Viewing Or Changing Security Settings - GE PM880 Operations & Installation Manual

Viewing or Changing Security Settings

To guard against accidental or intentional tampering, the PM880
includes a password-based security system. The system has three
security levels:
•
The User level allows access to the display and non-critical
meter settings (such as resetting the clock). However, this
level offers no access to probe or calibration data.
•
The Operator level allows access to most meter settings.
Operators can commission the PM880, enter or edit probe
and calibration data, and manage and delete files.
•
The Service level provides access to all meter settings, and
is available only to GE Panametrics representatives and
authorized service agents.
Individual passcodes protect the three security levels; they consist
of numbers only, and can range from one to eight digits. The
passcode file is not accessible in any way. It does not appear in
the Drive Manager, and cannot be transmitted between the
PM880 and a PC.
The backup battery maintains the file system, so that if the battery
fails or the drive is erased, the passcodes will revert to the default
values. For both the User and Operator level, the default code is
2719.
The PM880 maintains a record of the current security level. If a
user attempts to access a menu that requires a higher security
level, a screen (shown in Figure 8-18 on the next page) prompts
for the appropriate passcode, which must be at the appropriate (or
higher) level. Enter the desired passcode and press
(For example, if the menu requires the Operator passcode, an
operator can enter either the Operator or Service passcode.
However, the PM880 will automatically change the security level
to that of the passcode entered, where it remains until the operator
modifies the level.)
