You can set which measurement function values result in a D/A output of -5 V, and which result in a D/A output of
+5 V.
This enables the D/A output to be expanded or reduced for each channel (D/A zoom). For example, if you are
measuring a current that fluctuates between 0.6 A and 0.8 A with a measurement range of 1 A, when the D/A
output range mode is Fixed, the D/A output voltage will fluctuate between 3.0 V and 4.0 V. When you want to
observe the fluctuations more closely, you can use the D/A zoom feature. If you set the D/A output range mode
to Manual and set the minimum value to 0.6 and the maximum value to 0.8, this Instrument will produce –5 V
when the measured current value is 0.6 A and +5 V when the measured current value is 0.8 A.

Maximum (Max) and Minimum (Min) Range Values
When the D/A output range mode is Manual, you can set the maximum (Max) and minimum (Min) values within
the following range.

• The output is 0 V if a measurement function is not selected or if there is no numeric data.
• If a scaling factor such as a VT ratio, CT ratio, or power coefficient is applied to a voltage, current, or power
value and scaling is enabled, this Instrument produces 100% output (5 V) when the scaled measured value
is the same as the scaled rated value (measurement range × scaling factor).
• For Σ functions, this Instrument produces 100% output (5 V) when the measured value is equivalent to the
value that is measured when all of the elements in the group are at their rated values. When the elements
have different scaling factors, this Instrument produces 100% output (5 V) when the scaled measured
values are the same as the scaled rated values (measurement range × scaling factor).
