3. First time use and general operation

3.1 Preparation for first time use

Before using the measuring device, the integrity of all components must be checked, e.g.:
Device exhibits no visible damage
−
No condensed water in the gas preconditioner
−
The gas preconditioner filter is clean
−
Gas hoses without defects
−
Visual inspection of the probe
−
Connect the quick-release hose coupling of the flue gas probe into the gas inlet G of the
measuring device and the jack plug of the flue gas probe in the temperature input T of the
measuring device. Ensure before each measurement that a clean filter is inserted in the gas
preconditioner!
Only turn the FG4500 on, if the flue gas probe is located in fresh air. The null signals of the
sensors are matched with the fresh air.

3.1.1 Before each measurement

The air-tightness of the gas path can be tested easily: Close the gas inlet of the probe with
the round cap. If the gas path is not leaking, the pump should now deliver more power. The
sound of the pump changes accordingly. If no change occurs, then the gas path must be
checked with a gas flow meter.

3.1.2 Touchscreen

The FG4500 is operated with a touch-sensitive display (capacitive touch screen). You can
perform the tap and swipe functions on the screen with your finger or other leading input
devices. Ballpoint pens, pencils and the like are not suitable.
Since the display is equipped with a capacitive touch screen, the operation works with light
touches - without special finger pressure.
Menus and lists can be moved up and down by pan/down (swipe) gestures.
Menus and list positions are highlighted by tapping. The selected position is activated via
the Selection button or by tapping it again.
Touching the display with sharp or pointed objects can lead to the destruction of the
display.
