4.4 SELECTING OPERATOR PREFERENCES
4.4.1 FINE BALANCING MODE
This balancer measures with the maximum precision
available all the time, 1g / 0.05 oz, however values below
5g / 0.25 oz are shown as zero while in the normal oper-
ating mode. Values exceeding 5g / 0.25 oz are rounded
to the amount of the nearest commercial wheel weight.
Press the NORMAL/FINE button to toggle the display
resolution between 5g / 0.25 oz and 1g / 0.05 oz.
4.4.2 OUNCE/GRAMS CONVERSION
When the machine is first turned on it is preset to dis-
play the imbalance in ounces.
Press the OUNCE/GRAM button to toggle the display
between weight in ounces and grams
4.4.3 RIM DIAMETER IN MILLIMETERS
The rim diameter is normally displayed in inches, how-
ever if the value in millimeters is desired, press and hold
the
P button while rotating the shaft until “P 7” is dis-
played”.
Repeat the above operation to convert back to inches.
Example: “ dIA ICH ” = inches
“ dIA --- ” = millimeters
4.4.4 OPERATOR SELECTION
Select the desired operator designated A,B,C, D or P1
thru P4. The System III Balancer can store wheel pa-
rameters of four operators and four other stored param-
eters. The Operator button toggles between the stored
locations with each depression.
4.4.5 Optional Weight Miser
™ ™
™ ™
™
is a software program
that determines if there is the possibility to remove suffi-
cient vibration from a tire and wheel assembly by apply-
ing a lower amount of weight than the normal balance
function recommends. The amount of residual imbalance
left on the tire and wheel assembly is determined by the
residual threshold tolerance setting.
Assuming that an amount of residual imbalance accepted
currently by the automotive industry standards is 5 grams
for static imbalance and 10 grams for dynamic imbal-
ance, a new feature Optional Weight Miser
™
allows the
tire shop to achieve wheel balancing using less – smaller
– balancing weights.
