IMPORTANT SAFETY INSTRUCTIONS
READ ALL INSTRUCTIONS
1. Eye and face protection recommendations:
“Protective eye and face equipment is required to
be used where there is a reasonable probability
of injury that can be prevented by the use of
such equipment.” O.S.H.A. 1910.133(a) Protective
goggles, safety glasses, or a face shield must be
provided by the owner and worn by the operator
of the equipment. Care should be taken to see
that all eye and face safety precautions are followed by the operator. ALWAYS WEAR SAFETY
GLASSES. Everyday glasses only have impact
resistant lenses, they are not safety glasses.
2. Do not disable hood safety interlock system, or in
any way shortcut safety controls and operations.
3. Be sure that wheels are mounted properly, the
hub nut engages the arbor for not less than four
(4) turns, and the hub nut is firmly tightened
before spinning the wheel.
4. Read and understand this manual before operating. Abuse and misuse will shorten the functional
life.
5. Be sure the balancer is properly connected to the
power supply and electrically grounded.
6. Do not operate equipment with a damaged cord
or if the equipment has been dropped or damaged – until it has been examined and repaired by
a qualified serviceman.
7. Do not let cord hang over edge of table, bench, or
counter or come in contact with hot manifolds or
moving fan blades.
8. If an extension cord is necessary, a cord with a
current rating equal to or more than that of the
equipment should be used. Cords rated for less
current than the equipment may overheat. Care
should be taken to arrange the cord so that it will
not be tripped over or pulled.
10. Wear proper clothing. Safety toe, non-slip footwear and protective hair covering to contain hair
is recommended. Do not wear jewelry, loose
clothing, neckties, or gloves when operating the
balancer.
11. Keep work area clean and well lighted. Cluttered
and/or dark areas invite accidents.
12. Avoid dangerous environments. Do not use power
tools or electrical equipment in damp or wet locations, or expose them to rain.
13. Avoid unintentional starting. Be sure the balancer
is turned off and power disconnected before
servicing.
14. Disconnect the balancer before servicing.
15. Use only manufacturer’s recommended accessories. Improper accessories may result in personal
injury or property damage.
16. Repair or replace any part that is damaged or worn
and that may cause unsafe balancer operation. Do
not operate damaged equipment until it has been
examined by a qualified service technician.
17. Never overload or stand on the weight tray or any
part of the balancer.
18. Do not allow untrained persons to operate machinery.
19. To reduce the risk of fire, do not operate equipment in the vicinity of open containers or flammable liquids (gasoline).
20. Adequate ventilation should be provided when
working on or operating internal combustion
engines.
21. Keep hair, loose clothing, fingers, and all parts of
body away from moving parts.
22. Use equipment only as described in this manual.

Owner’s Responsibility
To maintain machine and user safety, the responsibility
of the owner is to read and follow these instructions:
Definitions of Hazard Levels
Identify the hazard levels used in this manual with the
following definitions and signal words:
• Follow all installation instructions.
• Make sure installation conforms to all applicable
Local, State, and Federal Codes, Rules, and Regulations; such as State and Federal OSHA Regulations
and Electrical Codes.
• Carefully check the unit for correct initial function.
• Read and follow the safety instructions. Keep them
readily available for machine operators.
• Make certain all operators are properly trained,
know how to safely and correctly operate the unit,
and are properly supervised.
• Allow unit operation only with all parts in place and
operating safely.
• Carefully inspect the unit on a regular basis and
perform all maintenance as required.
• Service and maintain the unit only with authorized
or approved replacement parts.
• Keep all instructions permanently with the unit
and all decals/labels/notices on the unit clean and
visible.
• Do not override safety features.
Operator Protective Equipment
Personal protective equipment helps make tire servicing safer. However, equipment does not take the
place of safe operating practices. Always wear durable
work clothing during tire service activity. Loose fitting
clothing should be avoided. Tight fitting leather gloves
are recommended to protect operator’s hands when
handling worn tires and wheels. Sturdy leather work
shoes with steel toes and oil resistant soles should be
used by tire service personnel to help prevent injury
in typical shop activities. Eye protection is essential
during tire service activity. Safety glasses with side
shields, goggles, or face shields are acceptable. Back
belts provide support during lifting activities and are also
helpful in providing operator protection. Consideration
should also be given to the use of hearing protection if
tire service activity is performed in an enclosed area, or
if noise levels are high.

