IONIZATION CURRENT
The ionization current is checked by inserting a
microammeter with an end of scale of 50 µA (d.c.)
min. 6 μA
in series with the ionization probe.

A faulty position of the electrode can lead to a
reduction in the ionization current and cause a

tion failure. In this case, check the position of the

50 μA end of scale
electrode, its electric connection and the earthing
of the burner. The ionization current is normally > 20 µA.
