The respective output point values of the channels are displayed.
The outputs allocated to the channels are as follows:
Tip
For the terminal block output, see the rear panel signal table at the end of this document.
Press a point value button, and the button will be highlighted.
In this state, the following buttons allow you to perform the following operations.

[  ]: Increases the point value for the selected channel. A 10-point increment increases the
output about 3 mV.
[  ]: Decreases the point value for the selected channel. A 10-point decrement decreases
the output about 3 mV.
