The 'change the password(s)' and 'select the security level' screens/options
are always protected by the supervisor password, regardless of the security
level selected. This is to ensure that unauthorised personnel cannot change
the security level and password(s) and so lock out the instrument from other
users.
The supervisor password provides access to all password protected
options/screens. That is, if you have selected the 'high' security level and are
prompted to enter the operator password, you can also access the option/
screen by entering the supervisor password.
Password protection can be used to prevent adjustment of the clock by
unauthorised persons, so ensuring the validity of measurement times and the
'time since last calibration' history.
6.3.2 Selecting the security level
As supplied, the security level is set to 'high', the supervisor password is set
to "2000" and the operator password is set to "1000".
Before the instrument is used for sample measurement, we recommend that you
select the security level (low, standard or high: see Section 5.6) most suitable for the
way in which the instrument will be used by you and/or your personnel.
Use the following procedure to select the required security level:
1.
Select
Settings

To change the security level, press the
soft key. You will then be
prompted to enter the supervisor password.

Once the supervisor password has been entered correctly, the security select
screen will be displayed (see Figure 14), with the currently selected security
level highlighted.
