To access the LEVEL function press [SPECIAL], <5prefs>, <5level>. The display is: Selecting <1change user level> brings up the restriction menu: 1change user level 2edit password Restrictions: 1none 2low 3medium 4high Select a different level or The cursor is on the current restriction level. 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-AD 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 34). 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 choice of units of measure available in the [UNIT] key menus. PRINCIPLE The [UNIT] function key makes available a choice of six default units of measure depending on the active Q-RPT and measurement mode (see Section 3. 3. 2 and Table 9, Table 10). RPM4-AD also supports many commonly used units that are not included in the default set up. These units can be made available for active selection by customizing the UNIT function using [SPECIAL], <6PresU>. [. . . ] The designation of a the Q-RPT with the lower full scale default range in RPM4s with two Q-RPTs. Whether pressure is being measured relative to absolute zero or vacuum (absolute mode) or relative to atmospheric pressure (gauge mode). Measurement mode in which the Q-RPT indicates gauge pressure (difference from atmospheric pressure), in both positive and negative directions (above and below atmosphere). The difference between a Q-RPT reading and the AutoZero reference at the time AutoZ is run. [. . . ]
