Tools Needed to Install Speed-O-Meter
• Screwdrivers and Nutdriver
• Electric Drill and Bits • Pliers
• Tape Measure
Installation
Required Tools
Installation of your SPEEDOMETER is basically a three-step
procedure. Each installation will vary somewhat, depending
on your type of equipment. Allowances for these differences
have been made through the design of flexible mounting
brackets and extra hardware.
Mounting the Display Console
Select a mounting location which seems most workable,
and best fits your needs. It should be convenient to reach
and highly visible to the operator. DO NOT INSTALL IN
A POSITION THAT OBSTRUCTS THE VIEW OF THE ROAD
OR WORK AREA. Whenever possible, avoid locations that
expose the console to direct sunlight, high temperature,
strong chemicals or rain.
Place the mounting bracket in the selected location, mark
holes, drill 1/4” (7mm) holes and mount bracket with bolts,
lockwashers and nuts provided. (Use self-tapping screws if
not practical to use bolts.) See Illustration 1.
Put rubber washers on carriage bolts and put the bolts
through the bracket holes from the inside out. Loosely
attach the mount knobs onto the bolts. Place console over
carriage bolt heads and tighten knobs to secure the console.
See Illustration 2.
Note: Some systems may use two “L” brackets in place of
the “U” bracket for console mounting.

Electrical Installation
Illustration 3
The SPEEDOMETER must be connected to a 12-volt DC
electrical system. Using your test light, locate a terminal or
wire connected to your ignition switch which is “hot” when
the ignition is turned on and “dead” when the ignition is off.
Locate the power cable on the main wiring harness. Connect
the RED wire to the contact point you have located. Attach
the BLACK wire (ground) to a screw or bolt on the equipment
frame. See Illustration 3. Be sure there is a good metal-to-
metal contact. The terminal connectors have been supplied
for your convenience. You may wish to substitute other
types of connectors or make direct solder connection. In
routing cable to console, avoid areas where the cable may be
subjected to abrasion or excessive heat.
Locate the single BLUE wire supplied with the kit to make a
ground wire. Crimp a female spade terminal on one end and
a ring terminal on the other end. Attach the spade terminal
end of the BLUE wire to the mating spade terminal on the
back of the console. Attach the ring terminal end of the BLUE
wire to a screw or a bolt on the equipment frame. Be sure
there is good metal-to-metal contact.
Your SPEEDOMETER is equipped with an advanced
electronic memory which does not require a constant supply
of power to retain daily totals or calibration values. The
advantage with this type of memory is that it conserves
battery power and will not discharge the vehicle’s battery
when equipment is not is use.
NOTE: For negative ground systems ONLY.

Speed Sensor Installation
PLEASE NOTE: If you have purchased an Astro GPS Speed
Sensor or a Vansco Radar Speed Sensor, disregard the
following section on magnetic speed sensors and install
the speed sensor as described in the instructions included
with the unit. See Appendix for adapter cables to connect
to some radars.
Locations where the sensor may be installed:
1. Non-driven wheel on tractor, vehicle or implement. This
is less susceptible to error resulting from wheel slip.
2. Tractor, vehicle or planter drive shaft. This type of
mounting is recommended for trucks, four-wheel drive
tractors or other equipment that has poor or no access
to a non-driven wheel.

Please read the following information about magnet spacing
and polarity.
The number of magnets that must be used depends on
the size of your tire and where you mount the sensor. On
tractor or implement wheels the general rule of thumb is one
magnet for each wheel bolt (minimum of two, and always an
even number). For drive shafts or small wheels (ATV’s), two
magnets are usually adequate.
Some installations may require that more than two magnets
be installed. To determine the number of magnets required,
measure the distance traveled of one revolution of the
sensor equipped wheel in inches (centimeters).
See the following tables to find the minimum number of
magnets required (always an even number)
Attaching Magnets to Hub
The magnets are attached to a wheel hub or drive shaft and
the speed sensor is mounted directly over the magnet. When
the wheel or drive shaft begins turning, a speed impulse is
sent to the FlowTrak II console every time a magnet passes
by the tip of the speed sensor. For the speed sensor to
operate properly, the spacing between the magnets and
the tip of the sensor must always remain constant. Before
permanently mounting any parts, be sure that the location
you have selected will meet the requirements shown in
Illustration 6.
NOTE: Observe magnet polarities (see previous section).

