The steps of system debugging and verification of the compression testing machine are as follows:
First, system inspection
1. Ensure that the connection between the computer and the compression testing machine is normal.
2. Determine whether the testing machine is in normal operation.
3. Run [WinYaw] to enter the main window after registration. Press the [Hardware Reset] button in the main interface. If the force value changes, it indicates that it is normal. If the force value cannot be reset, check whether the cable is properly connected.
4 in the above steps if there is no abnormal situation, it means that the control system of the testing machine has been successfully connected. Otherwise, if there is an abnormal situation, please contact the supplier or technical personnel.
Second, system debugging
After determining the normal control system of the compression testing machine, you can begin to adjust the test configuration parameters.
As a metering equipment, in the annual inspection of the metering department, if the user finds a large difference between the reading displayed by the program and the value indicated by the force ring, the user can also modify the debugging parameters until the measurement requirements are met.
1. Hardware zero
Switch to minimum gear and click the hardware zero button at the lower left corner of the test force display panel until it reaches zero. Hardware zero all gears are consistent
2. Software zero clearing
Switch to maximum and click the reset button at the lower right corner of the test force display panel.
3. Verification test force
Click [Setting]-[Force sensor verification] to open the verification window of missile force sensor (password 123456). Users can adjust the display value in two ways:
One-step calibration: input the standard value into the text box in the window. When the standard dynamometer is loaded to the standard value in the text box, press the [calibration] button and the display value will be automatically calibrated to the standard value. If the displayed value is not correct, you can click the “calibration” button again and calibrate again.
Step by step calibration: In the case of small deviation between display value and standard value, if the display value is too large, please click load [-] button or hold on (gain fine tuning value will keep getting smaller); If the display value is too small, click or hold the load [+] button until the display value is equal to the standard value of the force ring.
Note: after correction, please click the [OK] button to save the correction parameters. When users change and debug other measuring gears, there is no need to close this window. It can automatically track the switching changes of gears and record the fine tuning values of each gear.
When modifying the gain fine-tuning parameters of each step, the average value of the gain fine-tuning parameters of each detection point in the first step can be taken, so that the measurement accuracy can be higher (because it will not be biased to one side).
When adjusting the load display value, please adjust from the maximum gear, the adjustment of the first gear will affect the following gears. When not graded, the first correction of linear adjustment, and then correction of nonlinear correction points. Because the sensor measures the force, the fine tuning value of the lower gear is adjusted based on the fine tuning parameter of the first gear (or full range point).
