G. Weigh the truck and load (be sure the driver is included if he was in the truck when it was
weighed the first time). The difference between the starting weight and the ending weight is the
actual amount discharged by the conveyor.
H. To correct the calibration number, use the following formula:
I. Put the mode selector switch in SET-UP and use the INC/DEC switch to change the calibration
number. (REMEMBER, IF YOU ARE IN SPLIT DRIVE, YOU MUST HAVE THE
BOOM
SWITCHES ON.) Switch back to OPERATE and the corrected indicated weight will be dis-
played. If the indicated weight now matches the actual weight, the conveyor is calibrated.
J. Note: If channel C is being used as a liquid control channel, start with the typical flow meter
calibration number for the flow meter installed. Adjust the calibration number according to the
testing and adjustment procedure in Section 6.9. (Remember, channel C Product Density must
be set to 1.0 to use it as a liquid control channel, Section 6.1.2.)
IF IT IS NOT CONVENIENT TO CONDUCT AN ACTUAL CATCH TEST,
FIELD EXPERIENCE WILL ALLOW YOU TO FINE TUNE THE FLOW
METER CALIBRATION NUMBER. IF CHANNEL C IS APPLYING TOO
MUCH, DECREASE THE CALIBRATION NUMBER BY THE SAME
PERCENTAGE AS THE OVER APPLICATION. IF CHANNEL C IS
APPLYING TOO LITTLE (YOU HAVE MATERIAL LEFT OVER) IN-
CREASE THE CALIBRATION NUMBER BY THE SAME PERCENT-
AGE AS THE UNDER APPLICATION.
(INDICATED WEIGHT ÷ ACTUAL WEIGHT) X SPREADER CONSTANT = NEW SPREADER
CONSTANT. If the weight read from the console is greater than the weight actually
measured, the calibration number will increase.
WRITE DOWN THE SPREADER CONSTANTS FOR DIFFERENT MATERIALS AND DIFFER-
ENT GATE SETTINGS. USE THOSE NUMBERS WHENEVER YOU ARE SPREADING THAT
MATERIAL AT THE SAME GATE SETTING.
