Product Highlights
The 3302 pairs its ±0.05% three-phase reference standard with the analysis tools technicians use to find site problems: vector diagrams, voltage and current waveforms, harmonics to the 50th, and RMS data. Three direct current inputs handle up to 20 A, and clamp-on probes extend the range for larger services.
Powermetrix Remote Manager (PRM) software controls the 3302 wirelessly from a Windows device up to 100 feet away, including in high-EMF environments, and supports data trending. Every 3302 ships with a NIST-traceable calibration report and a two-year warranty.
Features
- CAT IV 600 V and IEC 61010 safety rating for field conditions.
- ±0.05% three-phase reference standard with calibration verification pulse input and output.
- Vector, waveform, harmonic (to the 50th), and RMS analysis for troubleshooting and wiring verification.
- Three direct current inputs up to 20 A, plus clamp-on current probe options up to 1,000 A.
- Test suite: customer load meter testing, demand and register testing, CT and PT ratio testing, and CT and PT burden measurement.
Handheld Three-Phase Site Testing
- Connect the voltage leads and current inputs, direct up to 20 A or through clamp-on probes.
- Check the site: vector diagrams and waveforms confirm the meter is wired correctly.
- Test the meter on customer load with the magnetic IR pulse detector, then run register and demand tests.
- Test the CTs and PTs for ratio and burden, and save the results with PRM software.
Build Your 3302 Kit
Start with the 3302 for testing on customer load, and add a module when you need to source current or test CT burden. Each module also serves as the carrying case for the 3302 and its accessories, and existing 3302 owners can add one later.
Need more? The Powermetrix 6618A with the 335V adds a voltage source and expanded burden testing compared with the 3302 with the 335. The RADIAN RW-30X and RW-31X source up to 30 A and 480 V, with test data managed in WATT-Net.

|---|---|---|
| 3302 | — | Customer load meter testing, CT and PT ratio and burden, and site checks |
| 3302 + 303 | CT burden-add testing up to 2 ohms | Confirming CTs hold accuracy under added burden |
| 3302 + 305 | Three-phase current source for meter testing up to 5 A | Testing meters when customer load is low or absent |
| 3302 + 335 | Current source up to 5 A and CT burden-add up to 2 ohms | The complete 3302 kit |
Powermetrix 3302 FAQ
What can the Powermetrix 3302 test
The 3302 tests meters on customer load, checks register and demand, tests CT and PT ratio, measures CT and PT burden, and verifies wiring with vector diagrams and waveforms, all with a ±0.05% three-phase reference standard.
How does the 3302 compare with the 6618A and RW-30X
The 3302 is the most compact of the three: a handheld analyzer with a ±0.05% reference standard and direct current inputs up to 20 A. Paired with the 335, it adds a current source and CT burden testing. The Powermetrix 6618A with the 335V goes further, adding a voltage source and expanded burden testing. The RADIAN RW-30X and RW-31X provide complete meter site analysis when you need to source up to 30 A and 480 V, with test data managed in WATT-Net.
Can the 3302 test meters without customer load
Yes, with the 305 or 335 module. Both add a three-phase current source for meter testing up to 5 A that generates ANSI-compliant current waveforms with harmonics. The 335 also adds CT burden-add testing up to 2 ohms.
Which current probes work with the 3302
The 3302 accepts current directly up to 20 A. Clamp-on options include the MN134 (10 A), MN353 (0.05–150 A), SR752 (0.1–1,000 A or 0.1–300 A), and a 36-inch flexible probe up to 1,000 A, all rated 600 V.
What software and warranty come with the 3302
The 3302 includes Powermetrix Remote Manager (PRM) software and a NIST-traceable calibration report. It carries a two-year warranty, and the 303, 305, and 335 modules carry a one-year warranty.
