inrush, phase sequence, LPF, capacitance, frequency, µA DC, continuity, diode test In the box SC680 clamp meter Molex RCT2 test leads ADLS2 silicone test leads ASA2 alligator clip leads 2 × ATB1 Type-K thermocouple 2 × Velcro straps 9 V alkaline battery ANC7 protective case User manual
