F.2 Self correction
Self correction has been finished in the factory. If you use for many years and change part or doubt balance to be a big
error, you can self correct it again.( Choose one medium-sized tyre to install on main shaft, uneventy of steel rim on both
sides of wheel is relatively slight, only 13 inches and 14 inches). Input correct number of this tyre A, L , D.
Attention: incorrect input of size will lead to that machine can’t correctly
determine caliber so following measurement will have errors.
●
Press R key, at the same time press START key in half a second ,display board
shows “CAL”-“CAL”, indicator lamps are all on. After indicator lamp goes out, then
loosen one’s grip.
●
Press START key, the wheel rotated and brakes automatically, the display board
shows ND-CAL, show self correction is over.
●
Press START key, the wheel rotated and brakes automatically, the display board
shows ND-CAL, showself correction is over.
●
Press START key, stop in 8 seconds ,show the data, this step is to see directly if self
correction is successful and accurate.
●
Well–balanced tyre by this achine shows data is “00”-
“100” (±4g )after
self correction.
100g lead lump is rightly under main shaft when outside indicator lamps are all on
( 4°error is allowed), this proves phase angle is correct.
Lights are all on when 100g lead lump is rightly under main shaft.
Two key elements to judge if self correction is accurate
1. Accurate number indication
2. Show that phase is right
(namely outside indicator lamps are all on and 100g lead lump is rightly under shaft).
Problems that occur after self correction:
●
Number indicated is ok, but phase is inaccurate, deviation is very great.
Trouble: do not reduce after finishing striking the lead lump, usually the store device is damaged. Change it.
●
Showing ERR (this machine screen shows Err. -8-)
A .Problems with computer board.
B .The circuit of sensor is broken.
●
Number indicated has a big deviation, namely within 10g. (not affect using )