Set Up Instructions
Receiving
The shipment should be thoroughly inspected as soon
as it is received. The signed bill of lading is acknowledgement, for the carrier, of receipt in good condition
of the shipment covered by our invoice.
If any of the goods called for on this bill of lading are
shorted or damaged, do not accept them until the carrier makes a notation of the shorted or damaged goods
on the freight bill. Do this for your own protection.
NOTIFY THE CARRIER AT ONCE if any hidden loss or
damage is discovered after receipt and request him to
make an inspection. If the carrier will not do so, prepare
an affidavit to the effect that you have so notified the
carrier (on a certain date) and that he has failed to
comply with your request.
IT IS DIFFICULT TO COLLECT FOR LOSS OR DAMAGE AFTER YOU HAVE GIVEN THE CARRIER A CLEAR
RECEIPT.
File your claim with the carrier promptly. Support
your claim with copies of the bill of lading, freight bill,
invoice, and photographs, if possible.
Although COATS responsibility ceases upon delivery
of the shipment to the carrier, we will gladly assist
in tracing lost shipments. Our willingness to assist in
every possible manner does not make COATS responsible for collection of claims, or replacement of lost or
damaged materials.
Electrical Requirements
See serial tag for the appropriate power requirements
of your machine.
Always have a qualified electrician install the proper
receptacles in accordance with state and local codes.
Machine Set Up
CAUTION
Do not use the control panel, control panel
base, accessory storage, faceplate, hood or
shaft to lift the balancer.
CAUTION
Do not attempt to install and set up the unit
yourself. Contact COATS as noted below.
A factory trained COATS Service Technician must
perform the install, set up, and initial test procedures on
your wheel balancer. Do not attempt to install and set
up the unit yourself. Accurate and reliable operation of
your unit depends on proper installation. Please contact
COATS directly at 86-512-62620469 for the Certified

Floor and Space Requirements
The balancer must be located on a flat floor of solid
construction, preferably concrete. The balancer must
sit solidly on its three feet. If the balancer is not level,
does not sit solidly on its three feet, or is placed on an
unstable floor, the balancer will not function properly
and may produce inaccurate balance readings.
Do not operate the balancer while it is on the pallet.
Select a location for the balancer that provides a level,
solid floor, and adequate clearance around and above
the balancer. Make sure the location selected has
enough room above and behind the unit so the hood
can be raised completely. The location must also provide working room for mounting and removing wheels.
Make sure the area has adequate lighting.

Mounting Wheel On Balancer
Shaft
CAUTION
Avoid back injury, seek assistance when
lifting heavy tire/rim assemblies onto the
balancer shaft.
CAUTION
Failure to tighten the hub nut properly may
result in the wheel dismounting, causing
personal injury and property damage.
Select the most appropriate mounting method for
the wheel you are balancing. Using the proper method
ensures secure mounting and safe balancer operation,
and prevents damage to the wheel.
On most wheels, the inner side of the wheel hub usually has the most uniform surface for wheel balancing.
Always center the wheel by the most uniform shaped
side of the hub to achieve the most accurate balance.
Regardless of mounting type, on standard units,
always make sure that the wheel is forced firmly against
the shaft faceplate and that the hub nut engages the
threaded shaft for at least four complete turns. To assist
in centering the wheel properly, rotate the wheel and
the shaft while tightening the hub nut.
Standard Back Cone Mounting
Most original equipment and steel wheels can be
mounted properly using this method. The wheel is
centered on a cone from the inner side of the hub.
Faceplate
Cone
Spring
Figure 13 - Standard Back Cone Mounting
1. Place the cone spring onto the balancer shaft with
the large end towards the faceplate.
2. Select the cone that best fits the center hole in the
wheel. Slide the cone onto the shaft with the large end
towards the cone spring.
3. Lift wheel onto the shaft and center it on the cone.
4. Attach pressure cup to hub nut. Install the hub nut
assembly onto the shaft and tighten it securely against
the wheel. The wheel must be forced firmly against the
faceplate. The hub nut must engage the threads for at
least four full turns
Note: Use a nylon spacer (protective ring) to protect
custom wheel finishes.

Standard Front Cone Mounting
A wheel should be centered by the outer side of the
hub only when the inner surface will not provide an
accurate surface to center on.
Alternate Mounting
If the wheel has a protruding outer hub which will not
permit the use of the pressure cup, or the cup will not
permit the hub nut to engage at least four turns of the
shaft, this alternate method should be used.

