A.3.30 Phase, Return (PHS)
Command:
PHS
Returns the phase angle of Channel 2 relative to Channel 1. Use the #SPH
command to set the phase preference: 0 – 360 or
±
180 degrees, leading
or lagging. In 3-phase mode, returns the average of the individual phase
measurements.
Response: Numeric ASCII string.
A.3.31 Power, Return (PWR)
Command:
#PWR
Returns the active power of Channel 1 and 2 together. Channel 1 must be
set to measure AC voltage and Channel 2 AC current. In 3-phase mode,
it returns the total active power. When “1” precedes the PWR command,
it replaces Power Quantities with Energy Readings.
Response: Numeric ASCII string.
