Note: This was the electricity meter in our old space at Unit 24, 37 Cremer Street. It is preserved here for historical reasons as this page is probably the most comprehensive documentation of this meter on the internet.

MULTIPLY ALL READINGS BY ONE

Calmu3+ from Polymeters Response International. "The first microprocessor-based meter", which uses "FFT, rather than 'brute-force' DSP" [1]

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

Details

  • 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"). This is apparently not PACT.

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

Source code

Resources

A later model, with a nice overview of available metrics.

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. This seems to be consistent within each value, however.

'N', 's', 'u' or 'x' are slightly special/buggy. If a valid index isn't provided for 'N' or 'x', the meter returns '\xff' with no '\r', so take steps to prevent this. If a valid index isn't provided for 'u', 'U\r' is returned. 's' always seems to return the same value.

Lowercase commands are always inverted and smaller than uppercase, suggesting they're from another perspective. Obviously, units still increase, so 'u' probably just calls 'U', explaining its strange behaviour.

Sampling seems to be live, so sampling more frequently will be more accurate. Due to the baud rate, a sample takes 120-240ms.

Commands

F Frequency "F=50.138\r"
R (Real?) time. "R=15:00:40\r"
S Serial number "SP99A01869\r"
s Meter information "s=", dword 0xa605019e, dword 0, "\r"

Notes

  • V is clearly voltage.
  • I is clearly current.
  • Q is {0, 1}, so clearly power factor.
  • P is I * V, so must be true power.
  • K is P / Q, so must be apparent power.
  • L is I*Q, so "apparent" current.

Memory

This is probably RAM. This MCU is 768 bytes of RAM.
