
PURPOSE
To customize the selection of pressure units of measure available in the [UNIT] key menu.
 PRINCIPLE
The [UNIT] function key makes available a choice of four default pressure units (psi, MPa,
kPa, bar) (see Section 3.7.3). RPM4-E-DWT 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] , <6Punit> . This allows
RPM4-E-DWT to offer a very wide selection of units while simplifying day to day operation.
The typical user customizes the
[UNIT] function key to support his/her most commonly used
units. Up to six units can be included in the [UNIT] screen.
 OPERATION
To customize the [UNIT] function key, press [SPECIAL] , <6Punit> from the MAIN RUN
screen. The display is:
1. Entry field to specify which unit position (1 to 6) of the [UNIT]
function key menu is to be changed.
Set up unit #5
Enter the number of the unit position that you would
like to change. The display becomes:
Unit#5 1SI 2other
3altitude 4user
Select the desired pressure unit category (SI units include units
based
on SI units such as
mmHg), then select the desired unit from the unit menu. <3altitude> is not available in this
RPM4-E-DWT model.
The units of measure available are listed in Table 7.
