3. Edit the parameters on the screen for the desired setting.
– PRE WET - If spraying with the pre-wet spray bar, press Y (YES). If
used with the anti-icing boom, press N (NO).
– K-FACTOR (Flowmeter Constant) - Represents the number of
flowmeter pulses generated per gallon (P/GAL) of dispersed liquid
(for pre-wet and anti-icing liquids).
The K-FACTOR number stamped on the flowmeter body is
sufficiently accurate for keyboard entry if the viscosity of the liquid is
near that of water.
If the flowmeter constant is unknown, leave the displayed default
value shown. A corrected value automatically calculates and enters
during LIQUID CALIBRATION.
– SRVO DRV (Servo/Proportional) - If using a servo drive, press Y
(YES). For a proportional valve, select N (NO).
– DRV FREQ (Drive Frequency) - Represents the valve
manufacturer’s suggested drive frequency, as shown on the valve
specification sheet.
– PWM OFFSET - Represents the valve operating range starting
point (position flowmeter begins generating pulses). This constant
