Time
[Backgrounds]
Edit and display the time that the next background will run. The
time is set using a 24 hour clock.
Repeat
[Backgrounds]
Defines an interval value for the repeat of the background based
on the
Units selected. This field indicates the delay period; once
the specified amount of time has lapsed the background will
automatically run again. The user can edit this field but some
restriction apply depending on the
Units selected. Default is “1”.
Units
[Backgrounds]
This is where the user can define the type of units for the Repeat
delay period. For example: A Repeat of “ 1 ” and Units of “ Days”
means that a calibration will automatically run every day at the
defined time. Default is “Days”

Calibration Menu
Calibrating the instrument should be done with care (refer to Section 5 before using these menus).
Cal. Type Depending on the selection in this field, a number of extra menu

Time when the calibration will begin

Check only or automatic compensation
Timed calibration with span compensation enabled does not fulfil

Manual mode allows the user to choose the type of calibration
they wish to perform and will open the appropriate valves in
preparation for the user to perform a manual calibration. The
setup used will depend on the
Cal. Mode selected.
Manual mode is set as default.
Zero Source Select whether the instrument will sample from the external
calibration port or from the internal zero source when zero gas is
requested.
Cycle Time The duration of each Cal. Mode (span and zero) when performing
Cycle Mode (refer to Section 3.4.10.1) or Cal. Type is set to Timed
(refer to Section 3.4.10.2).
Span Calibrate NO2 This field is used to perform a span calibration and should be only
used when a known concentration of span gas is running through
the reaction cell and the reading is stable.
Activating the span calibrate field for a named gas will open a
dialog box. Enter the concentration of the span gas that the
