Operations
Factory Installed
The DataTrac acremeter is factory installed on new units.
The meter is supplied with a decal located on its side
indicating the number of programmed wheel revolutions.
Reading the Display
The numbers automatically orient to read upright.
The acremeter always shows “REV” on the face of the
display. The meter is programmed to count acres if the
drill is for domestic use and is programmed for hectares
if the drill is for export use.
Normal Operating Sequence
Refer to Figure 2
To display the number of revolutions per acre or hectare
programmed into the meter simply cover the round bump
on the face of the unit (light sensor)
with the palm of
your hand and leave it there for at least
1 ⁄2 second before
removing it. A screen that shows “rEV ###” will be
displayed. The ### is the number of revolutions that is
programmed into the unit.
1. The acremeter may count rotations during drill
calibration (and if so, can be useful for calibration).
2. Record the acremeter reading at the start of planting
(and after calibration). The large “123456” format
display is the grand total area planted since meter
installation.
Note: On 3P500/3P500V, 3P605NT, 605NT, 3P606NT
and 606NT drills intended for measurements in
hectares, it is necessary to multiply the “REV”
display number times 10 to get the true hectare
reading.
3. Lower drill and plant. The acremeter counts shaft
rotations, calculates acres or hectares, and adds to
the running grand total.
4. 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.
5. At the completion of planting, record the final reading
of the grand total.
6. Subtract the reading at Step 2 from the reading at
Step 5 for the total planted in the present session.
Dormant Display
If the display is totally blank and never displays anything,
the battery may be dead. Expected life is 5 to 10 years.
The battery is not user-replaceable.
