Features and Benefits of the Fieldpiece SC260

The Fieldpiece Clamp Meter SC260 targets the HVAC professional — but does this machine offer more to the DIYer and trade contractor than just heating, refrigeration, and aircon troubleshooting?

Time to scrutinize the unit to reveal its capabilities.

Temperature Testing

As an HVAC-focused machine, the SC260 naturally includes a temperature testing function — a feature that didn’t appear on its predecessor, the Fieldpiece Clamp Multimeter SC220.

Measuring heat output from -30 to 752 degrees Fahrenheit, it can address heating elements, condensers, exchange units, and evaporators. And, arriving complete with a Type K Thermocouple adapter — there’s no requirement to make an additional purchase to use this setting.

However, what separates this machine from the plethora of other temperature testing clamps and multimeters, is its insulated heat resistance system. This allows you to switch immediately from cold to hot environments — and vice versa — without skewing the results.

Furthermore, this heat scrutinizing system isn’t just for the HVAC pro. For the home user, temperature testing is crucial for automotive enthusiasts — or for troubleshooting consumer products such as kettles, hairdryers, and heat guns.

Swivel Magnet

If you’re an experienced circuit tester — you know you never have enough hands. It’s impossible to wield a multimeter in your palm, while simultaneously attaching twin testing probes to a circuit board.

Hence, it’s pleasing to see that the rear of the Fieldpiece SC260 boasts a rotating magnetic. Powerful and generously sized, it permits you to securely attach the machine to heating or air-con casings — leaving your hands free to position the testing tips. And, with its swivel feature — you can rotate the clamp meter while in situ for the most comfortable reading position.

CAT III Rating

As a genuine pro-grade tool, the Fieldpiece Clamp SC260 possesses a CAT III safety rating, permitting the machine to be used with three-phase electrical installations — commonly found in industrial and factory environments.

While this will be sufficient for most amateur and light contractor users, it will be unusable for pro electricians dealing with high energy loads — such as mains utility distribution systems that require CAT IV certification. Should you want to know more about CAT ratings and their importance, check out my guide here.


When addressing air-con, refrigeration, and heating machines — accurate circuit testing is crucial. Additionally, if you’re a home electronics enthusiast scrutinizing PCBs (printed circuit boards) — any lack of precision can lead to blown capacitors or burnt-out CPUs.

Therefore, it’s pleasing to see that the SC260 Fieldpiece incorporates TRMS (True Root Mean Square) technology — delivering more precise results than standard RMS units.

By eliminating electrical noise from computer power transformers, fluorescent lights, and rotary motors — the risk of false readings is dramatically reduced.

Should you want to learn more about TRMS, how it works, and why it’s crucial for DIYers and pros, check out my TRMS 101 article.

Compact Build

Measuring just 8.0 x 2.65 x 1.77 inches — the Fieldpiece Clamp Meter SC 260 is one of the smallest temp testing machines on the market. This may appeal to both amateurs and trade pros who find themselves operating in closed spaces.

And, as these challenging confined locations are typically poorly illuminated — it’s rewarding to witness that the unit features an LCD backlight.

Auto Select Mode

With auto-ranging, you don’t need to have a professor-like grasp on the intricacies of resistance banding or capacity ratings — the SC 260 automatically chooses the correct range (tens, hundreds, thousands, etc.) for the measurement of voltage, current, frequency, and resistance.

Furthermore, even if you’re a highly experienced pro user who has a thorough understanding of electrical nuances — auto-ranging can save you valuable downtime, as there’s no requirement to reset and recalibrate dials.

Additional Accessories

When you purchase the SC 260 Fieldpiece, you don’t just receive the clamp meter unit. In addition, this electrical tester also arrives with:

  • Velcro securing strap.
  • Silicon testing leads with gold probe tips.
  • Wrap-tab Type K Thermocouple adapter.
  • 9-volt battery.
  • Padded carry case.

Fieldpiece SC260 Vs Fieldpiece SC220

Twelve months ago, the bigwigs at Fieldpiece removed the SC220 from its clamp meter line-up and replaced it with the SC260.

Visually and functionally, the two units are almost identical, except for two differences:

  • The SC 260 has a temperature tester, whereas the SC220 did not.
  • The SC 220 boasted a micro-amp facility, not a feature of the newer SC260.

What Do Users Say About the Fieldpiece Multi-Clamp Meter SC260?

As I’ve already explained in this Fieldpiece SC260 review, I consider this machine to be a solid HVAC targeted clamp meter that can also function as an all-purpose home circuitry tester.

Yet, with only limited experience of the unit, the scope of my examination can only go so far. Hence, to ensure a completely thorough appraisal, I sought the opinions of SC260 owners — to gauge how DIYers and trade professionals felt about its features and capabilities.

Reassuringly, their feedback was positive.

Frequent users of the SC 260 Fieldpiece applauded the inclusion of temperature testing — something that wasn’t available on its predecessor, the Fieldpiece Clamp Meter SC220 Compact. Furthermore, they welcomed the inclusion of a reverse-mounted swivel magnet, and commended the industry-grade CAT III rating.

However, there were a couple of guys who expressed some disapproval.

One HVAC engineer criticized the machine for being unable to measure micro-amps — a facility that was offered by its earlier incarnation, the SC220 Fieldpiece Compact Clamp Meter. Additionally, a laptop technician bemoaned the fact that there are no storage recesses for the probes.

But, overall, all users concurred that the Field Piece SC260 was a reliable and accurate TRMS clamp meter that is more than sufficient for air, heating, and DIY users.
