9.7. New measurement
If after a recheck we find that the wheel has been balanced with sufficient accuracy on one of
the displays e.g. number 6 is displayed instead zero. ( at 5g cut- off threshold) then before
commencing a new measurement ( for another wheel ) the values of previous unbalance must
be erased from the machine memory. Otherwise the balancing machine will treat the new
measurement as a subsequent recheck of the wheel previously balanced. To erase, use push-
button
. After depressing the push - button the balancing machine will announce [ NEW
MEASUREMENT].

9.8. Concealed weight programme
„Concealed weight” programmeis used in balancing spoke wheels when on the outboard
correction plane the point of unbalance is sittuated in the space between spokes and it is
desired that the weight is invisible from outside the wheel. By means of this programme, the
unbalance value shown on display “3” (Fig.24)
may be split between two balancing weights to be stuck at the back of two spokes, situated
at the least distance from the point of unbalance.
Procedure for „Concealed Weight” programme:
1. Select version 6 or 7 of the balancing programme (as per item 8.3.4)
2.Enter measurement settings [ WIDTH, DIAMETER, DISTANCE] for a particu;ar wheel type
and start with key the measurement cycle of the balancing machine.
3. After the wheel is stopped correct the unbalance in the inboard correction plane, indica-
ted on display „1” in the usual way, as described in items 9.4 i 9.5 .
4. Unbalance in the outboard correction plane shown on display „3” is to be corrected with
two weights according to the following procedure :
