Timers
The timers function enables the operator to set standard purge times and set auto-power off if the
unit is untouched for the period of time specified.
1) Select ‘Key 1 – Timers’ and the following screen is displayed:
Timers
1) Select ‘Key 1’ to edit the purge time. Enter the ‘Pump Running Time’ in seconds; this is the length of
time you wish to run the pump to draw the sample, e.g. key in 030 then press the ‘Enter’ key to
accept.
2) Select ‘Key 2’ to edit the auto power off time. Enter the ‘Auto power off’ in minutes; the instrument
will automatically power off to preserve the battery life after the specified time if no activity has
occurred on the instrument. Press the ‘Enter’ key to accept.
3) Select the soft-key ‘Exit’ key to exit the screen and return to the ‘Operation settings’ menu.
Note: Setting the purge time and auto power off functions to zero, disables the option. It is not
recommended to reduce the purge time to below 30 seconds.
Gas Check
This option displays the ‘Gas Check’ menu and enables the operator to zero and span the gas
channels on the instrument. Historical/previous gas checks data can also be viewed and factory
settings can be restored.
1) Select the ‘Menu’ button on the front of the analyser to display the ‘Device Settings’ menu. Press
the soft key to display ‘Operation Settings’.
