3.11
3.5.2 Operator Mode
This is used to change information and values. It is accessed via a password. As the analyser
is supplied the password is:
4 5 6 ENTER
The SET and ENTER keys are only used in the OPERATOR mode.
For example to change the Lo Lo alarm setting to 5%:
First enter the password
4 5 6 ENTER
The display will change to
0.00 00
To change the alarm level press
SET ALARM Lo Lo
0
5 ENTER
Alarm Lo Lo
New
value
The display will change to
5.00 41
Once the analyser is in the OPERATOR mode other values may be changed without
re-entering the password. If no key is pressed within 30 seconds the analyser will revert to the
oxygen mode and the password will have to be re-entered. This prevents the analyser being
left in the OPERATOR mode. The analyser can also be made to revert to the oxygen mode by
pressing
SET GAS SAMPLE
9
ENTER
Whilst in the OPERATOR mode information may be displayed without changing it by using the
DISPLAY and ENTER keys in place of SET and ENTER.
