Revision as of 16:56, 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.

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, ?)

Interfaces

Software with support


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.

Commands

F Frequency, updated per sample "F=50.138\r"
N Switch protocol? ff
R (Real?) time "R=15:00:40\r"
S Serial number (presumably "=" doesn't fit) "SP99A01869\r"
s ? "s=", dword 0xa605019e, dword 0, "\r"
u (probably unimplemented) "U\r"
x Switch protocol? ff
