Fidas24 is ready to measure
after warm-up phase
Depending on the number of ignition attempts, the flame can take up
to 10 minutes to ignite.
Depending on the length of the combustible gas supply line, it is
possible that not enough combustible gas is available to ignite the
flame at first during the initial start-up of the gas analyzer. In this
case, the ignition of the flame must be restarted in the Fidas
Restart menu (see page 115). The temperature of the flame is also
displayed in this menu option; the flame is regarded as "on" when the
flame temperature is at least 30 °C higher than the detector
temperature.
The actual start-up of the gas analyzer is concluded with the ignition
of the flame.
