Fieldpiece SC200 Series
In this section, we're going to take a brief look at each of the Fieldpiece clamp meters on offer and discuss the features and how they relate to HVAC work. Fieldpiece clamps start with the SC220 and move up in numerical order to the new Fieldpiece SC680. As you've likely guessed, each higher numbered model increases in features and price, so you'll want to assess your needs and then make the best choice based on your specific job requirements. This short little guide will help. The Fieldpiece SC220 is the entry-level model with a variety of great features for HVAC. It works as a great backup meter, though you may want to invest a little more for your main meter. The SC220 reads AC/DC volts, AC current, microamps DC (for flame sensors in a furnace), resistance, and continuity. However, the SC220 is the only meter in the SC2xx series that reads microamps DC, so it's going to be your go-to for an inexpensive meter if your primary focus is heating work. Moving up the line to the SC240, we're going to add the ability to test capacitance (the importance of which we looked at above) and to test temperature. Now neither meter so far is TRMS. For most accurate results, you do want to get a TRMS meter, so enter the Fieldpiece SC260. This one is by far the most popular entry-level Fieldpiece clamp meter. The SC260 also adds a few convenience features like an LCD backlight and a magnetic hanger. Do remember that only the SC220 reads microamps, so for heating focused work, you'll want that or you'll want to make the jump the SC420.
Fieldpiece SC400 Series
The Fieldpiece SC420 is pretty similar to the SC220 but has some convenience features like a dual display, and most importantly, capacitance. It also will tell you duty cycle percentage and can read frequency using the clamp and leads. The SC420 is not TRMS and doesn't have a backlight, so it will be your go-to for a budget-friendly model if you do both AC and heating work. Clearly stated, if you want an excellent meter that is gentle on your wallet: SC220 for heating, SC420 for both heating and AC. Now, the Fieldpiece SC440 adds back in those convenience features like the LCD backlight and magnetic strap. Most importantly, it is a TRMS meter and reads Inrush current, as we discussed above. Those are the two primary advantages of picking up the SC440, and they are important ones. The Fieldpiece SC460 is a big jump up in features with a lot of smart-features for reporting and wireless app communication; however it relies on the JL2 joblink port and is being largely overtaken by the brand new Fieldpiece SC480, which connects directly to a smart device App. So let's take a look at the Fieldpiece SC480, the powerhouse choice in the SC4xx series. The SC480 reads everything discussed thus far plus it reads Power in kW, is TRMS and features a Low-Pass filter for accurate readings on variable frequency drives, checks 3 phase motor rotation, has Molex tipped leads for reaching into power connectors, and is safety rated to CAT IV-600V. Honestly, it blows the rest of the series out of the water and, most importantly for the modern job site, reports all this info back directly to a mobile app that can generate and print reports. Professionals working on mini-splits or even larger commercial units will want to consider this unit as the best investment in the series.
Fieldpiece SC600 Series
The Fieldpiece SC620 is the lowest price entry in this advanced series. This meter is the one to go for if you need higher-end convenience features like a swiveling clamp head for working in tight or awkward spaces, a magnetic strap, and on-board storage for all your leads. The SC620 essentially adds on these physical features to the measurement capabilities of the SC420 that we discussed above. You'll want the SC620 if you're on a budget but really want the extra physical features on this upper model Fieldpiece clamp meter. Do keep in mind that is does not have a backlight, inrush current measurement, or TRMS. The Fieldpiece SC640 is the way to go if you want to add in those three features I just mentioned. Fieldpiece likes to make clamp meters available to every price point, but if finances allow, between the two, you are better off with the SC640. That model was the top model offered by Fieldpiece until the introduction of the newest powerhouse meter, the SC680.
The Fieldpiece SC680 is the cream of the crop for HVAC/R clamp meters. All the features mentioned in the previous paragraphs are included plus a whole lot more. Like the SC480 we talked about above, the SC680 connects wirelessly to the App for field reports that are shareable and printable. You'll be able to measure Power in kW, use Low-Pass filter variable frequency drives, and check 3 phase motor rotation. It also comes Molex tipped leads for power connectors and is also safety rated to CAT IV-600V.
Additionally, the SC680HVAC clamp meter measures DC Amps for working with mini-split inverters, a dual temperature mode for measuring Delta T, and includes all the convenience features from the other Fieldpiece SC600 series meters, like a swivel clamp head and lead storage. The one really cool and unique feature on the SC680 that we've not seen in another HVAC clamp meter is a backlit dial. This feature allows you to work in dark areas and still see which measurement mode you've selected. Technically you could guess and check by viewing the backlit screen, but being able to see what you're doing while making your selections adds another layer to the ease-of-use factor. Overall, the Fieldpiece SC680 clamp meter is the pinnacle of the Fieldpiece catalog when it comes to HVAC clamps. This meter is the one to beat in today's market.
