5.
Set up the correct folder to store the data files by entering a filepath in the “Test Data
Location” field. Use a folder name that identifies the engine owner or the customer. A drop
down menu will show the previous ten folders used. A browse button is provided to search
for a folder. The folder location can be anywhere on the computer but it is best to keep
them together with other WinDyn files.
6.
Check for the correct vehicle and test specifications. If the specifications are wrong, enter
the correct specifications by selecting the channel and press enter (or click on the channel
name). Specifications can also be saved and installed with a saved Specification file.
See Chapter 3, section 3.2 in the WinDyn Users Guide for more
information on Specifications. Chapter 9 in this manual gives specific
details on each specification channel and how it is used by the system.
7.
Enter Test Notes. These notes can include such things as details on the test engine,
contact information about the owner, reasons for testing the engine, results of the test, etc.
The entered information will be saved with the stored “test data” files (*.SFD). Once the
data is stored, additional information may be later added to the file via the F10 key using
the Stored Data Viewer program. See Chapter 4 the WinDyn Users Guide for more
information on test description notes and data analysis.
8.
Press F2 or click on “Activate” to install the new test settings.
9.
The dyno sensors should be zeroed before the car is rolled onto it. Once on the dyno, the
load cells will read a torque while the roll brake and/or vehicle brakes are applied. Once
these brakes are released, the torque readings should go back to zero as the car will now
be restrained by the straps.
If the system is calibrated properly as directed in Chapter 10, a zero
reference offset will be included in the calibration file (*.CAL). If and when
the calibration file is installed when a Test Group (*.TGP) is opened, all
sensors will automatically be zeroed. However, in situations of extreme
atmospheric pressure changes, the zero reference may be off. For more
information on Calibration files, see Appendix A in the WinDyn Users
Guide.
To zero the sensors, press
Autozero
on the handheld (the “F” key). Then press
All
Channels
(the “B” key). This zero reference will be good for hours.
10.
Load the vehicle on to the dyno; see section 6.4 for instructions. If using nylon straps,
insure none of them are near any hot surfaces or they might melt. Also, make sure they
are not near any rotating parts.
11.
Select a method for obtaining engine speed. See Section 6.8 for information and Section
6.9.4 for the procedure.
12.
Connect any additional sensors to the vehicle. Place the Temp/Humidity probe in the air
stream of the air intake or in its normal location (to get repeatable results the probe should
be in the same location for every test).
