*INSTALLATION INSTRUCTIONS *
1. The KEI-325B Display box should be permanently installed in a location that is best for the
application. It is usually mounted straight out the drivers side window on a pedestal stand.
2. When the box is installed, place a vehicle in the alignment machine and install the
mechanical fixture onto the steering wheel. Ensure that the KEI-325B display box can be
easily viewed while loading an Unfixtured Clear Vision Tool onto a steering wheel.
* OPERATING INSTRUCTIONS *
NOTE: As always, these Steering Wheel Gauges are delicate, accurate, gauging tools
that need to be treated as such and therefore must be installed in a holder when
not in use. If these tools do not have a holder & are thrown down on a table
during use, the warranty will be void.
1. Apply power to the KEI-325B by turning on the power switch located on the bottom left part
of the enclosure. This power switch also doubles as a circuit breaker for the KEI-325B
Display box. Should the breaker ever trip the power switch only needs to be turned to the
off position and back on to reset the breaker.
2. After the power has been applied to the KEI-325B Display box the LCD display will have
this display.
4. If power is applied and the KEI-325B Display box has the LCD has the following display,
the calibration data is bad and the unit needs to be calibrated.
5. The KEI-325B has 3 LED’s on the front of the Display box. These are Limit indicators of the
steering wheel guage.
6. Factory setings for these limits:
LO: -10.00 Degrees
HI: +10.00 Degrees
7. The KEI-325B also has an audible sonalert that sounds if the steering wheel gauge is
below -10.00 Deg or above +10.00 Deg.

* CALIBRATION PROCEDURE *
NOTE: Place the cal stand on a surface that is very solid and stable. The angle transducer
inside the tool is very sensitive and any movement at all will cause the numbers being
displayed to fluctuate. During the calibration procedure the cal stand should not be
allowed to tip or move, on the table, because the cal stand might become unlevel and
reduce calibration accuracy. It would be advisable to attach the cal stand to the table (eg.
Destaco clamps) to reduce the possibility for errors.
A) Install the desired Clear Vision steering wheel set tool onto a calibration stand which can be
adjusted from +60 degrees to -60 degrees in 15 degree increments. The tool that is placed
into the cal stand during the cal mode will be the tool that is calibrated.
INSURE THAT THE BACK OF THE ROLLERS, ON THE TOOL, ARE PRESSING AGAINST
THE CALIBRATION STAND ROLLER SUPPORT AT ALL ANGLES. IF TOOL IS NOT
PARALLEL TO THE CALIBRATION STAND AT ALL TIMES, CALIBRATION VALUES WILL
NOT BE ACCURATE.
B) Press the CALIBRATION push button switch once and the display will read;
Press CAL switch
again to calibrate
If a calibration procedure is to be performed, press the CAL switch a second time and the
program will go into the cal procedure. If the cal procedure is not desired, a countdown
timer will countdown for 15 seconds and the program will go back to the RUN MODE.
C) If calibration is desired, press the CALIBRATION switch again and the display will read;
xxxx Tx,CAL STND
-60 deg, PRESS SW
xxxx: is the raw A to D (analog to digital) value displayed in Hexadecimal. It will change as
the tool is tilted. (0000 = most negative angle, 8000 ~ zero degrees, FFFF = most positive
angle). At -60 degrees, the hex value should be slightly greater than 0000, at 0 degrees
near 8000, and at +60 degrees slightly less than FFFF. If at -60 degrees, the hex values is
= 0000, or at +60 degrees = FFFF, check the hex value at 0 degrees. First double check
that the cal stand is level and set to zero degrees, and that the meter is displaying a value
near 8000 hex. If the value is not near 8000 Hex, adjust the transducer, inside the box on
the tool, by loosening the 2 mounting screws and tightening it back down so that it reads
as near 8000 hex as possible. If the display still reads FFFF at -60 degrees or 0000 at +60
degrees, the amplifier gain is to high and needs reducing. If this is the case, send the unit
back to Kemkraft for modification. The Hex value is displayed to observe when the number
settles out after the cal stand has been moved to a new position.
Tx: means it will display T1 if Tool 1 is in the cal stand or T2 if Tool 2 is in the cal stand.
CAL STND -60 deg, PRESS SW: means place the cal stand in the -60 degree position and
press the CALIBRATE switch when the Hex number has settled out. (It should settle out in
a second or two).
After the switch is pressed, the display will instruct you to place the cal stand to the -45 degree,
than to -30 degrees etc. until +60 degrees is completed. When the cal stand is placed in the
+60 degree position and the CALIBRATE switch is pressed, the program will go back to RUN
mode and the calibration procedure for that tool is finished. The accuracy of the calibration
can be checked in the RUN mode by placing the cal stand into various positions and observing
the display values. If only one tool is used, the calibration procedure is finished. If two tools
are being used, and the other tool needs calibration, repeat steps A through C for the second
tool.

COMPUTER INTERFACE
The Amphenol connector on the bottom of the box is the computer interface port.
ANZEN INTERFACE:
The connector is set up for three wire RS-422 interface, ground, +signal, and -signal. When a
Clear Vision Tool is used, the limit switch on the tool closes and dumps the angle of the tool
out of the serial port in Hexadecimal.
SERIAL PORT PROTOCOL: N, 8, 1, 4800 BAUD
DUMP STRING: (02)(x)(x)(x)(03)(xx) 02 (start of text)
xx (most significant byte)
xx (middle " " )
xx (least " " )
03(endoftext)
xx (check sum)
BURKE E. PORTER / FORI INTERFACE:
The connector is set up for three wire RS-232 interface; ground, transmit and receive. The
interface cable plugs into the amphenol connector and on the other end of the cable is a 9 pin
"D" connector. The "D" connector plugs into any IBM or compatible computers' serial port.
When a Clear Vision Tool is used, the limit switch on the tool closes and 1.) displays the tools'
angle (on the KEI-325B box) and 2.) dumps the angle (in ASCII) out of the serial port.
SERIAL PORT PROTOCOL: N, 8, 1, 9600 BAUD
DUMP STRING: -xx.xx - (+/- sign of the angle)
x (tens digit)
x (ones digit)
. (decimal point)
x (tenths digit)
x (hundredths digit)
MERRILL INTERFACE:
The connector is set up for three wire RS-232 interface; ground, transmit and receive.
Connections, Protocol & Dump String are the same as Burke Porter. The only difference is
that the angle is transmitted every time the KEI-325B box receives a "Control E". ("E" is for
inquire.)
