Turning on the machine
When switched on by the mains switch
(Fig. 22, item 1)
the
electronic unit performs a number of self-tests. On successful
completion of these tests a melodious three-tone signal is
given. OK is read out on the displays, and the code number of
the program version is briefly viewed on the display; then both
displays show wheel dimensions which were entered before
and are still stored in the electronic memory.
As long as the machine is carrying out the self-tests, no inputs
and no other operations whatsoever must be made. During this
starting phase the machine must not be subjected to even the
slightest vibration.
The electronic unit is factory-adjusted to the following modes of
operation, which are available after turning on:
-
car wheel with nominal dimensions in inches, width 6.5
and diameter 15.0
-
entry of rim data in inches
-
display of amount of unbalance in 1/4 ounce increments
-
suppression of minor unbalance readings (limit set to
1/4 ounce)
-
compensation of adapter unbalance switched off
-
start of measuring run by START key
