This set of menus is available only on those units
equipped with one of the AO options. Referred to as
“Standard Ranging”, it allows the user to enter the val-
ues for the analog output 0 and 100% based on actual
input. It requires the same calibration setup shown in
Figure 10.
Figure 13 shows the menu.

press SELECT. This will access “SAVE
ZERO”.
2. Press SELECT. The screen will flash the

3. Adjust input to the desired 0% level. The
screen will flash the changing input level.
4. Press SELECT, storing the zero setting in
SPA memory and accessing “SAVE FULL”.
5. Press SELECT again. The screen will
flash the input level.
6. Adjust input to the desired 100% level.
The screen will flash the changing input
level.

or use the arrow keys to access “SAVE
