PURPOSE
To customize the selection of pressure units that are available for selection from the
[UNIT] function key.

PRINCIPLE
The [UNIT] function key makes available a choice of six default pressure units (US or SI
units depending on whether the PPCK+ has been factory set as US or SI) (see
Section 3.2.2). PPCK+ also supports many commonly used units other than those
included in the default set up. These units can be made available for active selection by
customizing the UNIT function using
[SPECIAL] , <3PresU> . This allows PPCK+ to offer
a very wide selection of units while simplifying day to day operation. The typical user will
customize the
[UNIT] function key to support his/her six most commonly used units.
