Smoky flame or poorly adjusted air shutter
Faulty Photocell
Temperature over 165

C) at photocell
For gas flames (Flame Rod):
Ignition interference (A flame signal current difference with the ignition both on
and off greater than 0.5 A indicates the presence of ignition interference)
Insufficient ground (must be at least 4 times the detector area)
Flame lifting off burner head (ground), or not continuously in contact with the
flame rod
Temperature in excess of 600

sequence (
selection can be left out as factory calibration default for countries that
only accept metric units).
Be sure to insert the banana plug type K temperature bead probe Bkp60 with correct
polarities. Banana pins to type K socket adapter Bkb32 (Optional purchase) can
be used to accept other typeK probes using standard miniature plug.
Temperature accuracies assume meter interior has the same temperature of the
ambient (isothermal sta ge) for a correct junction voltage compensation. Allow the
meter and the type K probe set to reach isothermal stage for a significant change of
ambient temperature. It can take up to an hour for changes > 5°C.
Discharge capacitor(s) before making capacitance measurements. Large value
capacitors should be discharged through an appropriate resistance load. Using
Capacitance function in a live circuit will produce false results and may damage the
meter. In many cases the suspected component
(s) must be disconnected from the
circuit to obtain accurate measurement readings.
