Commands Defining Current
CURRENT=n
This command sets the current input to be used. CURRENT=0 selects the internal
current measurement, CURRENT=1 selects an external current:current transducer,
CURRENT=2 selects an external current:voltage transducer. All three phases use the
same setting.
CURRENT?
This command is an interrogative command, returning a single digit (0, 1 or 2) describing
the presently selected current input. The number is the same as described for the
CURRENT=n command.
CURRENT-SCALE[ph]=numeric
This command sets the current input scaling for the specified phase (“ph” is the letter
A
,
B
or
C
) for the presently selected current input. This command should not be used in the
same set of commands as the CURRENT=n command. The numeric may be of any
floating point numeric format and may be of any polarity, and sets the overall
multiplicative scale factor for the selected phase and current input.
CURRENT-SCALE[ph]?
This command is an interrogative command, returning a floating point number indicating
the overall multiplicative scale factor for the specified phase (ph is the letter
A
,
B
or
C
)
and the presently selected current input.
Notes –
•
Harmonic number definitions may now be up to 50 (was previously 40).
•
The “TEXT” and “PCL” portions of the various PRINT commands override the
configured printer type selection for the purposes of that command only.