Direct Select™ Weight Location
Setting Wheel Dimensions (DIM)
Before spinning the wheel, use direct select to indicate
weight placement locations on the wheel as follows:
Figure 16 - Direct Select™ Weight Keys & Wheel Crosssection Diagram
Note: When the machine is turned ON, the balancer
defaults to a 2-plane dynamic mode using standard
clip-on wheel weight locations (Clip 1 and Clip 2) and
wheel dimensions.
Clip 1 (default) - select this location to place a stan-
dard clip weight on the Inboard rim flange.
Before a wheel can be balanced, wheel dimensions
must be entered into the computer.
Definition of Dimensions (DIM)
A = Offset
The distance measured from the balancer (“0” on offset arm) to inner plane of the rim (inner weight location).
W = Width
The width of the wheel at the rim flanges, measured
with the calipers as shown in figure 19.
Note: Only use calipers provided by the wheel bal-
ancer manufacturer because others may not be the
same.
D = Diameter
The diameter of the wheel as indicated on the tire.
Note: A thick flange, on some aluminum wheels, can
effect the measured diameter. For example, a 16-inch
rim can have a measured diameter of 15.5-inches.
T1 Tape - select this location to place an adhesive
weight on the Inboard side of the wheel that is the
horizontal plane at the outer edge.
T2 Tape - select this location to place an adhesive (hid-
den) weight on the Outboard side of the wheel that is
the horizontal plane in the inner area.
T3 Tape - select this location to place an adhesive
weight on the Outboard side of the wheel that is the
horizontal plane at the outer edge.
Clip 2 (default) - select this location to place a stan-
dard clip weight on the Outboard rim flange.

Balancing A Wheel
A variety of wheel configurations can be balanced
using this wheel balancer. Read through this section,
it will help in determining which balancing mode and
options are best suited for certain wheel assemblies.
Remember: As with any balancing procedure, first
remove any weights attached to the wheel, inspect the
tire and wheel, and use the most appropriate balancer
mounting method before beginning.
Dynamic Balancing
Choose a dynamic balance to balance a wheel using
two planes for correction. Select the weight option that
best fits the available weight locations on the rim.
Clip-on Weights - The standard default; used for most
passenger tire/wheel assemblies using the most common location for corrective weights. Clip-on weights
are placed on the inner (inboard) and outer (outboard)
rim flanges.
ALUS (Aluminum Wheels) - To balance aluminium
wheels you usually use a self-adhesive weight location
that is positioned differently from the clip-on weight
position(s) used in standard balancing. Be sure to use
the appropriate wheel data entry method since the
balancer calculates out of balance values based on the
wheel dimension measurements (DIM) entered for the
tire/wheel assembly.
Static Balancing
Choose a static balance to balance a wheel using one
plane for correction. Place the single corrective weight
at top-dead-center (12 o’clock) on either flange, at the
center of the rim channel, placed inward either side, or
split on either sides.
Figure 21 - Static Balance Weight Locations
Note: When in static mode, you only need to input the
DIAMETER wheel measurement.
Important: If you decide to use the rim channel for
corrective weight placement, remember you may need
to adjust the DIAMETER measurement input. Typically
you would make it 2 or 3 inches less than the actual tire/
wheel diameter.
Figure 20 - Dynamic Balance Weight Locations
Note: When the machine is switched on, a standard
dynamic balance using clip-on weight locations is the
default setting.
14 • Important: Always read and follow instructions.
Page 19
Behind Spoke Mode (1150-2D only)
“Splitting” the T2 Tape corrective weight amount is
used to hide the adhesive weight behind two rim
spokes.
1. When the unbalance is displayed, rotate wheel
until Inboard center bar blinks. Attach Inboard corrective
weight at top-dead-center.
2. Next, rotate wheel until the outboard center bar
blinks.
3. Select the Behind Spoke mode option. “SP1” will
display in the static display window.
4. Rotate the wheel toward front until the first spoke
is at top-dead-center.; press Spoke and 1 illuminates.
“SP2” will display in the static display window.
5. Rotate the wheel toward rear until the second
spoke is at top-dead-center; press Spoke and 2 illuminates. Now at the Spoke 2 location, the Outboard
center bar stops blinking.
Corrective Weight Placement
After the wheel spins and out of balances are measured and displayed, the corrective weight amount
appears on the weight display window for Inboard and
Outboard weight locations. Bars appear on either side
of the wheel cross-section diagram to aid in positioning
the wheel for corrective weight at the application point.
After a measurement cycle, rotate wheel until the
center weight position bar blinks, indicating the correct weight placement position is at top-dead-center.
If the out-of-balance is less than the chosen threshold
value, 000 appears instead of an out-of-balance value
to indicate that, on that particular side, the wheel is in
tolerance.
Figure 22 - Spoke 1 and Spoke 2 Locations On Either Side Of
Original Outboard Weight Location
6. Attach the Spoke 2 Outboard corrective weight at
top-dead-center behind spoke 2.
7. Next, rotate the wheel toward the Spoke 1 location
until the outboard center bar is blinking.
8. Attach the Spoke 1 Outboard corrective weight at
top-dead-center behind spoke 1.
9. Respin tire/wheel to check balance.
Important: Always read and follow instructions. • 15

