A. Use the following switch settings to start the calibration:
Power ON
Mode selector SET-UP
Display Selector L & CHEMICALS, VOL. APPLIED
Product Switch 1, 2 or 3 ON (one at a time)
All booms OFF
TASC displays the current calibration number for the channel selected. Adjust the number using the
INC/DEC switch. Record the number for reference.
B. Divert the output of the selected channel to an appropriate catch container. Place the magnet on the (*)
target on the pump driver module to turn the pump on. Allow to run until the pump is primed and air is
purged from the lines. Remove the magnet to stop the pump.
C. Set the mode selector switch to OPERATE and use the INC/DEC switch to set the display to zero.
D. Empty the catch container and prepare to do the actual catch test. You must pump enough material to give a
good sample but still to be able to measure the collected material very accurately.
E. Set the mode selector back to SET-UP and again place the magnet on the (*) target and allow the pump to
discharge into the catch container. When enough material has been collected, remove the magnet to stop the
pump.
F. Set the mode selector to OPERATE. TASC displays the calculated amount discharged. Measure the actual
amount discharged and correct the calibration number using the following formula:
G. Set the mode selector switch to SET-UP and enter the corrected calibration number using the INC/DEC
switch. (Remember, if the channel is set for split drive, all live booms must be ON to view the calibra-
tion number, turn the booms OFF before proceeding further.) Return to OPERATE and the display
should indicate the actual measured amount collected. That channel is calibrated. Calibrate each channel
independently using this procedure.
2.13.2 CALIBRATING GRANULAR BIN APPLICATORS
The first step in calibrating the feed mechanism of the granular co-applicator bin is to enter the initial calibration
number supplied by the equipment manufacturer. If an initial number is not available, you can estimate an initial
calibration number by the following method.
For U.S. Units: Divide the weight discharged (in pounds) during one revolution of the feed mechanism by the
number of sensor pulses generated during each revolution. Multiply the result by 1,000,000 and divide that result by
the product density (in pounds per FT
3 ). Use this number for the initial calibration.
For metric units: Divide the weight (in kilograms) discharged during one revolution of the feed mechanism by the
number of sensor pulses generated during each revolution. Multiply the result by 3,575,000 and divide that result by
the product density (in kilograms per tenths of a M
3 ). Use this number for the initial calibration.
For Air Max co-applicator bins, use the following initial calibration numbers:
HIGH RATE ROLLER LOW RATE ROLLER
(deep grooves) (shallow grooves)
-800 -400
The minus sign indicates this is a non-peristaltic drive channel.
(MEASURED AMOUNT ÷ INDICATED AMOUNT) X CALIBRATION NUMBER = NEW
CALIBRATION NUMBER. If the amount read from the console is greater than the amount
actually measured, the calibration number will decrease.
