The available analog output options are described in Table 13.

Zero scale
Full scale
When you select an output parameter for the analog output channel,
the default engineering scales are set automatically. They correspond
to the maximum available scales. If the parameter actually covers a
lower range, you can change the scales to provide a better resolution
on an analog output.
Scaling Non-Directional Analog Outputs
For non-directional analog outputs with a 0-1mA, 0-20mA or 4-20mA
current option, you can change both zero and full engineering scales
for any parameter. The engineering scale need not be symmetrical.
Scaling Directional Power Factor
The engineering scale for the signed power factor emulates analog
power factor meters.
The power factor scale is -0 to +0 and is symmetrical with regard to
1.000 (-1.000  +1.000). The negative power factor is scaled as
-1.000 minus the measured value, and non-negative power factor is
scaled as +1.000 minus the measured value. To define the entire
power factor range from -0 to +0, the default scales are specified as -
0.000 to 0.000.
Scaling ±1mA Analog Outputs
Programming engineering scales for directional ±1mA analog outputs
depends on whether the output parameter represents unsigned (as
volts and amps) or signed (as powers and power factor) values.
For an unsigned output value, you can change both zero and full
engineering scales.
For a signed (directional) value, you should only provide the
engineering scale for the +1 mA output current.
The engineering scale for the 0 mA output current is always equal to
zero for all values except the signed power factor, for which it is set to
1.000 (see Scaling Directional Power Factor
Range
The analog output type. When connected
to the meter, shows the actual AO type
received from the device. When working
off-line, select the analog output option
corresponding to your analog module.
Selects the measured parameter to be
transmitted through the analog output
channel.
Defines the low engineering scale (in
primary units) for the analog output
corresponding to a lowest (zero) output
current (0 or 4 mA)
Defines the high engineering scale (in
primary units) for the analog output
corresponding to a highest output current
(1 or 20 mA)
above).