Match Balance (Optimization)
Match Balance involves the loosening of
tire beads and the inflation of a tire. Training
is necessary in tire changer operation and
understanding the dangers involved during bead seating and tire inflation before
attempting this stage of the Match Balance
procedure. Read the operators manual supplied with the tire changer and consult a
supervisor.
Use the Match Balance (Tire/Rim Weight Optimization)
program to determine the best mating of tire and rim
that will result in the least amount of total unbalance of
the assembly. It requires two spins and two rotations
of the tire on the rim. Match Balance may be needed
when:
• The customer complains of ride problems.
• The balancer calculates a high out of balance.
• The balancer calls for Total Static weights in excess
of 3 ounces (85 grams) on passenger car tires.
Match Balance Mode
If you choose to use Match Balance to correct for a
condition, such as a large static unbalance, then follow
the machine prompts and instructions for the MATCH
BALANCE procedure as outlined in the following steps.
Note: Use this procedure only after the wheel has
spun and the corrective weight amount is displayed.
Note: Use the Total Static display option. See Balance
Options, page 14, for further details.
1. Press Match to select the Match Balance mode. A
“1” will appear in the Outboard weight display.
2. Raise the hood and rotate the wheel until the valve
stem is at top-dead-center. Mark the tire sidewall at the
valve stem.
3. Press Function on the control panel; a “2” will
appear in the Outboard weight display.
4. Remove the wheel assembly from the balancer.
5. Using a tire changer, rotate the tire 180 degrees
on the rim.
6. Remount wheel assembly on the balancer. Press
Function on the control panel; a “3” will appear in the
Outboard weight display.
Important: A high unbalance may indicate the
improper mounting of the assembly on the balancer, or
a rim that is out of round or misformed, or a tire with a
bubble or other problem. If the unbalance is excessive,
it may be prudent to replace the rim, the tire, or both. If
either is replaced, do not continue with Match Balance.
Balance the new tire and rim and evaluate the readings.
7. Lower the hood. The wheel spins; a “4” will appear
in the Outboard weight display.
8. When the wheel stops spinning, raise the hood
and rotate the wheel until the valve stem is at top-deadcenter.
9. Press Function on the control panel. Weight
amounts appear on the control panel.
The amount in the Inboard weight display is the weight
imbalance for the rim. The amount in the Outboard
weight display is the weight imbalance for the tire. Use
these weight amounts to determine the suitability of
the rim or tire.
Note: If either the rim or the tire weight amount is
close to zero or zero then using Match Balance will not
affect the total unbalance of the assembly.
10. Rotate the wheel until the Outboard weight posi-
tion bar flashes. Mark the tire at top-dead-center.
11. Remove wheel assembly from balancer.
12. Using a tire changer, rotate the tire until the mark
is aligned with the valve stem.
13. Remount the wheel assembly on the balancer.
14. Press Function to exit Match Balance. Select a
balancing mode and balance the wheel assembly.
16 • Important: Always read and follow instructions.