NOTE: Magnets may be attached mechanically or adhered
with epoxy or other high quality adhesive. When using
adhesive, thoroughly clean the area of dirt and oil.
The magnets provided by Micro-Trak are marked with a
punched dashed line on the SOUTH pole side of the magnet.
See Illustration 4.
Always use an even number of magnets, and always alternate
the polarities of the magnets as you go around the wheel
hub or drive shaft.
To install, mount the first magnet with the SOUTH pole side
(dashed line) facing toward the hub or shaft. Mount the
second magnet with the NORTH pole side facing toward the
hub or shaft. See Illustration 5.
For proper operation, the magnets must be evenly spaced
around the wheel or drive shaft. The magnets must be at
least 1” apart. See Illustration 5A.

Refer to the following diagrams for specific mounting
instructions. Magnets may be attached mechanically as
shown or adhered with epoxy or other high quality adhesive.
When using adhesive, thoroughly clean the area of dirt
and oil. With either method of attachment, wrapping the
magnets with a layer of electrical tape is recommended to
provide additional protection from field debris.
Two mounting examples are illustrated.
1. Using one cable tie (ribbed side down) secure two
magnets to the wheel hub so they are exactly opposite
each other. Alternate the magnets’ polarities. See page 8
for proper procedure.
2. Cut and bend sensor mounting bracket as needed and
rigidly mount. See Illustration 7.
3. Insert sensor, adjust spacing and secure with 3/8” locking
nuts.
NOTE: Observe magnet polarities (see page 8).
CAUTION: Make sure valve stem cannot make contact with

Speed Sensor Mounting on Drive Shaft
Determine the best location for the magnets on drive shaft
according to which is the most practical spot to attach sensor
mounting bracket. This position should be no more than 12”
(.30 meters) behind the front U-joint. For best results, mount
“L” bracket to transmission and mount magnets on drive
shaft as close to transmission as possible. This will ensure
proper alignment if drive train shifts under heavy loading.
Two magnets are required for proper Hall-effect speed
sensor operation. Position them exactly opposite each other
(180 degrees apart). The polarity (north and south poles)
detected by the Hall-effect speed sensor must alternate as
the shaft is turned. The magnets provided by Micro-Trak are
marked with a punched dashed line on the SOUTH pole side
of the magnet.
• Attach magnets onto drive shaft, one NORTH pole side
out and the other SOUTH (dashed) pole side out, by
wrapping cable tie around shaft and magnets. Position
each magnet so that its longest dimension moves in
the direction of rotation. Pull cable tie tight and trim
off excess. An adjustable, non-magnetic (stainless steel)
band clamp may also be substituted.
• Attach sensor bracket to vehicle transmission. See
Illustration below. Use either the short or long end of
the bracket as a base.
• Turn one locking nut onto threaded sensor and insert
sensor into large hole selected on mounting bracket.
Turn on remaining locking nut. Set sensor to proper
distance from magnets (1/4” to 1/2”, or 6mm to 13mm).
When distance is set, tighten nuts to lock sensor in
place.
• Secure sensor cable to frame with cable ties. Place first
tie as close to sensor assembly as possible.

plug wire with electrical tape or plastic ties. The white mark
on the sensor must be positioned directly over the spark plug
wire. The spark plug wire and sensor must be as far away as
possible from all other plug wires. Route the sensor cable
away from heat and moving parts and secure them in place
with plastic ties. See Illustration 9. Connect to the RPM lead
on the main harness. See Illustration 13 on page 18.

