3OPERATION
3.1 Set-Up on Vehicle
The vehicle must be stationary (at a complete stop) prior to commencement of the test.
Mount the Suspension Meter to the body of the vehicle, placing it near the wheel that is to be
tested. The device uses rubber suction cups that grip onto the body of the vehicle. Please
note that dirt particles on suction cups might damage body paint as well as can result in
loose grip, which can result in device falling down on ground.
The AUTOSTOP™ Suspension Meter is self-aligning by identifying its orientation at the
beginning of each test. The suspension meter can be installed at any angle facing any
orientation, but must be well secured for the entire duration of the test as movement can
cause erroneous readings. Before commencing the test, give the vehicle a firm shake to bring
shock absorbers at their natural position.
3.2 Running the Test
Turn on AUTOSTOP™ Suspension Meter by pressing the ON/OFF button if the device is
currently off. The Suspension Meter will go through a start-up procedure and will eventually
display Main Menu (a menu of three icons):
Before starting a test, make sure the device has sufficient (over 30%) battery life. To run a
suspension test, select “RUN TEST” by pressing ‘1’ from the keypad. The device will show
the following list of options on the screen:
1. Run New Test
2. Show Last Test
3. Print Last Test
4. Delete all Tests

6. Return to Main Menu
Now select 1. Run New Test by pressing 1once again. The device will ask the user to
confirm if the shock absorbers are warmed up or if the vehicle has been in motion for at
least 5 minutes during the last 30 minutes. Running a suspension test on a cold vehicle may
lead to erroneous result.
Has the vehicle been in
motion for at least 5 min
within the last 30 min?
1. Yes
2. No

AUTOSTOP™Suspension Meter - User Manual v3.01 Page 4
After the warm up confirmation, the device will prompt for Test Mode.
Select Test Mode?
1. By Driving
If you are selecting option 1. By Driving, please make sure you drive the vehicle forward
and suddenly apply foot bake for testing the front two wheels. For testing the rear two
wheels, please make sure you reverse the vehicle and suddenly apply hand brake. Please be
mindful of other people around while driving the vehicle.
After selecting the Test Mode, the device will prompt for Examiner ID (Operator Name).
Use the device’s keypad to type in the name of the person performing the test. The DEL key
behaves like the Backspace key in a PC keyboard and it can be used to erase the last
character in the input field.

3. Hard (Sporty)
4. Manuf. Defined
5. Unknown
If the vehicle being inspected has a chassis system that was designed to be soft or
comfortable, select option 1. For normal vehicles such as an average European vehicle, use
option 2. If the chassis system is designed be hard or has characteristics of a sports car, use
option 3. If the reference damping factor for a particular vehicle is known, user can select
option 4(Manufacturer Defined) to specify reference damping data for that vehicle (see
Section 3.6). If the user is unsure about the chassis type, select option 5. By selecting option
‘5. Unknown’, reference method will not be used.
The device will now prompt for wheel selection. Select the wheel that you are currently
testing by pressing numbers from 1to 4using the keypad. Press 5to cancel the test and
return to the RUN TEST menu.
If the vehicle registration number you just typed in has any wheel that was recently tested,
the device will not show those wheels that are already tested, instead it will only show
wheels that are yet to be tested. If you want to overwrite a test for a particular wheel that is
already tested, then select 6. List all wheels* and then select the wheel that you want to test
again.
1. Front Left
2. Front Right
3. Rear Right
4. Rear Left
5. Cancel Test
6. List all wheels*
* Option #6 will only be displayed if at least one of the wheels is not displayed.

After selecting the wheel that is being tested, the device will prompt for a ready trigger
Press any key when ready or press DEL to abort test. Hit ENTER from the keypad when
you are ready to run the suspension test.
Note: Before running a test on a wheel, give a shake to the wheel by bouncing the vehicle down
a few times.
Running a push-down test
Push down test can be conducted in two ways:
1. Single Push Method
2. Multiple Push Method (recommended)
1. Single Push Method
In single push method, push the vehicle a hard push and immediately release it, letting the
vehicle bounce up at its natural rate. If the push-down force was large enough for the
suspension meter to sense the trigger, the suspension meter will immediately start
sampling/recording the vehicle oscillation. After over 1.5 sec, the sampling will end and
suspension meter will process the result.

