USER HANDBOOK
6.3.1 Timed Mode
If TIMED is selected, and the instrument conguration allows user
selectable barhole sample time, the screen shown in Fig. 6.3 is
displayed. The sample time previously set is displayed.
If the instrument conguration
does not allow user selectable
barhole sample time, the screen
shown in Fig. 6.4 is displayed.
To change the sample time:
• Press the UP or DOWN buttons.
Sample time range = 10 to 300 seconds.
Holding the button will perform a fast ramped change. When
300 is reached, the range rolls over to 10.
To accept:
• Press and hold OK .
When the time is set or has been
pre-selected at 30 seconds
for example, the instrument
performs a purge, as shown
in Fig 6.4.
The minimum purge time is ten (10) seconds, therefore, the ‘stop’
option is not displayed for the rst ten (10) seconds.
Note: The timer starts at 0 and when 999 is reached, the timer
rolls over to 0.
