How to Apply a Manual Offset to an Input Signal
If the desired amount of offset is known, select it with the Manual Offset slider.
1. Select an access level of Operator or above.
2. On the Station Manager application Display menu, select Station Setup.
3. On the Station Setup window navigation pane, select the input signal that you want to offset.
4. On the Inputs panel, click the Offset/Zero tab.

Warning:
Immediate and unexpected actuator response is possible when you apply a manual offset to
your system. If the Current Value displayed on the Offset/Zero tab is zero, a manual offset
will cause the actuator to move to the new zero position.
Sudden actuator movement can cause injury and equipment damage.
Never apply a manual offset to a sensor being used by the active control mode while station
power is on.
