Since the Control Console uses “ nonvolatile memory”
for storing the constants, it is unlikely that it will be
necessary to reenter the calibration constants. How-
ever, constants have been known to be distorted as a
result of electromagnetic interference. For this reason,
MID-TECH strongly recommends recording the
current calibration numbers in a convenient location
and checking these values daily, before operating the
sprayer. The last page of this manual provides space
for recording the constants for your machine.

HEEL SENSOR: Check the sensor fre-
quently for loose or bent parts. Repair or
replace any damaged parts immediately and
recalibrate the sensor (Refer to page 2-5, Distance
Calibration Procedure).
RADAR SENSOR: Check the sensor frequently to
ensure that the face of the sensor is relatively clean (no
dirt build up) and that the mounting bracket and
hardware is tight and has not shifted in position. The
sensor can be cleaned using a damp cloth. If it is
suspected that the radar sensor mounting position has
shifted, the mounting bracket must be tightened and
the sensor recalibrated. (Refer to page 2-5, Distance
Calibration Procedure)
Flow Sensor
T
he flow sensor should be inspected periodically
to ensure that there are no leaks around the
fittings. At the end of the day, care should be
taken to thoroughly flush the flow sensor with clean
water. ALWAYS VERIFY THAT WATER OR
SEDIMENT IS NOT TRAPPED IN THE FLOW
SENSOR, PARTICULARLY IN COLD
WEATHER, AS DAMAGE TO THE MECHA-
NISM MAY OCCUR.
The impeller type flow meters supplied by MID-TECH
are inherently rugged. However, continued use
eventually wears the internal bearings and shafts
causing the meter to be inaccurate. Replacement kits

WARNING: Always
disconnect all MID-
TECH power cables, at
the battery, when welding
on the sprayer. Serious
damage can result if left
connected during these
times.
WARNING: Follow all
manufacturer’s safety
instructions when working
on and around the radar
unit.
