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.
