IND780 User’s Guide
access to the entire setup menu, unless the metrology switch is placed in the
approved position.
Maintenance—Access is generally the same as the Administrator level with the
exception of access to metrologically significant areas of the setup.
Supervisor—Access is generally limited to editing tables and setting time and
date.
Operator—One default operator account is provided. Sites with validation
requirements might create many operator accounts, each with a username and
password entry requirement. The Operator-class of security is the most
restrictive, allowing the user to use and view, but not change records within
tables.
If a password has been programmed for the default Administrator username in
Setup, and all other users have a password assigned, a login screen is presented
whenever the Setup softkey is pressed. A valid username and password must be
entered. Depending on the access level of the user logged in, setup screens may
be visible only, or visible and available for modification.
If a login fails, the display exits the login page and returns to the home screen.
Metrology Switch
If the metrology switch (S1) is placed in the approved position (On), changes to
the Scale branch of setup and other metrologically significant areas are not
permitted. Access to the metrology switch may be sealed in conformity with local
regulations in “legal-for-trade” applications. Figure 2-1 shows the location of the
metrology switch, immediately adjacent to the Compact Flash card and PLC
module location.

the first initial is upper-case). For example:
