[. . . ] Low security is designed to protect the specific metrological information and SYSTEM DIAGNOSTIC AND MAINTENANCE functions of the system against accidental alteration. It is intended for an advanced operator performing many different tasks. Medium security is designed to protect specific metrological information in the system and to assure that the PPC3 is operated using consistent operational parameters. It is intended to minimize operator choices, for example to perform repeated identical calibrations under consistent conditions. PPC3 is delivered with the security level set at low to avoid inadvertent altering of critical internal settings but with access to changing security levels unrestricted. It is recommended that the low security level be maintained at all times. If there is a risk of unauthorized changing of the security level, changing authority should be password protected (see OPERATION of this section). The security levels are structured to support typical levels of operation as shown in Table 12. Specifically, the security levels prevent execution of the functions accessed by the key strokes marked by "·": Low Medium High Page 71 © 2002-2007 DH Instruments, a Fluke Company PPC3TM OPERATION AND MAINTENANCE MANUAL Table 12.

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 PPC3 password entry screen appears. The user must enter the user defined password or the factory secondary password to proceed further: PPC3 SNnnnn-xx Password: pppppp The first field, <nnnn>, is the serial number of the PPC3, 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 difference between a Q-RPT reading and the AutoZero reference at the time AutoZ is run. Used by the AutoZ function when Auto Z is ON to compensate Q-RPT readings for changes in zero over time. Value indicated by the device against which the Q-RPT is zeroed by AutoZ. Pressure adder, used to offset a Q-RPT, utility sensor or barometer to calibrate it. [. . . ]
