NORAC CALIBRATION
Calibrating the Norac sensors is necessary to
maintain an accurate working height. Detailed instruc-
tions can be found in the Norac operating manual.
If you continue to have problems with your sys-
tems, contact Hagie Customer Service for assistance.
Calibrating the Norac Sensors
1. Unfold the booms into spray position. Make
sure that the sensors are over bare soil or
gravel– do not conduct this calibration over
standing crop or tall grass.
2. Position the boom at normal working height.
3. Use a tape measure to measure the distance
from the bottom of the spray nozzle closest to
the sensor to the ground. Round to the near-
est half inch.
4. On the console, get to the main prompt
“LOht” as described in the Norac manual.
5. If the height displayed is not the same as the
measurement you just took, adjust it using
the “+/-” switch.
6. Repeat steps 3 though 5 fro each of the sen-
sors on the boom.
7. Return to the normal operating screen by tog-
gling the SETUP (NO) switch and holding it
for two seconds.