The optional tach/shaft RPM sensor can be mounted on the
drive shaft of cars, pick-ups, 4-wheel drive tractors, planters
or to the wheel hub or fork tube on ATV’s, cycles and other
vehicles.
Rigidly fasten the sensor mounting bracket in a suitable
location, or where the drive shaft has MINIMUM up/down
movement. It may also be attached under the axle nut or fork
tube using 1/4” bolts, self-tapping screws, hose clamps or
by welding it into place. CAUTION: Disconnect the console
from the battery before welding. Secure the cable with
plastic cable ties. A rubber or plastic hose over the sensor
cable will provide added protection against debris.
1. Two magnets are required for proper Hall-effect speed
sensor operation. Position them exactly opposite each
other (180 degrees apart). The polarity (north and south
poles) detected by the Hall-effect speed sensor must
alternate as the shaft is turned. Follow these steps
the make sure you attach the magnets correctly with
alternate polarities:
2. Stick the two magnets together. Put an “x” on the top
magnet. Remove the magnet and put and “x” on the
second magnet. When you attach the magnets to the
drive shaft, make sure one “x” is facing toward and one
“x” is facing away from the drive shaft. The magnets will
be correctly attached with alternate polarities.
Optional Tach/Shaft RPM Sensor Installation
3. Attach magnets onto drive shaft by wrapping cable
tie around shaft and magnets. Position each magnet
so that its longest dimension moves in the direction
of rotation. Pull cable tie tight and trim off excess. An
adjustable, nonmagnetic (stainless steel) band clamp
may also be substituted. If you are using a hose clamp,
position the adjusting screw between the magnets. The
hose clamp must be non-magnetic stainless steel. When
using adhesive, thoroughly clean the mounting area of
dirt and oil.
4. With either method of attachment, wrap electrical tape
over the magnets for added protection against field
debris.
5. Adjust the sensor so that the un-threaded tip extends
1/4” (10mm) beyond the locking nut with a 1/4” to 1/2”
(6mm to 12mm) air gap from the tip of the sensor to the
magnet. See Illustration 10. Be sure that the cable tie or
hose clamp adjusting screw will not hit the sensor when
it is rotated. The sensor may be angled up to 45º from
perpendicular, but it must be positioned directly over
the magnets.

In addition to the standard Hall-effect magnetic speed
sensor, the FlowTrak II may be interfaced with a variety of
other speed sensing equipment. Several options are listed
below.
Astro GPS Speed Sensor
The Astro is an easy-to-install economical alternate to radar
speed sensors. The Astro is available with either a 1 HZ or 5
HZ GPS receiver. The sensor converts GPS signals to a pulsed
speed signal, providing an accurate speed input even in
conditions where radar does not perform well.
Vansco™Radar Speed Sensor
The Vansco radar speed sensor uses a microwave (radar)
signal to deliver a reliable, accurate speed signal for electronic
equipment. It features state-of-the-art electronic design/
manufacturing, rugged aluminum housing and complete
testing and certification.
Radar Interface
The SpeedOMeter may also be interfaced with most popular
radar ground speed sensors. An adapter cable is required for
proper interface.
GPS Speed Sensor Interface
The SpeedOMeter may also be used with most other GPS
speed sensors that output a pulsed signal, such as SkyTrak
or Dickey-John GPS speed sensors. An adapter cable may
be required.
Contact a Micro-Trak dealer/distributor for details on any of these products,

Field Calibration - Speed and Distance
14
The SPEEDOMETER must be properly calibrated to ensure
accurate operation. Follow these instructions for calibrating
speed and distance.
The automated calibration procedure requires that you drive
a distance that is one tenth of the target distance units. For
miles per hour, you will drive 528 feet, or one tenth of a mile.
For kilometers per hour, you will drive 100 meters, or one
tenth of a kilometer.
Select a safe and convenient area to mark the beginning and
end of a 528 foot (or100m) calibration course. Allow plenty of
room before and after the course for maneuvering.
1. If your vehicle is equipped with a wheel driven distance
sensor,youmay nowpositionthe vehicleatthe beginning
marker. For non-contact (radar or ultrasonic) sensors,
drive to a position which will allow the vehicle to reach
normal speed as it passes by the beginning marker.
2. With the console turned ON, select the SPEED CAL
position on the rotary switch. The display will show the
existing distance calibration number (factory default is
1810) and a small blinking CAL indicator.
3. Holding the CAL RESET button for three seconds will
clear (zero) the display and cause the CAL indicator to be
on solid. In this condition:
• Each distance sensor pulse will increment the display
register.
• Pressing the CAL RESET button at any time resets this
count to zero.
• The final count is stored when the rotary switch
position is changed. This distance calibration number
is the total count received from the sensor while
covering the calibration course.
4. Begin your calibration course drive. If you started before
the beginning marker, momentarily press CAL RESET
switch while passing the beginning marker.
5. As you pass the calibration course’s end marker, move
the rotary switch out of the SPEED CAL position. The
distance calibration is complete. It is recommended that
you re-select SPEED CAL and record the new distance
calibration number.
NOTE: SPEEDOMETER will not store a number less than
ten. Illustration 11
Optional Distance Calibration
If your distance calibration number is known, it may be
entered directly into the console. This feature enables
the operator to enter known calibration values, or make
corrections, without going through the field calibration
steps. Follow these instructions to do so:
1. Turn the rotary switch to the “SPEED” position. Press
and hold the “CAL/RESET” switch for three seconds. The
small CAL indicator will begin flashing. You now have
three seconds to select the “DISTANCE” position and
begin holding the “CAL/RESET” switch again. After three
seconds, the CAL indicator will be on steady, and you
may release the “CAL/RESET” switch. The readout will
now display the distance calibration number which is
one tenth the number of pulses accumulated each mile
(kilometer).
2. Moving the switch to any position other than “SPEED”
or “DISTANCE” will exit calibration. While in “SPEED”
position, pressing the “CAL/RESET” switch will decrease
the calibration number, and in the “DISTANCE” position,
pressing the “CAL/RESET” switch will increase the value.
The factory default is 1810, which is the number required
for mile calculations using Micro-Trak’s ultrasonic Trak-Star
(3.5 inches/pulse). For a wheel driven distance sensor, if the
distance (d) traveled between magnets passing under the
sensor is known, you can calculate the required distance
calibration number.
• Miles: 6336 / d (inches)
• Kilometers: 100,000 / d (millimeters)

