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

Software with support

A later model, with overview.

Presumably ex-PRI consultant on Calmu meters
