2. Lower drill and plant. Acremeter counts shaft
rotations, calculates acres or hectares, and adds to
the running grand total.
3. During planting (drill lowered, moving forward), the
display blanks (goes dormant), but area tally
continues.
4. When raised for turns, obstructions and transport,
the drive wheel stops, and the meter counts no
additional (non-planting) rotations.
5. Whenever shaft rotation stops, the LCD display
activates 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” below.
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 34
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 calibration crank to turn the jackshaft 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 acre for which the meter is factory-programmed.
