USB Detection (7)
A USB symbol will be displayed in the bottom right corner when the USB memory stick is plugged in
(behind 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 Stick function (refer to Section 3.5.1).
3.5 Menus & Screens
The menu system is divided into two sections, the Quick Menu and the Main Menu. The Quick Menu
contains all information and operations necessary during scheduled maintenance visits. The Main
Menu contains all fields that are accessible to users; they provide information on component
failures, 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 machine (e.g. the manual
“Cal. Mode” and” Port” can only be changed when the instrument is out of warm-up).
3.5.1 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
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.
After activating the span calibrate field, a window will open with editable numbers. Change the
numbers to match the concentration of the span gas that the instrument is sampling and select
Accept. The instrument span calibration has now been performed.
Event Log
This field enters a screen with a log of all the events that the instrument has performed. These
events include calibrations, errors, backgrounds and warnings. This log is stored on the removable
USB flash memory.
Instrument
This field allows the instrument to be set to either Online (normal instrument operation) or In
Maintenance. This field is used to change the instrument into In Maintenance when service work is
being performed.
Safely Remove USB
Before removing the USB memory stick, always select this menu item also present in the Service
Menu (refer to Section 3.5.14). Failure to do this may cause corruption of the memory stick.
