If problem exists in manual mode, then Tracker is setup
incorrectly or Performance Settings are incorrect.
1. Verify that temperature bails are clean and securely
attached.
2. Verify temperature bail symbol “T” is displayed on
face of Tracker. If not, clean or replace transducer.
3. Check that Trackers are between 14 and 24 inches from
reference.
4. If there are gusty winds, lower Tracker closer to
reference. Approximately 14 to 16 inches.
5. Move Tracker away from gusty heat source, such as
engine fan exhaust.
6. Verify Tracker is not picking up erroneous signals from
undesired reference.
Example: Head of material, end gate, shoulder grade or
material spillage from hopper.
7. If using Stringline, verify line is not bouncing.
8. Check to see if Averaging in Performance Menu is set
too low.
Factory setting is 50.
9. Check that Deadband, in Performance Menu, is not less
than 3mm.
