Meter Calibration
Meter calibration is performed to adjust each meter to release an accurate insecticide
rate. The meter calibration routine must be performed on all meters at the beginning of
each season. In addition, any time a replacement meter is installed, that row must be
re-configured and its new meter calibrated. For best results, growers should recali-
brate after planting 150 acres and/or when application rates are not accurate.
Pre-calibration Instructions:
Person conducting meter calibrations must insure that proper safety
equipment is used during calibrations; see product label for details.
1. Prior to meter calibration, run each meter in the Operate mode for a minimum of
fifteen (15) minutes with the tractor running. Meters may be run without chemical
during the war-up period.
a. To do this in the shop set the speed mode to fixed, (refer to section D).
Select operate on the main screen of the controller and set the controller
to run.
b. Trip the lift switch to allow the meters to run.
c. This will also test the flow sensors on each meter.
2.
Confirm that each base container is a minimum of 2/3 full of chemical. To fill,
place a loaded transfer container on each base container and open valves.
Preliminary Steps
1. Number calibration bottles to correspond with the number of planter rows.
2. Confirm that the scale used for weighing the catches is set to weigh grams and
placed on a flat surface located out of the wind for proper measuring.
3. Measure and record the tare (empty) weight of the empty catch bottle or apply
tape to the calibration bottles to make the weight of each bottle match the weight
of the heaviest one.
a. Record the tare weight.
4. Install a catch bottle under each meter discharge opening, matching the bottle
number with the corresponding row number as configured in the controller.
Position bottles so that bottle cap hinges are not damaged during installation. On
John Deere planters with row mount brackets you will need to remove the bottle
caps to allow them to fit over the meter discharge opening.
