HVAC/R Clamp Meter with Temperature and Capacitance - A Value but Not the “Little Brother” - model SC76
Calling the SC76 the “little brother” of the SC77 is unfair. The SC76 also has most parameters for electrical and thermal HVAC/R testing in one meter. It includes a host of safety features like a high-voltage LED and beeper, a continuity warning, push button non-contact voltage (NCV), a lead holder with detachable leads and alligator probe tips for easy one-handed testing, and more. As far as ranges go, it too has temperature, capacitance, microamps DC for flame diode tests, and everyday electrical ranges for HVAC/R. Many technicians tell us they enjoy the choice between manual and auto-ranging. It’s a lower priced all-in-one clamp meter for technicians who don’t need the backlight or True RMS functions. It’s a rugged workhorse you can count on to get the job done easier, faster, and more safely.
The Fieldpiece SC76 HVAC/R Clamp Meter is a rugged HVAC/R meter through and through. The Fieldpiece SC76 is a natural fit in the user's hand; The Fieldpiece SC-76 feels solid and has a bit of balanced weight to it. Add to that virtually every electrical parameter you need for HVAC/R field service and temperature. The Fieldpiece SC/76 also works with Fieldpiece accessory head instruments and includes a host of safety features, detachable leads, and warnings.
Designed specifically for HVAC/R field service, the Fieldpiece SC66 Manual Ranging Clamp Meter with Temperature is a dedicated DMM and offers specific features and benefits to HVAC/R field service pros including:
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).
High Voltage and Continuity Indicators
If the user is using the Fieldpiece SC66 while doing lab testing, these features would probably drive you crazy. Fieldpiece took input from more than one HVAC/R veteran in order to make sure that these features really remind the user of what they're doing and they’ve avoided potentially dangerous situations in the field. The Hi-V LED and beeper let you know when you’ve hooked up to a circuit over 30V. The continuity LED and beeper tells the user if a circuit is open or closed.
Using the built-in amp clamp, the user can use the Fieldpiece SC 66 to read 0-200 amps directly on your meter with 0.1 resolution.
With the Fieldpiece SC66, users can measure microfarads on motor-run and motor-start capacitors using the Capacitance range. To use, first disconnect the capacitor from power first, then Short the terminals to discharge the capacitor. Disconnect any resistors that might be between the terminals of the capacitor and measure to check for degradation.
Take ambient air or refrigeration line temperatures and more with the built-in K-type port and the included the Fieldpiece 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.
Microamps DC - Flame Rectification Tests
The most common "no heat" call has to do with a malfunctioning flame sensing diode. Simply turn the Fieldpiece SC66 Clamp Meter to microamps DC, hook up, and see if the flame sensing rod is functioning properly.
Because the wire insulation is silicone, the leads stay flexible in cold weather and will not melt if bumped by a soldering iron. Use the attached lead clip on the to help the user perform a one-hand test more easily than most meters on the market. Built-in lead storage makes it easy to keep everything together from job to job. Fieldpiece's Deluxe Silicone Lead Kit, model ADK7, is an optional purchase from your favorite distributor and makes one-handed testing even easier.
Jaw The Fieldpiece SC 66's fixed jaw is longer than the moveable jaw to make it easier to select just one wire from a bundle. With the jaws closed, separate one wire using the long fixed jaw then slide it to the corner where the two jaws meet; Finally, open the jaws to let it in. Now you can select the wire without holding the jaws open.
The MAX hold button is easily pressed while holding the mini clamp meter naturally in your hand. The Fieldpiece SC66 holds the maximum reading when hooking up to a test point. The Fieldpiece SC66 Dual Display Mini Clamp Meter for HVAC/R is a safer way to test, so you can concentrate on the test points and look at the LCD after you’ve disconnected.
How Does it Work?
The SC76 is an all-in-one DMM that with a dedicated amp clamp. Use the NCV button to determine whether on not a wire or circuit is live. The high-voltage indicators alert you when hooking up to 30V or more, while the continuity indicators tell you if a circuit is open or closed. Operation of the SC76 is easy. Simply select a range and test Use annual ranging to make you think about what you’re hooking up to or the added convenience and speed of auto-ranging. The display automatically shows you the appropriate range for the parameter being tested on the large LCD, An “OL” message warns you that the test is out of range for the meter.
For DC voltage, set the meter to the VDC parameter instead of VAC as shown below. For all ranges and functions choose a range just above the value you expect. In auto ranging mode the display will automatically change to accommodate the parameter being tested. If display reads "OL" (overload), select a higher range. If display shows less than three numbers, select a lower range for better resolution.
The SC76 is a rugged HVAC/R meter through and through. It’s a natural fit in your hand; it feels solid and has a bit of balanced weight to it. Add to that virtually every electrical parameter you need for HVAC/R field service and temperature. It also works with Fieldpiece accessory head instruments and includes a host of safety features, detachable leads, and warnings.
Like all of our instruments, we designed this meter exclusively fit the way you do your job. We took out some of “nice to have” features of the top of the line model to give you the option of manual ranging and spending a little less.
