It is possible to set the signal value for 0% output and for 100% output so as to out- put only a portion of the entire range.
Example:
Range from 0 to 1000 ppm
0% value to be 400 ppm, 100% value to be 700 ppm.
Analog output normally: 0V = 0 ppm, 10v = 1000 ppm
After changing the output scaling: 0V = 400 ppm, 10V = 700 ppm
Change to the “Signal value for 0% out- put:” line and adjust the value to 400. Then change to the “Signal value for 100% output:” line and adjust the value to 700.
NOTE:
If the measurement range is changed, the settings done in this menu will re- vert back to the standard values of the range. The output values can be changed permanently in the menu “Begin and End of Ranges.” See sec- tion 0.

Enable this option to hold the analog out- put to the last value during calibration.
Pressing the F5 (More…) key changes to the submenus “Output Signal if Assigned Module Fails” and “Fine Adjustment.”
The signal range of the analog output should not be less than the smallest range of the channel. Otherwise the
