 OPERATION
RPM4 is delivered with no active password and access to the User Level menu is
open. The user level is set to <1Low>. User levels can be changed freely until a
password has been created.
To access the LEVEL function
press [SPECIAL], <5prefs>, <5level>.
The display is:
1change user level
2edit password
Selecting <1change user level> brings
up the restriction menu: Restrictions: 1none
2low 3medium 4high
The cursor is on the current restriction level. Select a different level or
or [ESC] back to the MAIN RUN screen.
If no password is active, selecting
<2edit password> displays the user
password and allows it to be edited.
Password: pppppp
0 disables password
Once a password has been entered, the user level cannot be changed without
reentering the password.
Passwords can be up to six numbers in length and cannot start with a zero.
If <0> is entered, the password is made inactive and the user will not be required
to enter a password to access the user level menu. This condition, with a
security level of <2low>, is the factory default.
If there is an active password, the
RPM4 password entry screen appears.
The user must enter the user defined
password or the factory secondary
password to proceed further:
RPM4 SNnnnn-xx
Password: pppppp
The first field, <nnnn>, is the serial number of the RPM4, followed by a second field,
<xx>, that represents the number of times that a secondary password has been
used. The second field, <xx>, increments each time a secondary password is
used. The third field, <pppppp> is for user entry of the normal password.
The factory secondary password is available in case the user’s password has
been misplaced or forgotten. It can be obtained by contacting a DHI Authorized
Service Center (see Table 23). The factory secondary password is different for all
RPM4’s and changes each time it is used.
3.5.6 <6PUNIT>
 PURPOSE
To customize the selection of pressure units of measure that are 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 3.3.2). 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
