8 Modes of operation and operating

For an illustration of the method of operation see Chapter 15 “Practical examples”.

8.6.2 Display

The balance display has two lines (1 and 2).

The upper display-line (1) includes the 8-figure measurement display (3) as well as various symbols (4).

The lower line (2) serves as a 20-character info-line in connection with the cursor keys for controlling the
working programs.

8.7

Password protection of the menus

The two main menus of the balance can be protected by a freely selectable, four-figure password against un-
intentional changes.

• With password protection deactivated, any operator can change the balance configuration and application

menus.

• With “standard” password protection activated, only the configuration menu is protected against uninten-

tional changes.

• With “high” password protection activated, both the configuration menu and the application menu are pro-

tected against unintentional changes. Only after entering the correct, four-figure password can changes be
made to the configuration menu and the application menu.

8.8

Anti-theft encoding

The balance can be protected against theft by a freely selectable, four-figure numerical code:

«0/T»

• Initiate Tare Function and/or Calibration Function

REF

• Run application (see Chapter 10 “Working with the

application menu”)

PRINT

• Start print function
• Exit the menu

NOTE

For the operation of the

«0/T»

and «

PRINT

» see Chapter 13 “Special operating keys”.

NOTE

The password protection is deactivated at the works.

The

pre-programed password

set in the works is:

7 9 1 4

This password is the same for all balances and is always valid, in parallel with a self-selected password.

Make a note of your

personal password
