The SC46 True RMS Mini Clamp Meter with Temperature and Backlight packs the biggest punch in the SC40 series. With features that rival many full-sized clamp-on meters, this auto ranging DMM packs a ton of functions into a compact, easy to handle shape. It includes temperature and capacitance as well as a bright green backlight and True RMS for more accurate readings on non-sinusoidal AC waveforms. It also packs in most of the other HVAC/R ranges you use everyday. Some technicians use the SC46 as their everyday DMM, others as back-up or second meter to get more testing done in less time. This mini-clamp was deigned to make your job easier, safer, and faster no matter where you choose to rank it in your bag.
How Does it Work?
The SC46 dial is very easy to read and operate with one with one hand. Simply select the range you're testing and get the job done. 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 A/C or heating system.
Features and Benefits:
Digital multimeters use two different types of AC sensing. The most common is average sensing, normalized to a true RMS value of a sine wave. The other is true RMS sensing. The actual true RMS value is sensed for a wave form within the limits of the crest factor. Either sensing method will give the same results on a clean sine wave but they may differ on a non-sinusoidal waveform.
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.
Measure microfarads on motor-start and motor-run capacitors to check for degradation. Don't forget to discharge the capacitor before testing.
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 grabbing a single wire easy using only one hand.
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).
The HOLD button is easily pressed with your thumb while holding the mini clamp meter naturally in your hand. It holds any reading on your SC46 so you can concentrate on the test points and look at the LCD after you've disconnected.

very good product for price

Comments about SC46, True RMS Mini Clamp Meter w/ Temperature & Backlight:
i recently purchase the sc46 and have been very pleased with its performance. the only drawback that i've found is that it doesn't do microamps for testing flame sensors and thermocouples. besides that, its small size is perfect for a grab and go trouble shooting situation. good product.
Bottom Line Yes, I would recommend this to a friend
