Note: Pressing and holding the power button for ~20s resets the analyser.
6.5 Changing between parameters
By default, the instrument displays the ‘Main Gas Read Screen’ (for gas measurement).
The instrument will return to this screen after power on or when returning from the
menus. The ‘Scroll’ keys can be used to switch to another measurement screen.
6.6 Entering data
During normal operation the operator may be prompted to enter data or information via
the keypad, i.e. entering an ID code or setting an alarm level.
When entering data into the instrument all fields are fixed format and are populated from
the left.
Text:
Entering text uses similar multi-tap functionality as a mobile phone. Key the
numeric/alpha key pad the required number of times to select the appropriate letter. To
key numeric data continue to press the numeric/alpha key until the required number is
displayed.
Numeric data:
To enter a new date 09/11/11 the operator would type in 091111 using the numeric
keypad in the following sequence:-
* 0_/__/__
* 09/__/__
* 09/1_/__
* 09/11/__
* 09/11/1_
* 09/11/11
Press the ‘Enter’ key to confirm/accept data keyed.
Any mistakes can be corrected using the soft-key ‘Delete’ which will delete the last digit
typed. Alternatively, the sequence can be retyped before the ‘Enter’ key is pressed and
the existing numbers will be pushed off the screen.
Note: The instrument will not allow invalid data to be entered; this should be deleted
and re-entered.
