Calmu3 (possibly Calmu3+) from Polymeters Response International. "The first microprocessor-based meter", using "FFT, rather than 'brute-force' DSP" [1]
I think I read somewhere that Calmu3 (minus the +) lacks CoP5 approval.
It may need calibration periodically, but that's probably up to the supplier.
Serial no: P99A01869 Part no: C3D B D 0 BC 0SJ (3 phase direct, class 1 accuracy, lithium backup, ?)
Interfaces
- Infrared PACT port (this is a standard - possible adapter)
- Serial port ("for PC, modem or PACTLAN")
Software with support
- Principal (DOS) or Ease II (can't get this to run on XP due to .vbx; probably needs 2000; uses stopcopy protection) from PRI
- mv-rs, and possibly other Itron stuff
- Ziphany http://www.ziphany.com/Files/Supported_Meters.pdf

A later model, with overview.
Presumably ex-PRI consultant on Calmu meters
