Whether you're working on small circuitry in mini-split or on large commercial units, the new SC680 is packed with everything you need to install, service and troubleshoot any HVACR system. The SC680 is the top of the line Clamp Meter with wireless functionality for the HVACR professional. Send your electrical measurements directly to the Job Link® system mobile app. Leave the meter behind a closed blower door and view the current measurement on your mobile device. Help determine system efficiency by directly measuring power consumption (W) of the system. Use this value to inform your customer of energy saving measures you can take to help them save money on their energy bills. The SC680 is the only meter you'll need for troubleshooting mini-split systems. Dual Type-K temperature ports to measure entering/exiting air temperatures and measure frequency (Hz) directly with clamp jaw. Reach those cramped mini-split connectors with the included RCT2 probe tips for voltage and resistance measurements. Hang your SC680 Clamp Meter to any metallic surface with the heavy-duty magnet. When the job is done, store your test leads in the back case for tidy and convenient storage. See both voltage and amperage readings at the same time on the large dual display. Easily see your amperage readings no matter how you clamp around a wire with the swivel head AAC clamp. Verify the order of 3-ph voltage lines with just two leads. Capture L1-L2 and L1-L3 to check that motor lines are correctly installed with phase rotation test. Take more accurate VAC and AAC readings on variable frequency drives with True RMS sensing technology. Measure the starting amp draw of a compressor with Inrush current mode. Illuminate the way with a powerful LED built into the clamp jaw. Easily see your measurements with the bright blue backlight on the display. Safely change functions with the backlit illuminated dial. Take measurements more safely with one hand using the single test lead holder. Test leads come with removable gold plated tips to reliably connect Fieldpiece accessory heads.
