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 be-
low 5g / 0.25 oz are shown as zero while in the normal
operating mode. Values exceeding 5g / 0.25 oz are
rounded to the amount of the nearest commercial wheel
weight.
Press the Fine Mode button (number 5 on page 9) to
toggle the display resolution between 5g / 0.25 oz and
1g / 0.05 oz.
4.4.2 OUNCE/GRAMS CONVERSION
Press the OZ/Gr button on the touch panel to toggle
between ounces and grams for weight amount display.
Pressing again will revert to the previous mode.
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 the F
button followed by the UP or Down arrow button until
“F 7” is displayed”. Press “ENTER”.
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.

Weight Miser
™™
™™
™ is a software program
that determines if there is the possibility to re-
move sufficient vibration from a tire and wheel
assembly by applying 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 imbalance, a new fea-
ture Weight Miser™ allows the tire shop to
achieve wheel balancing using less – smaller –
balancing weights.
