RPM4™ OPERATION AND MAINTENANCE MANUAL

PRINCIPLE

The [UNIT] function key makes available a choice of six default pressure units (US or SI units depending on whether the RPM4 has been factory set as US or SI) (see Section 3.3.2). RPM4 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], <6PresU>. This allows RPM4 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 six most commonly used units.

OPERATION

To customize the [UNIT] function key, from the MAIN RUN screen press [SPECIAL], <6PresU>. The display is:

1.Entry field to specify which unit position (1 to 6) of the [UNIT] function key menu is to be changed.

Enter the number of the unit position that you would like to change. The display becomes:

Set up unit #6

Unit#6 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.

The units of measure available are listed in Table 9.

If <4user> is selected, the user unit must be defined. The display is:

1.Entry field.

Define user unit: 1.000000 unit/Pa

Enter the number of user units per Pascal (Pa) in the entry field. Pressing [ENT] defines the user unit and returns to the <Set up unit #n> screen.

The user defined unit label can be customized to any alphanumeric, four character label using the remote command “UDU” (see Section 4.4.4).

See Section 7.2.1 for the pressure unit conversion factors used by RPM4.
