Field Reference Guide—iScan
STEP I. POWER UP SYSTEM
1. Inspect unit for loose or missing
bolts, any obvious problems
2. Clean dried soil and crop residue
from ground-engaging components
3. Lubricate fittings weekly
4. Turn on power; verify red LED is
visible through optical window
PROPER FIELD SETTINGS
All 4 iScan soil engaging components
need to be set level with good soil
contact; set coulter to cut ½" (1 cm)
deeper than other components.
Proper depth of optical sensor is 1.5-3"
(3-6 cm) with good soil contact under
window.

NO COMMUNICATION
1. Check Controller12 V power; use
voltmeter if necessary.
2. Reboot tablet and V-Sense
controller.
3. Check Bluetooth pairing.
Note: iScan can be locked up in storage position if interferes with planting
STEP II. OPEN SOILVIEWER PROGRAM
1. Select iScan module
2. Select file storage location and
name file/field; start new file
3. Verify communication is established
FIELD ADJUSTMENTS
To adjust coulter
depth, loosen front
and rear bolts;
rotate cam to raise
or lower; retighten
bolts.
Set coulter gauge wheel and closing
wheels to maintain depth; CLOSING
WHEELS ARE ELECTRODES; MUST
MAINTAIN GOOD SOIL CONTACT

NOISY OR SPOTTY MAP
1. Adjust depth of iScan components;
make sure all 4 electrodes are
making good contact with moist soil.
2. Check airbag pressure: increase to
75 PSI (520 kPa) max in implement
raised position
3. If optical data shows streaks, check
window for dried mud or cracks
(Refer to Operating Instruction Manual for complete instructions)
STEP III. PERFORM DAILY CHECKS
1. Check airbag: 75 psi (520 kPa)
maximum in planter raised position
2. Perform black-white reference block
test; Check wear plate and window
for excessive wear or damage.
MAP MONITORING
Map should have
pass-to-pass
repeatability with
distinct zones of
contrasting soil.
• Observe any warnings that appear.
• When implement is raised, EC should
be -1; no EC or OM data on turnrows.
• Start new file for each field and each
day; data can be combined later
EC DATA ISSUES
1. If EC isn't -1 when unit raised: Clean
mud from iScan module; check
electrode isolation with ohmmeter
2. If EC map is noisy or readings are
jumpy: check continuity using test
box and ohmmeter
Remember to power 12 V down at end of day!
