Read amps and volts at the same time with the Dual-Display Mini Clamp Meter for HVAC/R, model SC52. Measure any other range on the meter simultaneously with an amp measurement. The SC52 is compact measuring only about 8-inches, easy to use and includes many of the ranges you use everyday during HVAC/R field service. It includes the ranges for flame diode rectification and a diode test for checking circuits, as well as built-in safety features like non-contact voltage, a hold button and a continuity tester with audible alarm.
How Does it Work?
The SC52 is an auto ranging DMM that with a dedicated amp clamp and display, as well as a display for the rest of the ranges on the meter. When you select a range and hook up to the circuit, the SC52's bottom display automatically includes symbols or proper decimal places for the range you are testing. If you are out of the given range on this meter you will receive and "OL" message. The push button non-contact voltage feature allows you to determine whether a line is hot or not right on the meter.
Features and Benefits:
The SC52 display allows you to read amperage while testing any other function on the dial. More tests at one time means the job gets done right and the job gets done faster.
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).
Using the built-in amp clamp, read 0-400 amps directly on your meter with 0.1 resolution.
Microamps DC - Flame Rectification Tests
The most common "no heat" call has to do with a malfunctioning flame sensing diode. Simply turn the SC52 to microamps DC, hook up, and see if the flame sensing rod is functioning properly.
Wire Grabbing Jaw
The amp clamp is shaped like a jaw to make grabbing a single wire easy using only one hand.
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 SC52 so you can concentrate on the test points and look at the LCD after you've disconnected.
