Archive:CALMU3

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

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
