Manual (Manual range mode)

When the manual range mode is selected, the measurement function display value of D/A
output -5V to +5V can be set arbitrarily. With this setting, the D/A output for each channel can
be enlarged or reduced.
For example, when measuring a current (20A range) that fluctuates between 10A and 12A, if
the range mode of the D/A output is set to fixmode, the D/A output voltage will fluctuate
between 2.5V and 3V. Using the D/A scaling function to observe this fluctuation further. If the
D/A output mode is set to Manual and the Lower value is set to 10 and the Upper value is set
to 12, the instrument will output -5V when the measured current value is 10A and +5V when
the measured current value is 12A.
The output of the fluctuation comparison between Fixmode and Manual mode is shown
below.
