Revision as of 16:59, 6 November 2010

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, but the picture in the manual shows the same as ours.

It may need calibration periodically, but that's probably up to the supplier.

Details

Serial no: P99A01869
Part no: C3DBD0BC0SJ (3 phase direct, class 1 accuracy, lithium backup, C?)

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

Resources

A later model, with overview.

Presumably ex-PRI consultant on Calmu meters

Serial protocol

1200bps ASCII, \r terminated

Equals symbols are shown on some variables, but presumably wouldn't fit for many.

Once a 'N', 's', 'u' or 'x' are matched, all the remainder of the line is ignored. This suggests they might be for switching to a different protocol, or buggy code. 'u' is definitely buggy.
