Fieldpiece SC260 Compact Clamp Meter | True RMS | Auto Select | HVAC/R

Fieldpiece SC260 Compact Clamp Meter — True RMS | Auto Select | HVAC/R

The Fieldpiece SC260 is a compact True RMS clamp meter designed for HVAC/R electrical testing, including work on variable frequency drives (VFDs). True RMS measurement gives accurate readings on non-sinusoidal waveforms — important when testing equipment with VFDs, where average-responding meters can give misleading results. The SC260 also features Auto Select mode, which automatically selects the appropriate measurement when you connect the leads, saving time on the job.

Extended temperature tolerances allow accurate temperature measurement from freezer environments to hot rooftops. A backlit LCD and swivel magnet enable hands-free use in poorly lit locations.

Electrical testing on live systems requires appropriate trade qualifications and licensing. Confirm licensing and compliance requirements with the relevant authority in your state or territory. Confirm all specifications against the Fieldpiece SC260 datasheet.

Frequently Asked Questions

Why does True RMS matter for HVAC/R?

Variable frequency drives (VFDs) produce non-sinusoidal waveforms. Average-responding meters can give inaccurate readings on these waveforms. True RMS meters measure the actual RMS value regardless of waveform shape, giving accurate results on VFD-driven equipment.

What is Auto Select mode?

Auto Select automatically detects what you’re measuring when you connect the leads and selects the appropriate measurement mode — reducing manual dial adjustments and saving time on the job.

What is the warranty?

1 year. Confirm current terms with HVAC Trade Supply at time of purchase.
