Safety Information Understand and follow operating instructions carefully. A Warning identifies conditions and procedures that are dangerous to the user. A Caution identifies conditions and procedures that can cause damage to the Product or the equipment under test. ! WARNING To avoid possible electric shock, personal injury or death, follow these guidelines: • Use the meter only as specified in this manual; otherwise, the protection provided by the meter may be impaired.
flash from short circuits. Do not place magnet inside Category IV panel. Place it outside the panel instead. • CAUTION To protect yourself, think “Safety First”: • Voltages exceeding 30VAC or 60VDC pose a shock hazard so use caution. • Use appropriate personal protective equipment such as safety glasses, face shields, insulating gloves, insulating boots, and/or insulating mats.
Description Your 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.

Amps AC (AAC) True RMS (50-60Hz) + Test isolated power lines. Press SELECT on VAC/100AAC/Hz or VAC/600AAC/Hz position. Read AAC in upper display and VAC on the lower display. For AC current <100AAC, select VAC/100AAC/Hz switch position and for AC current >100AAC, select the VAC/600AAC/Hz switch position.

MicroAmps DC (µADC) Test flame rectifier diodes on a heater control. Connect leads between flame sensor probe and control module. Turn heating unit on. When the flame is on, there should be a measurable µADC signal, typically under 10µADC. Compare measurement to manufacturer’s specification to determine if replacement is necessary. Ranges: 1000µA Resolution: 0.1µA Accuracy: ±(1.
Resistance (Ω) HOLD Used for O“ohming Hz out” a compressor. A 0.01Ω resolution is useful to test the resistance between the terminal poles because the values are F AAC AC For F Vlow.

Dual Temperature (T1, T2, T1-T2) Plug any Type K thermocouple directly into the meter to measure temperature. Test for proper airflow across the evaporator coil by measuring delta T with the dual temperature inputs. Insulated cold junction is located inside the meter and allows for accurate measurements even in rapidly changing ambient temperatures (going from rooftop to freezer). No adapter is required. By default, T1 will show on top display and T2 on bottom display.
Power (Watts, VAr, VA, WDC, PF) Help determine system efficiency by measuring the power exerted by the system. The actual power consumed by the system is called Active Power and is measured in watts (W or kW). Reactive loads, inductors and capacitors, dissipate zero power, but they drop voltage and draw current giving the deceptive impression they do dissipate power. This is called Reactive Power and is measured in Volt-Amps-Reactive (VAr).
Phase Rotation Test (L1L2, L1L3) Connect 3-phase power lines in the correct order to the terminals of a motor to ensure the motor turns in the intended direction. Incorrect wiring can damage some equipment. The terminals on the motor are usually marked L1, L2, and L3; however, the wires supplying power usually are not. Perform a simple phase rotation test with two test leads to quickly identify the order of 3-phase power lines. Range: 80±5 VAC to 600VAC (50Hz to 80Hz) Resolution: 0.1V Accuracy: ±(1.
Phase Rotation Testing Tips 1 The measured voltage during phase rotation test must be >80.0±5VAC. If not, the phase rotation test can not be performed and “Err” will show on the top display. 2 After phase rotation test is complete, press SELECT button to begin a new phase rotation test. 3 Be sure to connect test leads to 3-phase voltage lines for at least 2 seconds until voltage reading holds on the bottom display 4 Phase rotation test cannot be performed on Hifrequency voltage signals.
Works with Job Link® System Do More with the Job Link® System Directly document critical electrical measurements at the job site, and add them to professional PDF reports. No separate transmitter required. Combine your new clamp meter with other Job Link System tools to create seamless reports. Show customers what needs to be done (Pre-work) and prove how that work helped (Post-work).
RUSH OFF Battery Replacement When your meter’s battery is low, the battery icon will appear empty and blink for 30 seconds. “bAtt” will display and meter will power off. Turn dial to OFF position, disconnect test leads and remove the battery cover with magnet strap on the back of your meter. Remove old battery and replace with a standard 9V battery only. Be sure to re-insert the magnet strap before re-installing the OFF battery cover.
