Mini Clamp Meter for HVAC/R – Compact and Affordable - SC44
The SC44 Mini Clamp Meter for HVAC/R is a basic, affordable clamp-on meter designed for HVAC/R field service. It 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 they’re hot or not. The range button (Looks like a two ring bulls eye) switches the SC44 between a manual ranging meter and an auto ranger. The small size 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 SC44 is Cat.III 600V rated.
How Does it Work?
Check to see if the circuit is hot using the Non-Contact Voltage (NCV) button. Use the wire grabbing jaw to easily separate wires when taking current readings. Switch to AAC to test. Select any other range and use the included test leads to measure.
Selecting Ranges.
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.
Competitive Advantages.
The SC44, while a basic mini clamp-on meter, it’s a solid performer and built exclusively for the work you do. Other small meters often lack the durability, ranges, ratings and resolution you need in a good backup meter. Like all of our clamp meters, the SC44 includes the built-in Non-Contact Voltage (NCV) tester, to save you time during a service call and space in your pocket or tool bag.