AUTOSTOP™Suspension Meter - User Manual v3.01 Page 6
If the vehicle was not pushed hard enough, or the suspension meter finds some problem
with obtained result, the device will display the following error message:
Abnormal results
obtained!
1. Run test again
2. Abort Test
Select 1. Run test again to redo the test with harder push down force.
2. Multiple Push Method
Multiple Push down method is similar to the single push down test, except the vehicle is
pushed down a number of times to excite the suspension system before pushing a final hard
push. When running a multiple push down test, be careful not to obstruct the upward
bounce of the vehicle. Only push the vehicle down when the vehicle is bounced back to its
top height and then release. Take extra care when making the last push. The last push should
have the maximum force compared with the previous pushes.
Note: Do not obstruct the upward motion of the vehicle.
For better consistency, multiple push down method is recommended.
Results will be displayed on the screen after each test. The meter will ask user whether the
result should be saved. The user can save the test and continue to the next wheel, or user can
redo the test for the selected wheel.
** Suspension rating is evaluated based on Damping ratio., number-of-rebounds, and reference
method used (see section 3.6 & 3.7 for more information).
The graph will remain on the screen until the user presses any key from the keypad. Once a
key is pressed, the device will display the following menu:

3.6 Using Reference Method
Reference method allows results to be generated in reference to the original factory
performance of the shock absorbers. Since different vehicles have different factory ratings
for shock absorbers, it is impractical to have the factory-rating list for the shock absorbers of
all kinds of vehicles and models. Instead, the device groups all vehicles into three categories
and assigns reference data to each category:
Category
(Chassis type)
Standard Reference Data
Front Axle
Rear Axle
Soft (comfortable)
60
60
Normal
70
70
Hard (Sporty)
80
80
The default reference data listed in the above table can be modified in the suspension meter
to adopt the local regulations.
The reference method can be turned off from the configuration menu. To change the
reference data, or turn off reference method, see Section 3.8.

AUTOSTOP™Suspension Meter - User Manual v3.01 Page 10
3.7 Changing Test Parameters
AUTOSTOP™Suspension Meter uses two ways to determine the performance of a shock
absorber. The first method uses Damping Ratio factor and the second method looks at the
number of rebounds of the suspension system. The device can be configured to use both
methods; thereby, the performance of the suspension system using the Damping Ratio
method and the Rebound methods is averaged.
The default calculation method for determining the performance of the suspension system is
using both ‘Damping Ratio’ and ‘Rebound’ methods. Users can change the calculation
method by taking the following steps:
•From the Main Menu, select ‘CONFIG’ by pressing 2from the device keypad.
•Select 3. Result calculation by pressing 3
•Select 1. Calculation Method by pressing 1
•To use the Damping Ratio method only, select ‘1. Using Damping Ratio’
•To use the Rebound method only, select ‘2. Using Rebounds’
•To use both the Damping Ratio method and the Rebound method, select ‘3. Using Both’
•To return, select ‘4. Return’
To quantize and describe the performance of the vehicular suspension system, AUTOSTOP™
Suspension Meter uses a range table for each calculation method. The following table
contains default values or parameters for each method that are used to rate or describe the
performance of the vehicular suspension system.
Rating
Damping Ratio
(zeta, ζ)
Rebound Method
(No. of bounces)
POOR
0 ≤ ζ < 10%
Rebounds > 4
SOFT
10 ≤ ζ < 15%
3 ≤ Rebounds < 4
GOOD
15 ≤ ζ < 35%
2 ≤ Rebounds < 3
HARD
35 ≤ ζ < 100%
Rebounds ≤ 1
Users can change these parameter ranges by taking the following steps:
•From the Main Menu, select ‘CONFIG’ by pressing 2from the device keypad.
•Select 3. Result calculation by pressing 3
•Select 2. Parameter Range by pressing 2
•To change the parameter values for the Damping Ratio method, select ‘1. Set Damping Ratio
Range’
•Or, to change parameter value for the Rebound method, select ‘2. Set Rebounds Range’
•Select the Rating for which you want to update the parameter range using keypad (1-4).
•When an input dialogue box appears, enter the new value and press ENTER.
Users can always revert back to the default parameters, in case of invalid range entries,
