Operations
Normal Operating Sequence
1. The acremeter may count rotations during drill cali-
bration (and if so, can be useful for calibration).
2. Record the acremeter reading at the start of plant-
ing (and after calibration). The large “12345.6” for-
mat display is the grand total area planted since
meter installation. If the display is blank, see “Dor-
mant Display”.
3. Lower drill and plant. Acremeter counts shaft rota-
tions, calculates acres or hectares, and adds to the
running grand total.
4. During planting (drill lowered and moving forward),
the display blanks (goes dormant), but area tally
continues.
5. When raised for turns, obstructions and transport,
the drill’s ground drive wheel, contact wheel or
clutch disengages the drive shaft, and the meter
counts no additional (non-planting) rotations.
6. Whenever shaft rotation stops, the LCD display acti-
vates after 30 to 60 seconds, and remains visible for
30 to 45 minutes.
7. At the completion of planting, record the final read-
ing of the grand total. If the display goes dormant
before you can read it, see “Dormant Display”.
8. Subtract the reading at Step 2 from the reading at
Step 7 for the total planted in the present session.
Dormant Display
Refer to Figure 3
To conserve power, the LCD display blanks itself most of
the time. If you need to read the display after if has
“timed out” and gone dormant, gently tap or wave a mag-
net at either of the Great Plains logo spots
on the
lower region of the display. Be careful not to scratch the
window.
Great Plains provides a magnet for the acremeter, it is in
the shipping box for the acremeter.
If you are using your own magnet and it does not “wake
up” the acremeter display, try a stronger magnet.