RPM Calibration
Illustration 12
Follow these instruction for calibrating RPM:
1. Turn the rotary switch to the RPM CAL position. The
display will show either a “2C” or a “4C” along with a
small blinking CAL. See Illustration 12.
• For gas engines using inductive sensors, two cycle
engines require a “2C,” while most four cycle engines
require a “4C” (four cycle engines that spark each
revolution require “2C”).
• For magnetic sensors, shafts equipped with two magnets
require a “2C”.
2. If the proper value is displayed, the RPM readout will
be accurate. If the display is showing the incorrect
value, hold the CAL RESET button in for three seconds.
The display will change to the other value, and RPM
calibration is complete.
Operation
Measuring Speed
To measure speed, turn the dial to the “SPEED” position.
Your speed will be displayed in MPH (km/h). By monitoring
this function during such operations as spraying or fertilizer
application, you can be sure of maintaining a uniform
application rate.
Measuring Distance
To measure total distance, turn the dial to the “DISTANCE”
position. Distance will be displayed in miles or kilometers
(depending upon your calibration). This counter will add up
total distance traveled and cannot be reset.
To measure trip distance, turn the dial to the “TRIP” position.
Distance will be displayed in miles or kilometers (depending
upon your calibration). This counter will add up distance
traveled and may be reset to zero. Refer to Resetting Counters
below for details.
Measuring Hours
To measure total hours, turn the dial to the “HOURS” position.
The display will show the total hours that power has been
supplied to the console. This counter will add up total hours
when the console is turned ON and cannot be reset.
Measuring RPM
To measure RPM, turn the dial to the “RPM” position with
the optional RPM/tach sensor installed, the display will read
revolutions per minute of the monitored engine or shaft.
Resetting Counters
Reset Trip
To reset the “TRIP” counter, turn the rotary dial to the
“RESET TRIP” position. Press the “CAL/RESET” button to reset
the counter to zero.

Optional Features
Excessive Speed/Backup Alarm
The SPEEDOMETER is equipped with an excessive speed
function which alerts the operator when a predetermined
speed is exceeded (external alarm not included). A factory
activated backup indicator is also available to detect reverse
movement and activate an external alarm (alarm and wiring
not included).
The over-speed Alarm trip point can be entered directly into
the console. Turn the rotary switch to the “TRIP” position,
press the CAL/RESET button for three seconds. The small
CAL indicator will begin flashing. Within three seconds turn
the rotary switch to the HOURS position and begin holding
the CAL/RESET button again. After three seconds, the CAL
indicator will be on steadily, and you may release the CAL/
RESET button. The readout will now display the Over-speed
Alarm trip point. With the rotary switch at HOURS, the
CAL/RESET button will increase the over-speed alarm trip
point. With the rotary switch at TRIP, the CAL/RESET button
will decrease the over-speed alarm trip point. Turn to any
position other than TRIP or HOURS to exit CAL.

