System setup configuration
1. Place the four pads near their appropriate car tire: LF by left front, RF by right front
and so on.
2. Connect one end of each cable to a pad: LF-Red cable, RF-Green cable, LR-White
cable, RR-Black cable.
3. Connect the free end of each cable to the control box: LF-Red cable, RF-Green
cable, LR-White cable, RR-Black cable.
4. Turn the control box on.
5. Jack the car onto each pad.

Quick Start
Setup the scales as described in SETUP on previous page. Turn the scales 'on'; after
a copyright screen you will see a display screen with five weights and a percentage.
The four weights that are on the left are the individual wheel weights. The weight in the
upper right is the total selected weight. The percentage is the percentage of selected
weight to total weight. You can switch to display the percentage of each pad by
pressing SHOW AS % and go back to the weights by pressing SHOW AS WGT. The
weights and percentages are displayed in the same pattern as a car left front, right
front, left rear, right rear. You can select or deselect a pad by pressing the LF, RF, LR,
RR (left front, right front, left rear, right rear); each time you press the button a select
arrow will turn on and off to the right of that pads weight. The T (or total) display line
shows the total weight on all four pads, and the percentage shown is the percentage of
selected weight to the total weight.
Optional External Printer
Press the on/off rocker switch to the right to turn the printer 'on', and to the left to turn it
off.
If the on/off switch is held down to the right when the printer is turned on the printer will
do a self print test. After the printer is 'on' holding the switch to the right will feed the
paper through the printer.
To load paper in the printer, insert the paper into the metal slot at the back of the
printer as far as it will go, then hold the on/off switch to the right to feed the paper.

Operations
Overview
The SW scale system is designed to independently measure the force applied by each
tire of a car. This is referred to as the ACTUAL weight applied by each tire. The user
can enter the weight they want applied by each tire, this is know as the TARGET
weight. The TUNE weight is the amount of weight that needs to be added to a tire to
reach the TARGET weight. If a TUNE weight is negative it implies that the tires weight
is greater than the TARGET weight.
The SW scale can also perform a number of calculations automatically. Rather than
displaying the wheel weights (Actual, Target, Tune) the user can select to display the
weights as a percentage of the total weight, or as a percentage and weight.
Additionally the user can select pads in groups (such as left front and left rear, or left
rear and right front) and the scale will calculate what percentage of the total weight that
group is.
The scale has five additional special display modes:
TGT, TUN: In this mode the target and tune weight of all four wheels
are displayed.
SIDES: The side totals are displayed.
BITE: The front and rear bites (LF-RF and LR-RR) are displayed.
CENTER OF GRAVITY: With entry of the cars axle width and wheel base the scale
will calculate the location of the center of gravity front to
back and side to side.
VERTICAL CENTER
OF GRAVITY:
With entry of the cars wheel base and by lifting the back of
the car, the scale will calculate the vertical center of
gravity.

Zeroing pads
To set the current weight on a pad to zero press the ZERO button. The scale will then
ask you to press LF, RF, LR, RR, or ZERO. Pressing ZERO again will zero all of the
weigh pads; the other key presses will zero only that weigh pad (i.e. LF: left front pad
only, and so on).
When the scale is turned 'off' the current zero will be remembered. That means that if
a car is on the weigh pads and the unit is turned 'off'; when the scale is turned 'on' the
current weight will be displayed, not zero.

Selecting pads
On various display screens a S, T, and % line are shown; they have the following
means:
S: Total selected weight (total of pads turned on).
T: Total weight (total of all four pads).
%: The percentage the total selected weight is to the total weight.
To change which pads are selected use the LF, RF, LR, RR, ALL, left arrow, right
arrow, up arrow, down arrow. The arrow to the right of each pads weight display is
turned on if the pad is selected and off if it is not.
LF: Toggles left front pad on and off.
RF: Toggles right front pad on and off.
LR: Toggles left rear pad on and off.
RR: Toggles right rear pad on and off.
ALL: Turns all four pads on.
Left arrow: Turns LF and LR on, RF and RR off; for left side.
Right arrow: Turns LF and LR off, RF and RR on; for right side.
Up arrow: Turns LF and RF on, LR and RR off; for front side.
Left arrow: Turns LF and RF off, LR and RR on; for rear side.
Display format
The SW Scale has nine basic display screens. The Actual (weight on pad), Target
(weight you want on the pad), and Tune (the difference); can be displayed as either
weight, percentage, or weight and percentage. This gives a total of nine screens (see
appendix B for display screen examples).
The SHOW AS (WGT, %, or WGT & %) keys pick how the information will be
displayed. The SHOW (TARGET, TUNE, or ACTUAL) keys pick what information will
be displayed.
Period
Pressing the period (.) key will display information about the current display,
press period to return to the normal screen. The information displayed is: what
is currently being viewed, the current unit of measure, and the current register
number; see Appendix B.