Calibration Program
Important: Be sure to use the correct calibration
weight amount: a 4-ounce calibration weight with the
ounce option or a 100-gram calibration weight with the
gram option activated. Be sure to deactivate the Round
Off option.
Machine Calibration
For machine calibration, proceed as follows:
1. Mount a 14, 15, or 16-inch steel tire/wheel assem-
bly on the balancer. A balanced tire/wheel is required.
Note: Position wheel so that no weights are on either
flange at the top-dead-center location. Turn the machine
OFF then ON.
2. Press and hold Calibration key for three (3) seconds
to select Machine Calibration mode.
3. Press “D” key to enter the D (diameter) dimension.
Press the Up and/or Down arrow key to adjust numbers.
A valid data entry is either “14”, “15”, or “16”.
4. Press the Function key.
5. Lower the hood and press the START key to begin
the measurement cycle.
6. After the tire/wheel stops spinning, raise the hood.
Important: It is critical that the inner weight be placed
accurately to achieve proper calibration. If the calibration
weight is not moved from the outside flange directly
across to the inside flange, an inner weight placement
error will occur and the calibration will be “failed”.
Figure 25 - Calibration Weight On Inboard Flange At Top-DeadCenter
11. Lower the hood and press the START key to
begin the measurement cycle.
12. After the tire/wheel stops spinning, machine dis-
plays “100, END CAL”.. Machine Calibration is complete.
13. Press FUNCTION to exit.
7. Rotate wheel until the Outboard center bar blinks.
Attach calibration weight (either 4-ounce or 100 gram) to
the outboard flange at top-dead-center.

inside flange at top-dead-center.
Important: Always read and follow instructions. • 17
Page 22
Arm Calibration
Important: Always perform the Arm Calibration imme-
diately after Machine Calibration. The balancer software
will not permit it otherwise. During Machine Calibration,
the balancer software calculates both the A (offset) and
W (width) dimensions. The Arm Calibration gives the
balancer software a reference point to the edge of the
faceplate and home position. When the user enters the
A dimension from the arm rod, it calculates the difference from the Machine Calibration A and uses that as a
factor for the manual A entry. Arm Calibration also gives
the D dimension a reference point from home position.
1. Complete the Machine Calibration procedure (see
page 17).
2. Press and hold the Function key and Calibration
key for three (3) seconds to select the Arm Calibration
mode.
3. Bring the tip edge of the arm precisely to the outer
edge of the faceplate and hold it there while pressing
the Function key. If necessary to reach the faceplate
accurately, loosen the calibration wheel temporarily.
4. With the arm still at the edge of the faceplate,
press A key and use UP / DOWN arrow to adjust A
dimension value as shown on arm gauge. Display will
show at static position of LED. Press Function key.
8. Return arm to home position.
9. When machine displays “END”, the Arm Calibration
is complete. Press FUNCTION to exit.
Important: To redo the Arm Calibration procedure,
press and hold FUNCTION and press “Clip 1” for 3
seconds to enter CDE mode, then press “T1 Tape” then
press “W” to bypass the Machine Calibration requirement. Always use the same wheel assembly that was
used during the Machine Calibration or else the calibration will not be correct.

Maintenance Instructions
Use common sense, this is an electrical
device. Exposing the balancer to water,
either by hose or bucket, or by exposure
to rain or snow, may cause risk of shock
or electrocution to operator or bystanders.
Place, store, and operate the balancer only
in a dry, sheltered location.
CAUTION
Do not hose down with water or bucket
wash the balancer. Extensive damage to
the balancer will result. Sensitive electronic
components, wiring harnesses, and other
devices housed in the balancer are not
intended to be exposed to water.
The balancer requires only minor maintenance to keep
the unit operating properly.
1. Keep the display clean and clear. Use a damp cloth.
Do not use cleaners or solvents which leave oily or filmy
residues behind.
2. Keep the adapters, cones, faceplate, threaded
shaft, pressure cup, and hub nut clean. Grease and dirt
buildup will cause inaccurate balancing and premature
wear. Clean these items at least once a day with a
vaporizing solvent.
3. Clean weight tray and any accessory posts, pegs,
or storage shelves with a vaporizing solvent. Weights
stored in a dirty tray may pick up grease and dirt which
may keep them from securely attaching to the wheel.
4. Keep the area around and under the balancer
clear. Remove any tools or other items that are leaning
against the balancer. Remove any items that may cause
the balancer to not sit level. Be particularly cautious of
new or used wheel weights on the floor, as they may
cause personal injury due to falls.
5. Use only COATS® accessories. Accessories from
other manufacturers may not fit or function properly,
and may damage the balancer.
Important: Always be sure to remove the wheel
assembly from the pneumatic shaft before disconnecting the air supply from the machine.
Important: Always read and follow instructions. • 19

