'''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.'''


I think I read somewhere that Calmu3 (minus the +) lacks CoP5 approval, but the picture in the manual shows the same as ours.

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

== 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.
