AUTO RANGING DIGITAL CLAMP METER Model SC76
Works with Fieldpiece accessory heads!
!WARNINGS !
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 °F.
REMOVE THE THERMOCOUPLE when taking voltage measurements.
DISCONNECT THE TEST LEADS when taking temperature measurements.
DO NOT APPLY VOLTAGE TO THE JACKS when the rotary dial is on microamps. Even low voltages can cause a current overload and blow the fuse. Replace blown fuse to regain function.
Maintenance
Clean the exterior with clean dry cloth. Do not use liquid.
Battery replacement: When the multimeter displays " 
" the battery must be replaced. Disconnect and unplug leads, turn meter off, and remove the battery cover. Replace the battery with a NEDA type 1604 9V battery.
For your safety...
General: Disconnect the test leads before opening the case. Inspect the test leads for damage to the insulation or exposed metal. Replace if suspect.
Never ground yourself when taking electrical measurements. Do not touch exposed metal pipes, outlets, fixtures, etc., which might be at ground potential. Keep your body isolated from ground by using dry clothing, rubber shoes, rubber mats, or any approved insulating material. When disconnecting from a circuit, disconnect the
"RED" lead first, then the common lead. Work with others. Use one hand for testing. Turn off power to the circuit under test before cutting, unsoldering, or breaking the circuit. Keep your fingers behind the finger guards on the probes. Do not measure resistance when circuit is powered. Do not apply more than rated voltage between input and ground.
All voltage tests: For model SC76 all voltage ranges will withstand up to
600VDC or 600VAC. Do not apply more than 600VDC or 600VAC.
AC tests: Disconnect the meter from the circuit before turning any inductor off, including motors, transformers, and solenoids. High voltage transients can damage the meter beyond repair. Do not use during electrical storms.

OPERATOR’S MANUAL
Works with Fieldpiece accessory heads
Connect your Fieldpiece accessory head to SC series meter through included deluxe silicone leads. Use 340mVDC or 3400mVDC range for most heads.
SC76 connected to
ARH4 through leads.
Available Fieldpiece accessory heads
There is a Fieldpiece accessory head available for just about any job. There are heads to measure temperature, RH%, wet bulb, dew point, vacuum (microns of mercury), manometer
(inches of water column), amps
AC&DC, high voltage, CO, CO2, air velocity, and many more.
Non-contact voltage
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
NCV function is sensitive enough to
detect 24VAC on thermostats.
Hi voltage indicator
In any VAC/VDC range, when you touch a voltage greater than 30V, the beeper will beep and the red Hi-V LED
will blink. BE CAREFUL!
Current measurements
The fixed jaw is longer than the moveable jaw to make it easier to select just one wire from a bundle.
With the jaws closed, separate one wire using the long fixed jaw. Slide it to the corner where the two jaws meet. Then open the jaws to let it in. You can select the wire without having to hold
the jaws open.
Microamps
For measuring the flame diode current in a heater control.
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.
Temperature
Plug any K-type thermocouple directly into the meter to measure temperature. Temperature measurement will maintain good accuracy in fast changing environments. One thermocouple is included. No adapter is
required.
Display ºC or ºF
Remove back of meter, locate jumper on lower right corner of PCB
(just below VR3) and close jumper to
read temperature in °C.
Field Temp. calibration
For accuracies of ±1° calibrate the
SC76 to a known temperature. A glass of stabilized ice water is very close to 32°F (0°C) and is usually very convenient.
1.Select the °F range on the SC76.
2.Remove back case. Hold the battery in place with a rubber band.
3.Stabilize a large cup of ice water.
4.Immerse the probe and let it stabilize.
5.Adjust VR3 (lower right corner of
PCB) to get close to 32°F (0°C) then adjust VR4 (below VR3) to get within 0.1°F/C of 32°F (0°C).
6.To calibrate in °C, close the jumper that is to the left of VR3.
Using & storing test leads
Because the wire insulation is silicone they will stay flexible in cold weather and will not melt if bumped by a soldering iron.
Use the single test probe holder on clamp to make voltage testing easy.
For convenient lead storage, wrap the leads as shown.
