The ionization current is checked by inserting a microammeter with
an end scale of 50 µA (d.c.) in series with the ionization probe.
A faulty position of the electrode can lead to a reduction in the
24
ionization current and cause a safety shut off of the burner due to
a flame detection failure. In this case, check the position of the
electrode, its electric connection and the earthing of the burner.
The ionization current is normally > 20 µA.
