Acremeter Operation
Refer to Figure 15
The acremeter counts shaft rotations whenever the shaft
is rotating - this is with the drill lowered and in motion or
during crank operation. The meter is programmed to dis-
play rotations as acres or hectares, when using all rows,
factory-specified tires and tire inflations.
Note: Unusual conditions and/or non-standard row
spacings can cause the acremeter tally to vary
from actual acres planted.
Normal Operating Sequence
1. Record the acremeter reading at the start of planting
(and after calibration). The large “12345.6” format
display is the grand total area planted since meter
installation. If the display is blank, see “Dormant Dis-
play” below.
2. Lower drill and plant. Acremeter counts shaft rota-
tions, calculates acres or hectares, and adds to the
running grand total.
3. During planting (drill lowered and moving forward),
the display blanks (goes dormant), but area tally con-
tinues.
4. When raised for turns, obstructions and transport,
the drive wheel stops, and the meter counts no addi-
tional (non-planting) rotations.
5. Whenever shaft rotation stops, the LCD display acti-
vates after 30 to 60 seconds, and remains visible for
30 to 45 minutes.
6. At the completion of planting, record the final reading
or the grand total. If the display goes dormant before
you can read it, see “Dormant Display”.
7. Subtract the reading at Step 1 from the reading at
Step 6 for the total planted in the present session.
Dormant Display
Refer to Figure 16
To conserve power, the LCD display blanks itself most of
the time. If you need to read the display after it has
“timed out” and gone dormant:
• use the left gauge wheel to turn the meter shaft once,
or
• gently tap or wave a magnet at either of the Great
Plains logo spots on the lower region of the display. Be
careful not to scratch the window.
When active the lower left corner displays the revolutions
per area for which the meter is factory-programmed.
