The Fieldpiece SC44 600V Mini Clamp Meter for HVAC/R is a basic, affordable clamp-on meter designed for HVAC/R field service. The Fieldpiece SC-44 measures Amps AC, Volts AC, Volts DC, resistance, continuity, and includes a diode check. A built-in Non-Contact Voltage (NCV) sensor allows you to test thermostats and circuits to see if the thermostat is hot or not. The Fieldpiece SC44's range button (Looks like a two ring bulls eye) switches the Fieldpiece SC44 between a manual ranging meter and an auto ranger. The small size of the SC44 fits easily in your hand. Keep it in glove box as a backup meter or hang it on your belt to take measurements in tight places. The Fieldpiece SC44 Mini Clamp Meter is ratedfor HVAC/R at Cat.III 600V.


Features and Benefits

While the Fieldpiece SC44 is a basic HVAC/R multimeter, it is backed by the Fieldpiece name. Designed to be as durable as any Large handheld meters, The Fieldpiece SC44 is easy to use during field service calls. The Fieldpiece SC44 also gives you the choice of manual or auto ranging with the push of a button. The built-in non-contact voltage sensor range works on thermostats and larger lines. The Fieldpiece SC44 is compact, easy to use and comes with a Cat. III 600V rating unlike many similarly priced meters.

Non-contact Voltage
With the red NCV tab on the tip of the meter close to an AC voltage, press and hold 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 (24V to 600V, 50Hz to 60Hz).

Using the attached amp clamp of the Fieldpiece SC44, 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.

The HOLD button is easily pressed with the thumb while holding the mini clamp meter naturally in the user's hand. The Fieldpiece SC-44 holds any reading on the SC44 so the user can concentrate on the test points and look at the LCD after being disconnected.


The User can check to see if the circuit is hot using the Non-Contact Voltage (NCV) button. By using the wire grabbing jaw, it easily separates wires when taking current readings with the Fieldpiece SC 44. Proceed to switch to AAC to test; Select any other range and use the included test leads to measure.

Fieldpiece SC44 Dial Settings/Ranges

Selecting Ranges
For DC voltage, set the Fieldpiece SC44 Mini Clamp Meter for HVAC/R to the VDC parameter instead of VAC. For all ranges, the user will 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.
