1. Repeat the operation 5.1.1, 100g lead block is not beneath the main shaft, the value
displayed has error.
2. Remove 100g lead block, balance the wheel (see chapter 4.5), until a zero (0) appears
in the inner and outer LEDs window.
3. Repeat the operation 5.1.1 again, if displaying “00”--“100” (±4g) and outer indicator
LEDs blink, 100g balancing weight should be beneath the main shaft (allow having ±4° error),
which indicators that self-calibration succeeds.
5.1.3 Self-calibration trouble shooting
Troubles Reasons Solutions
Display Err, -8-
1. Do not place 100g
lead block.
2. Lead wire of pressure
sensor breaks.
3. Mainboard goes
wrong.
1. Place 100g lead
block.
2. Check and connect.
3. Replace mainboard.
Error is much greater
after self-calibrating.
1. May be error of tire
itself is much greater.
2. Three memory
parameters confuse.
1. Replace a balanced
standard tire.
2. Adjust three memory
parameters and
self-calibrate.
The value 100g that is
displayed is inaccurate,
the position of lead block
is not beneath the main
shaft, and the tire can be
balanced with many lead
blocks.
1. The tire is not
standard or there are
sundries in the tire
2. Memory values dis
and SFA do not adjust
well.
3. The value that is
display is inaccurate.
1. Replace a standard
tire.
2.1 If the displayed
value is high, reduce the
value dis.
2.2 If the displayed
value is low, increase
the value dis.
2.3 When lead block is
away from the operator,
increase the value SFA.
2.4 When lead block is
back from the operator,
reduce the value SFA.
3. Shoot according to
trouble shooting.
If do not resolve by the above methods, please contact the manufacturer.
Caution:
After replacing mainboard, power panel, phase position and pressure position,
self-calibration must be carried out over again. When replace mainboard, setup its
parameters according to original parameters, the method sees 5.2. And
self-calibrate over again after modifying.
5.2 Correcting memory data
Because incorrect operations and other reasons result in losing memory parameters, adjust
as follows and make the computer return normal work. Correct parameter setup can
guarantee its balancing precision.
Trouble:
After self-calibrating, the phase position is inaccurate or the error is too greater.
