calibration or sample gases into the

. Refer to the Caution at the start of
Section 6.

Switch on/set
-up
Note:
When the electrical supply to the
analyser
is switched on, the Alarm LED and the Fault
LED will both go on for 1 second to demonstrate that they are functioning correctly,
and will then go off again.
When you switch on the electrical supply to the analyser, a ‘start
-
up screen’ is first displayed, then the
Measurement screen (Figure

) is displayed.

Selecting the security level and password(s)
You can configure the analyser to provide any of three levels of security:
Security level Function
Low
None of the op�ons/screens are password protected *.
Standard
Some of the op�ons/screens are protected by a supervisor password.
High
Some of the op�ons/screens are protected by a supervisor password and
some o
f the op�ons/screens are protected by an operator password †.
* Except for the ‘change the password(s)’ and ‘select the security level’ op�ons/screens: see notes
below.
† The supervi
sor password can also be used to access op�ons/screens protected by the operator
password: see notes below.
Note:
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
analyser
from other users.
Note:
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
p
assword.
Note:
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.
