3. DIGITAL CLAMP SC67 METERS SC66 General description Models SC66 and SC67 have special features for the HVAC R service technician who wants to carry one instrument OPERATOR S MANUAL Non contact voltage NCV With the NCV tab on the tip of the clamp close to an AC voltage press the NCV button the NCV LED will light and the beeper will beep The closer you get to AC voltage the louder the beep The NCV function is sensitive enough to detect 24VAC on thermostats Microamps DC For measuring the flame diode current in a heater control The clamp meter is protected by a PTC resistor not a fuse When an overload occurs on HADC reset the PTC by disconnecting from the circuit for at least 30 seconds Capacitance For motor start and motor run capacitors Disconnect the capacitor from power first Short the terminals to discharge the capacitors Disconnect any resistors that might be between the terminals of the capacitor Auto power off To extend the life of your battery the meter automatically turns off after approximately 60 minutes A WARNINGS A DISCONNECT AND UNPLUG TEST LEADS before opening case TEST NCV FUNCTION ON KNOWN LIVE WIRE before using DO NOT APPLY VOLTAGE greater than 30VAC or 60VDC to the thermocouple or the jacks when the rotary dial is on OF REMOVE THE THERMOCOUPLE when taking voltage measurements DISCONNECT THE TEST LEADS when taking temperature m
