Draft Zero: The Draft Sensor is standard on the Firetron FT-1200-1 and FT-1300-1. The Draft sen-
sor is pre-calibrated at the factory. This menu option is used where the sensor requires re-calibration.
Draft Zero is a measure of ambient air pressure, with an output displayed in Volts. For details on how
to complete a Draft calibration refer to Section 6.6, Calibrating the Draft Sensor.
Draft Span: The Draft Sensor is standard on the Firetron 1000 Series. A Draft Span calibration
involves the use of a monometer and squeeze bulb. Refer to Section 6.6, Calibrating the Draft Sensor.
A differential pressure reading will be made (FT1200-1, FT1300-1 only).
