You can execute the following step by step:
[TES] [ DYN]( dynamic sensor test)
[TES] [ Dis] (test for the distance to the machine ）
[TES] [Dia] (test for the rim diameter）
[TES] [ Wid] (test for the rim breadth）
By testing the above sensors, you can quickly find the
trouble shooting point.
After entering into [SET] [UP], do not enter the [TES]-
[INT] program. Press key, you can enter the
customer weight marking(CAL WEI) You can select this
function when you consider the test result inaccurate or
the machine not used for a long time. When you enter
into this function, display will display[ ADD] –[ ]-[ 0 ]-
and press to start the machine for a time.
（This operation must be executed after mounting the
tire or rim with the relative small unbalance value and
input the correct value of the Dis, Bre and Dia）Or you
will cause the inaccurate measurement result.
When rotate the wheel to test, it will display [ADD]
[ ]–[100]. Rotate the wheel and clip a piece of
standard weight of 100Gr at the top center position
when the entire tire unbalance indicating lamp light.
And start the machine once again, you can realize the
self-calibration. This
operation can make the machine fast restore its use of
precision.
****The shortcuts is located in the operation window not
the program setup window. Press and hold on
key. Five seconds later, the program will automatically
enter the self-calibration program and the display will
display [ADD]-[ ] –[ 0 ]- The other operation steps
are similar to the above.
If need to enter the scale self-calibration, follow the
following steps：
The display will display [CAL]-[WEI]-[CAL] Press
to enter [CAL]- [RL1]-[ ]
Enter the scale calibration program：[CAL]- [RL1]-
[ ](distance to the machine) Press key to
confirm the entrance and the display will display [Dis]
-[ ]-[ 0 ]
Position the scale to the zero position, press to
confirm and the display will display [Dia]-[ ]--[14]，
Mount a medium size tire or rim on the main shaft and
then, according to the diameter of the rim and tire
mounted on the shaft, press to adjust the
14to the dimension of the rim mounted（change the
value on the right window from 14 to 16 if the diameter
of the tire mounted is 16‖）and then pull out the scale
end to lean it against the edge of the rim and at the
same time press key to confirm. Thus we have
completed the automatic dis&dia scale calibration.
Ⅱ****The shortcuts is located in the operation window
not the program setup window. Press and hold on
key. Five seconds later, the program will
automatically enter the self-calibration program and the
display will display [ADD]-[ ] –[ 0 ]-. Then press
and the display will display [CAL]—[RL1]-[ ],
The other operation steps are similar to the above.
If need to enter the width scale self-calibrition ,follow
the following steps
The display will display.[CAL]-[RL1]-[ ] Press

7.2 ERROR INDICATION:
Attention：When change the computer board, the
phase sensor or the press sensor, you must execute
the self-calibration. When change the computer board,
you should setup the parameter according to the
parameter marked in the machine or on the original
computer board. Repeat the self-calibration after the
modification.
7.3 INSTALLATION AND WIRING OF THE PRESS
SENSOR

18
Sometimes, inaccurate balance or incorrect position is caused by the breakage of the press sensor. The
changing method of the sensor is as following:
(1)Remove the upper cover and the right side panel of the balancer.
(2)Detach the nut1 and 2, elastic washer, plain washer and large flat washer.
(3)Loose the back nut3.4.5 to detach every parts.
(4)Change the new sensors and tight the dual-head screw and then tight nut 5. The installation of the
negative and positive pole of the piezoelectric ceramics disk of the sensor must follow the picture.
(5)Use the spanner to tight the nut4 and then nut 3. At this moment, you should pay attention
to the horizontal and vertical sensor screws should be vertical. And the end of the screws should
be just fallen into the 2 holes.
(6)Mount the nut1 and 2, elastic washer, plain washer and large flat washer and completely tigh them.
Usually, lock nut 1 and then nut 2. We require to flat the elastic washer and then return the nut
1/4—1/2turn. Use this way to get the normal pre-pressure of the press sensor（use torque wrench to lock
and the torque is 40NM）
(7)There are glass glue coat on the surface of the press sensor and the normal installation result
of the piezoelectric ceramics disk of the sensor is the IR should be larger than 50MΩ.
(8)Discharge the output line of the shortcuts press sensor，insert into the computer board after discharge
to avoid the breakage of the computer board.
(9)Insert the vertical（┴）& horizontal（∥）sensor plugs according to the original position.
(10)Calibrate the balancer again and install the upper cover and the side panel after check result is
normal.
