Product Highlights
Unlike meter testers that only “verify,” the RM‑17 incorporates a true RADIAN standard as its internal reference, delivering a guaranteed ±0.05% accuracy that is traceable to NIST. Automated testing uses site voltage and a synthesized phantom current source up to 50 Amps.
The built‑in reference standard—and its repeatability—helps validate a meter’s performance with confidence and supports reliable testing in both today’s residential environments and evolving solid‑state meter programs.
Features
Accurate, Precise Field Testing
- Automated on‑site testing for residential billing meters with clear, easy‑to-follow procedures—practical for both experienced technicians and non‑metering personnel handling billing complaint testing.
- Paperless workflow support: store up to 100 test result sets in the hand controller, upload results to a PC later, and maintain strong record integrity with time/date stamps plus User ID and Meter ID fields.
- Standardized test procedures across crews: create and store multiple test configurations, build standard setups on a PC using WATT-Net, and distribute those setups to multiple hand controllers for consistent field execution.
- Broad residential test coverage with support for Form 1S, 2S, 2SE, 12S (network), 12SE, and 25S meters.
- Supports key test points such as light load, full load, and 0.5 lagging power factor, aligning with common residential meter testing expectations.
Portable Meter Test System
A Billing Complaint Test, Step by Step
- Set up at the meter socket with the RM-17 socket adapter, following your utility’s procedures for removing and setting meters.
- Attach a pickup: an RR-IR optical pickup for solid-state meters, a disk sensor for induction meters, or a KYZ pulse input adapter.
- Run the test. The RM-17 uses site voltage and its own synthesized current to test light load, full load and 0.5 lagging power factor, with optional demand and creep tests.
- Save the result with a time/date stamp, User ID and Meter ID, then transfer the data to a PC using WATT-Net.
Which Tester Is Right for You?
The RM-17 is built for one job: testing residential meters in service, quickly and with a true RADIAN reference standard. For other meter tests, the table shows which RADIAN tool fits.
| Model | Best for |
|---|---|
| RADIAN RM-17 | High bill complaint testing of residential meters |
| Bantam Plus | Automated testing of meter forms 1S through 96S, in the shop or the field |
| RADIAN RW-30X / RW-31X | Complete meter site analysis when you need to source up to 30 A and 480 V |
| RADIAN RM-111 | Comparing a reference standard against other standards, test boards or meters |
RADIAN RM-17 FAQ
Which meters can the RM-17 test?
Socket meter forms 1S, 2S, 2SE, 12S (network), 12SE and 25S, in classes 100, 200 and 320. It tests both solid-state and induction meters.
How accurate is the RM-17?
The RM-17 has a true RADIAN watthour reference standard built into its socket adapter. Accuracy is ±0.01% typical and ±0.05% guaranteed, at unity and 0.5 lagging power factor, traceable to NIST. It ships with a calibration report, and RADIAN Calibration Services recalibrates it.
Does the RM-17 need customer load to test?
No. It uses site voltage (60 to 600 VAC, autoranging) and a synthesized phantom current source up to 50 A, so the test does not depend on what the customer is using at the time.
Can the RM-17 test demand and creep?
Yes. It runs a kW demand test over an interval you set, and an ANSI in-service creep test that you can turn on or off in the test setup. It also calculates and stores a weighted average with every result.
How are test results stored and shared?
The hand controller stores up to 100 test result sets, each with a time/date stamp, User ID and Meter ID. Transfer the data to a PC using WATT-Net.
