M-FREQ Command
Purpose:
Read metered frequency (F)
Syntax :
M-FREQ[<source>]
Comments: Frequency is measured from A-phase to Neutral on four-wire sensing systems and A-phase
to B-phase on three-wire sensing systems.
Phase = P/X/S for phase/Auxiliary/Slip
M-FREQ Command Example
Read the power system frequency.
>M-FREQ
M-FREQP=58.00Hz; M-FREQX=60.00Hz; M-FREQS=2.00Hz
M-I Command
Purpose:
Read metered current in primary units.
Syntax:
M-I[<phase>]
Comments: phase = A/B/C/N/Q/G or no entry
M-I Command Examples
1.
Read metered current values.
