NOTE
The combustion calorimeter can only be ignited when the door is closed.
The ignition monitoring is configured in this menu.
The following must be observed for this:
Single ignition or interval ignition must be chosen.
Single ignition:
After device start and the flushing time period (10 s), the ignition starts for the max-
imum set ignition duration. This time can turn out to be shorter if the ignition thresh-
old is reached before the ignition duration elapses. If the ignition threshold is not
reached within the specified time, the combustion calorimeter goes to STOP state.
Interval ignition:
After device start and the flushing time period (10 sec), the ignition starts for a
maximum set ignition duration and is repeated after a pause equal to the ignition
duration. This is repeated until the ignition threshold is reached.
The ignition threshold specifies the differential temperature between the cooling air
and flue gas. Default value is 3 °C.
