Ionisation current.
The minimal ionisation current is 0.9
micro-Amperes DC. Below this current
the burner controller will assume
no flame present. When in normal
operation, the ionisation current wil be
about 1.2 to 1.3 micro-Amperes DC
when only the pilot flame is burning.
(Adjust the main burner pressure to
zero to be able to measure under this
condition) With pilot- and main burner in
operation, the ionisation current will be
about 6.0 and 6.3 micro-Amperes DC.
Ionisation current can be measured by
connecting a universal-meter in series
in the connection to the ionisation
electrode. Make sure to measure in
Direct Current; Alternating Current in fact
gives no information about the system's
behaviour.