Troubleshooting
General
All SPEEDOMETER consoles are tested prior to packaging.
Unless there has been damage in shipment, everything
will be operational when you receive it. However, if you
do encounter a problem that appears to be related to
equipment failure, please DO NOT open the console. Your
system is protected by a warranty and Micro-Trak will gladly
correct any defect.
Many problems are the result of mistakes in installation or
operation. Before returning any parts for service, carefully
check your installation and review the operating instructions.
For easy-to-follow guidelines, refer to the troubleshooting
section which follows.
If, after performing all the tests and operations and answering
all the questions pertaining to your problem, you cannot
identify the problem, the Micro-Trak service department will
be glad to assist you.
CONSOLE OR CERTAIN FUNCTIONS APPEAR DEAD
Using your test light, check for 12 volts at the power source.
Also check for damaged power cables or reversed terminals.
(Console requires 12 volts for proper operation.)
SPEED IS ALWAYS ZERO OR ERRATIC
Make sure that at least two magnets are installed, with
alternating polarities. Review speed sensor installation. Check
for proper mounting, alignment and spacing of speed sensor
in relationship to magnet assembly. Be sure sensor extends
1/4” (7mm) or more beyond outside locking nut.
CONSOLE IS ERRATIC IN OPERATION
If you have a two-way radio, it may be mounted too close
to the console. Ignition wires may be causing console to
malfunction. Install ignition suppressor. Make sure chassis
ground is connected. Also, reroute all cables away from
electric solenoids, air conditioning clutches and similar
equipment.

Troubleshooting
Individual Component Troubleshooting
CONSOLE
The only way to field test a console is to connect it to a
harness on a vehicle with a known working console or install
it on an E-POP (Electronic Point of Purchase) display stand.
HARNESS
The harness can be check using an ohmmeter or continuity
tester. The main wiring diagram (See Illustration 13 below)
shows the pin out of all connectors. Simply check for
continuity between connected pins and for no continuity
between unconnected pins.
POWER
The main harness has a ten-pin connector labeled A-K. See
Illustration 14. Check between J and K with a volt meter or
test light. If there is no power, trace cable toward battery
looking for breaks, Also check any fuses or circuit breakers
that supply power to the console.
ACCESSORY POWER
The speed and RPM/Tach cables both have an accessory
power wire. Check for 12 volts between B (usually white) and
C (usually black) of these connectors If power is not present,
make sure the accessory power wire is not open or shorted
to ground or to another wire. If this wire has a problem, the
console may exhibit erratic behavior or not function at all.
MAGNETIC HALLEFFECT SENSOR
The Hall-effect sensor works similar to a reed switch, but
requires power in order to function. Also, this particular type
of Hall-effect sensor requires alternating magnetic polarities
in order to switch. This means that the north pole of a magnet
will “open” the Hall effect and the south pole of a magnet will
“close” the Hall effect.
Ground pin C (BLACK) and connect clean 12 bolts to pin B
(WHITE) of the Hall-effect sensor cable. Connect the positive
lead (RED) of an ohmmeter or continuity tester to pin A (RED)
and the negative lead (BLACK) of the ohmmeter or continuity
tester to pin C of the Hall-effect sensor cable. Holding the tip
of the sensor up to the north pole of a magnet should result
in a very high resistance (infinite), while holding the tip of
the sensor up to the south pole of a magnet should result in
a very low resistance (near zero).
CONSOLE INPUTS
If there is no response from any of the following tests, refer to
the main wiring diagram on the previous page to locate the
next connector in line toward the console and repeat the test
at that connector. If there is a response at that connector, the
problem may be in the cable between the two connectors (or
the connectors themselves).
SPEED INPUT
Turn rotary switch to speed position and disconnect the
speed sensor (yellow tie) from the main harness. Check for
12 volts between pins B (WHITE) and C (BLACK) of the main
harness speed cable (yellow tie). Using a clip lead or other
jumper wire (such as a paper clip bent in a “U”), rapidly short
together pins A (RED) and C (BLACK) of the 3-pin connector
several times. The console should respond with some speed
reading.
RPM/TACH INPUT
Turn rotary switch to RPM position and disconnect the RPM
sensor (no tie) from the main harness. Check for 12 volts
between pins B (WHITE) and C (BLACK) of the main harness
RPM/tach cable. Using a clip lead or other jumper wire (such
as a paper clip bent in a “U”), rapidly short together pins A
(RED) and C (BLACK) of the 3-pin connector several times.
The console should respond with some RPM reading.
