3.4.1 Quick Menu
The Quick Menu contains all the maintenance tools in one easy to use screen. It allows operators to
perform calibrations, check important parameters and review the service history.
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 measurement 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
instrument is sampling and press
Accept .
Event Log This field enters a screen with a log of all the events that the
instrument has performed. These events include errors and
warnings. This log is stored on the removable USB memory stick.
The log is organised by month. When you enter this screen you
will be prompted to enter the month for which you wish to view
events.
Instrument This field allows the instrument to be set to either Online
(normal instrument operation) or In Maintenance (data is
flagged as invalid).
Safely Remove USB Stick Always select this menu item before removing the USB memory
stick or select the same menu item from the
Service Menu (refer
to Section 3.4.12). Failure to do this may cause corruption of the
memory stick.
Instrument Gain This is a multiplication factor which is used to adjust the
concentration measurement to the appropriate level (set by
performing a
Span Calibrate ). This should be recorded after each
calibration in the station log book.
Next Service Due A field that notifies the user when the next instrument service is
due. This value is editable in the Next Service Due field of the
