Measuring Flame Current
When the burner flame is properly adjusted, it will produce a current between 2.5
μ
A and 3.5
μ
A.
Flame current is measured by placing a microamp (not milliamp) meter in series with the sensing
wire on the ignitor.
1.
Place the fryer power switch in the OFF position.
2. Disconnect the sensing wire from one of the burner ignitors and connect it to the positive lead of
the meter. Connect the negative lead of the meter to the terminal from which the sensing wire
was removed.
3. Place the fryer power switch in the ON position to light the burners. After the frypot
temperature reaches 200
°
F (93
°
C), wait at least one minute before checking the reading.
NOTE:
The closer the unit is to normal operating temperature, the more accurate the reading will be.
