 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.

<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
