AIR PRESSURE SWITCH
Regulate the air pressure switch after first carrying out all the other
burner adjustments with the air pressure switch adjusted to the start
of the scale. With the burner operating at low flow rate (1
slowly turn the central screw clockwise until the burner locks out.
Then give the screw a half-turn anti-clockwise and repeat burner
start-up to check for proper operation. If the burner locks out again
give the screw another half-turn.
iOnisaTiOn CUrrenT
The minimum current needed to run the apparatus is 3µA. The
burner provides a significantly higher current and therefore does not
normally require any checks at all. Should, however, the ionisation
current need to be measured, a microammeter must be connected
in series to the ionisation electrode lead by opening the connector
"C" as illustrated in the figure.
