Mini Clamp Meter with Temperature - A Solid Performer in the Field or a Great Backup Meter - SC45
The Mini Clamp Meter with Temperature for HVAC/R, model SC45, incorporates a lot of big meter functions into a compact, easy to hold and use design. While it’s not exactly an all-in-one multimeter, this manual and auto ranging DMM includes most of the ranges you use in HVAC/R everyday. Along with standard multimeter ranges, we designed the SC45 to include capacitance (MFD) and temperature with great compensation. And to add to that, we designed it with built-in non-contact voltage and a continuity beeper to give you a powerful HVAC/R meter that’s under 8-inches tall. Makes a great backup or a solid performer for everyday testing.
How Does it Work?
The SC45 dial is easy to operate with one hand. It’s compact design allows you to select the range you need using one finger or thumb and get the job done fast. Be sure to refer to the Operator’s Manual for safety information and warnings and use safe testing practices when hooking up your multimeter to any refrigeration or heating system.
Selecting Ranges
Like the SC44, the SC45 includes a range button. A lot of technicians tell us they like that you have to think about what you’re hooking up to before you test.
To switch to manual ranging mode, simple press the range button (looks like a two-ringed bulls eye) and hold for about two seconds until the symbol appears in the upper left of the LCD.
For DC voltage, set the meter to the VDC parameter instead of VAC (shown below). For all ranges choose a range just above the value you expect. If display reads “OL” (overload), select a higher range. If display shows less than three numbers, select a lower range for better resolution.
To return to auto ranging mode press and hold the range button again for about two seconds.

Temperature
Disconnect test leads from voltage before plugging in thermocouple! Insure the temperature being measured is stable. Maintain good contact between the thermocouple and what's being measured.

Features and Benefits
Like all of our test instruments, the main benefit of the SC45 is that it was designed specifically for HVAC/R field service. It’s rugged, has with built-in safety features and includes most of the ranges you need for everyday testing. Some of the highlights include:
Temperature
Take ambient air or refrigeration line temperatures and more with the built-in K-type port and the included ATB1 wrap tab thermocouple. Add a wet sock (saturated tissue or a shoelace to take wet bulb temperatures. The built-in temperature junction offers great temperature compensation for more accurate and faster measurements.
Capacitance (MFD)
Measure microfarads on motor-start and motor-run capacitors to check for degradation. Don’t forget to discharge the capacitor before testing.
400AAC
Using the amp clamp, read 0-400 amps directly on your meter with 0.1 resolution.
Wire Grabbing Jaw
The amp clamp is shaped like a jaw to make separating and grabbing a single wire easy using only one hand.
Non-contact Voltage
With the NCV tab on the tip of the clamp close to an AC voltage, press and hold the NCV button. The NCV LED will light with an analog feel 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 (24V to 600V, 50Hz to 60Hz).
Hold
The HOLD button is easily pressed with your thumb (or forefinger for lefties) while holding the mini clamp meter naturally in your hand. It holds any reading on your SC45 so you can concentrate on the test points, disconnect, and then look at the LCD.
And More:
- Volts AC.
- Volts DC.
- Resistance (Ohms).
- Continuity.
- Range button to switch between auto and manual ranging.
- Rugged ABS case.
- Ergonomic shape fits naturally in your hand.
- Auto power-off (APO) to conserve battery life.
- Compact size – only 8” tall.
Competitive Advantages
The SC45 has features and benefits of many full-size meters in a design that is only 8-inches tall. The built-in non-contact voltage sensor (NCV) sensor tells you if a line is hot or not before you work on it. The continuity beeper tells you if a circuit is open or closed. And the hold button on the side of the SC45 allows you to concentrate on the test point, hold the reading and then look at the display after you’ve disconnected.

Deluxe Silicone Test Lead Kit - ADK7
The ADK7 deluxe silicone lead is the optimal way to test most electrical parameters you run into during field service. The kit includes the ADSL2 silicone leads and ASA2 alligator leads plus our all new RCT2 "Molex"-style probe tips. HVAC techs often remove the black probe tip (common) and insert the black alligator lead for an extended reach from ground. When used with our stick meters, the Volts (red) probe tip is inserted into the top of the meter for easy one-handed testing. Use both alligator extension to perform “no-hands” tests. Silicone test leads deliver better performance in temperature extremes than test leads insulated with vinyl.

Field Temperature calibration 
For accuracies of ±1°, calibrate to a known temperature. A glass of stabilized ice water is very close to 32°F (0°C) and is usually very convenient but any known temperature can be used.
- Select 400°F/C range and connect thermocouple.
- Remove back case (2 screws on back, one near clamp, other near base). Leave battery cover attached so batteries stay within back case.
- Stabilize a large cup of ice water.
- Immerse the thermocouple tip and let it stabilize.
- To change the temperature scale to °C, close the jumper just below VR5.
- Adjust VR5 calibration pot with a small screwdriver to get within 0.1° of 32°F (0°C). Each 1/4 turn should adjust the temperature about 3°, no more than 10° total. There’s no need rotating the screw more than 360°; doing so gets you back to where you started.
- Attach case without screws to preview the temperature and continue until you have it dialed in.
