82 / SYSTEM CALIBRATION
3. Press Function key F6 to access the CALIBRATION MENU screen.
Press the 2 key to select LIQUID for the FLOWMETER CALIBRATION
screen, refer to (Figure 49).
4. Select the liquid material for calibration (key 1 - 4).The words
ENABLED and DISABLED after the selected product have no
significance to the calibration. Figure 39 illustrates the LIQUID 1
CALIBRATION selection. Other selections are equivalent. For
pressure based anti-ice systems, it is necessary to enter a target
pressure. This should be the nozzle manufactures rating pressure,
typically 40 psi (2.75 bar).
Note: If running pressure, make sure booms are drained prior to running
“OFFSET”.
A warning message displays stating STARTING THIS
PROCEDURE WILL CAUSE MATERIAL TO DISPENSE. Ensure all
personnel are clear before starting the next step.
5. In the case when ONLY the liquid channel is propelled by the hydraulic
system, start the engine, keeping the vehicle stationary. Engage the
hydraulic system, and increase engine RPMs to normal operating
range.
6. Press “R” on the keyboard to run the liquid pump and start the
calibration routine. For flowmeter based systems, use the liquid
channel “+/-” switch on the Switch Module, as necessary, to obtain an
adequate discharge rate. The number displayed indicates the
accumulating count from the APR sensor.
7. When a sufficient amount of liquid has been dispensed, press “S” to
stop. For a flowmeter based system, a screen appears showing the
previous K-FACTOR and the sensor counts accumulated during the
current run. For a pressure based system, the previous NZLE CNST
and collection time are displayed. The screen asks for an entry of
gallons before proceeding. Perform the next step while the screen
waits for the results.
8. Weigh the material caught and calculate the amount dispensed in
gallons.
9. Enter that number into the console and press “ENTER”. Press “D”
when finished. The flowmeter constant (K-FACTOR or NZLE CNST) is
now stored and displayed on this screen and on the LIQUID
CONFIGURATION screen for this material.
10. For maximum accuracy, repeat the entire procedure at least three
times. Temporarily write down the resulting K-FACTOR (NZLE CNST)
each time. Average the results and keyboard enter the average as the
final K-FACTOR (NZLE CNST). Then record the K-FACTOR (NZLE
CNST) for this material on the CALIBRATION DATA RECORDS sheets
at the rear of this manual.
11. Repeat this procedure for each liquid material used.
