4-3-1. Passcode protection
In Service Code 52, EXA users can set passcode protection for each one of the three
operating levels, or for any one or two of the three levels. This procedure should be
completed after the initial commissioning (setup) of the instrument. The passcodes
should then be recorded safely for future reference.
When passcodes have been set, the following additional steps are introduced to the
configuration and programming operations:
Maintenance
Press MODE key. The display shows 000 and *PASS*
Enter a 3-digit passcode as set in Service Code 52 to obtain access to the Maintenance
Mode
Commissioning
Press * key. The display shows 000 and *PASS*
Enter a 3-digit passcode as set in Service Code 52 to obtain access to the
Commissioning Mode.
Service
From the commissioning menu, select *Service by pressing YES key. The display shows
000 and *PASS*
Enter a 3-digit passcode as set in Service Code 52 to obtain access to the Service Mode.
NOTE
See Service Code 52 for the setting of passcodes.

The next page shows the sequence of button presses and screens displayed when
working in standard configurations.
More or less options will be made available by the configuration of some service codes,

The following deviations are possible:
Items marked are omitted when switched off in commissioning mode
and/or service code 51.
Temperature compensation will be displayed dependent on chosen
compensation method: NaCl, TC 2.1 or matrix.
DISP.2 only appears if mA2 is configured for a 2nd (different)
temperature compensation or if % by weight.2 is enabled in code 55.
W/W % only appears if switched on in service code 55.
A raw value without temperature compensation will be played on
DISP if USP setting is enabled in service code 57.
