Explanation
• D/A Zoom
The D/A output can be magnified or reduced for each channel in manual range mode
by setting the D/A output range. For example, if a current varying in the range of
0.6 A to 0.8 A is measured at the 1-A range and the D/A output is set to fixed range
mode, the D/A output voltage varies between 3.0 V and 4.0 V. If you wish to magnify
this variation, you can use the D/A zoom function. In this example, set the D/A output
to manual range mode and set the maximum and minimum values to 0.6 and 0.8,
respectively. Then, the D/A output delivers –5 V and +5 V when the measured current
is 0.6 A and 0.8 A, respectively.
• Selecting the D/A Output Range Mode
Select either mode from below.
• Manual
The displayed values of the measurement functions corresponding to the D/A
output of –5 V and +5 V can be set arbitrarily.
• Fixed
Outputs +5 V when the rated value of each measurement function is applied. For
details, see section 3.2.
• Setting the Maximum and Minimum Values for Manual Range Mode
The maximum and minimum values can be set in the range of –9.999E+30 to
9.999E+30.
