Depending on the number of ignition attempts, the flame can take up to
10 minutes to ignite.
Depending on the length of the combustion gas supply line, it is possi-
ble that not enough combustion gas is available to ignite the flame at
first during the initial start-up of the gas analyzer. In this case, the igni-
tion of the flame must be restarted (see page 277) in the menu
Standby/Restart FID.
The temperature of the flame is displayed in the Raw measured values
auxiliary variables menu option in the Flame parameter; 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.
