Time and Date (5)
The time and date are displayed in between the menu buttons at the bottom of the screen.
Concentration Units (6)
The instrument units are displayed in the bottom right hand corner of the display.
USB Detection (7)
A USB symbol will be displayed in the bottom right corner when the USB memory stick is plugged in
(the USB socket is behind the front panel). If the USB symbol is not shown, the USB memory stick
should be inserted. Underneath the USB symbol arrows may be displayed which indicates data
transfer. The USB memory stick must not be removed whilst the arrows are visible.
Note: To safely remove the USB memory stick, navigate to the Quick Menu and use the Safely
Remove USB Memory Stick function (refer to Section 3.4.1).
3.4 Menus & Screens
The menu system is divided into two sections, the Quick Menu and the Main Menu selectable from
the Home Screen. The Quick Menu contains all information and operations necessary during
scheduled maintenance visits. The Main Menu contains all fields that are accessible to users. It
provides information on component failures and measurement parameters as well as editable fields
and test procedures.
In general, editable parameters are displayed in bold font. Non-editable information is displayed in a
thin font. Some parameters may become editable based on the state of the instrument.
For example, the manual calibration type and mode can only be changed when the instrument has
finished the warm-up process.
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.
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.
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.
This field allows the instrument to be set to either Online (normal
instrument operation) or In Maintenance (data is flagged as invalid).