Diagnostic Procedures
After Balance Vibration Problems
If vibration is still present after balancing the wheels
and driving the vehicle on smooth pavement, remove
the wheels and recheck the balance. If a wheel is out
of balance the cause maybe:
• Wheel was not mounted/centered correctly on the
balancer.
• A weight has come off the wheel (possibly the
wrong clip style). Remove the other weights from
the wheel and rebalance.
• Foreign material inside the tire. Remove the tire
from the wheel, remove the foreign material, and
remount. Remove wheel weights and rebalance the
wheel.
Troubleshooting
A COATS® Service Technician may ask for information to help diagnose service concerns (please contact
COATS directly at 1-800-688-9240 for the Certified
Service Partner nearest you). Conveying this information to your service technician prior to servicing can help
to expedite service to your equipment. Although much
of the diagnostic information aids your COATS Service
Technician, several remedies for balancer misfunctions
are available to the operator.
Error Messages - One of the following error messages, shown in the display windows, may appear
indicating a problem with the balancer.
Note: Always exit the error message by pressing the
Up arrow+Function key; then repeat the procedure to
see if the error is eliminated.
• Stones or other foreign objects caught in the tire
tread or rim. Remove the objects. Check and rebalance if needed.
If the balancer still indicates the wheels are balanced
to within 0.05 ounces (1.42 grams) on both Inboard and
Outboard displays, the problem is not in the balance of
the wheels. Check the following possible sources of
vibration:
• Tire pressure. Bring all tires up to the recommended
PSI.
• Radial or lateral runout in the tire or wheel. Replace
the damaged part.
• Unbalance in wheel covers or trim rings. Remove
the wheel covers or trim rings and test drive. If
the vibration is gone, remove the shaft and use
an appropriate adapter to mount the wheel to the
balancer. Balance the wheel with the wheel cover
or trim ring attached to the wheel.
• Incorrectly mounted tire and wheel. Remount correctly.
• Damaged wheel bolt holes. Replace wheel.
• Worn universal joints. Replace as required.
• Drive shaft unbalance or damaged. Balance, repair,
or replace.
• Unbalance in brake rotor(s) or drum(s).
• Suspension out of alignment. Align the vehicle and
replace any damaged or worn parts.

Glossary
ALUS -Alloy wheel mode that typically requires the
use of one or two adhesive weights for correction.
Balancer Flange – Disk that mates with the disk of
the wheel mounted to the balancer. The flange also
serves to keep the wheel perfectly perpendicular to its
axis of rotation.
Balancing Cycle – Sequence of operations performed
by the user and the machine, beginning from the start
of the wheel spin to the time that the wheel is braked to
a standstill after the out of balance signals are acquired
and the relative values calculated.
Centering – Procedure for positioning the wheel on
the spindle shaft with the aim of ensuring that the
rotational axis of the wheel is aligned with the center
of the shaft.
Centering Flange (accessory) – Device serving to
support and center the wheel. Also keeps the wheel
perfectly perpendicular to its axis of rotation. The centering flange is mounted to the balancer shaft by means
of its center hole.
Cone – Conical components with center hole. When
inserted on the spin shaft, serves to center wheels with
centre holes whose diameter is between maximum and
minimum values.
Spin – Procedure starting from the action that causes
the wheel to rotate and the successive free rotation of
the wheel.
Quick Nut – Device for clamping the wheel to the bal-
ancer. The hubnut features elements for engaging to the
threaded hub and lateral pins that are used to tighten it.
Static Balancing – In static balancing only the static
component of out of balance is corrected. This is
achieved by fitting a single weight, usually at the
center of the rim channel. The accuracy of this system
increases as the width of the wheel decreases.
Threaded Hub – Threaded part of the shaft that is
engaged with the hubnut to clamp the wheel. This
component is supplied disassembled from the machine.
Out of balance – Non-uniform distribution of the
wheel mass that results in the generation of centrifugal
force during rotation.
Dynamic Balancing – Operation in which out of bal-
ance is corrected by the application of two weights, one
on each side of the wheel.
Self-calibration – A procedure whereby suitable cor-
rection coefficients are calculated by starting from
known operating conditions. Self-calibration improves
the measurement precision of the machine by correcting, within limits, calculation errors that may arise due
to alteration of the machine’s characteristic over the
course of time.
