the Deviation DISPLAY active using the entered target value.
The target value is the value from which deviations (D) are measured by the
Deviation DISPLAY following:

With the Deviation DISPLAY active the main run screen is:
1. Deviation of current pressure from the target
value.

Pressing [ENT] from the main run screen when the Deviation DISPLAY is
active goes directly to the Target editing screen. This allows the target
value to be changed without going through the DISPLAY menu.
If the pressure measurement unit or mode is changed while the Deviation
DISPLAY is active the target value remains at the same numerical value.
It is NOT converted.
To go to a DISPLAY other than Deviation, press [DISPLAY] and make a new
DISPLAY choice (see Section 3.3.6).
