3.Basic Operation

Interface Introduce

(As shown in the figure, the main test interface is divided into several areas such as the menu area, the test item display area, the control button area, and the test timing display area.)

1.Button operation

When you need to perform a certain function, you can directly touch the corresponding button with your finger. If you control the motor to return, touch the “Return” key with your finger, the Route motor and the torsion motor return at the same time, and the test status display area displays the word “Return”.

2.Mode selection

Touch the corresponding menu in the mode selection area to execute the corresponding function. If you touch the “mode selection” key, the mode selection menu will pop up, and you can select the mode. After you select the test mode, the test name and test display area will change accordingly; touch the “parameter” key, and the parameter input interface will pop up >, parameter settings can be performed.

3.Parameter input

When inputting parameters, touch the parameter input box and the numeric keyboard will pop up. Press the input parameter request on the numeric keyboard and touch the corresponding numeric key to enter the parameter. After inputting, press the “ENT” button to complete the input, this input is valid; press the “ESC” button to cancel the input, this input is invalid.

4.Mode selection

In the menu selection area, touch the “mode selection” key, the mode selection menu will pop up, and the test mode can be selected. After selecting the mode, the test name and test result display area will change accordingly.

The selectable test modes are: mode A, mode B, mode C, mode D, mode E, test mode, etc.

5. Parameters Setting

In the <Main Test Interface>, touch the “Parameter” button to enter the <Parameter Setting Interface>.

In the <parameter setting interface>, the test parameters and LCD brightness adjustment can be performed.

1. Test parameters:

1) Route: Route set in test mode, generally 155mm;

2) Angle: the torsion Angle set in the test mode, generally 440 degrees;

3) Times: The number of test periods set in test mode, which can be set arbitrarily;

2. Brightness adjustment:

As shown in the figure above, the LCD brightness can be adjusted in the <System Parameter Setting Interface>. The larger the value, the brighter the brightness.

6.Testing Process

1) Parameter setting

Check the working mode before the test, and reset the mode if necessary.

If it is the test mode, the Route, Angle, and Period of the test mode should be set in the parameter settings.

2) Test preparation

Touch the “Return” button to return the Route motor and the torsion motor to their initial positions.

Clamp the sample.

3) Test

Touch the “Test” button, the Route motor and the torsion motor will operate at the test frequency specified by the standard until the set period number is reached, and the test is over. The two motors return automatically.

Seven. time setting

7.Time Setting

Touch the time display area at the bottom right of the <calibration interface>, and set the system time on the pop-up numeric keyboard.

8.Print test results

In the <Main Test Interface>, touch the “Print” button to print the test results.

9.Calibration

In the <Main Test Interface>, touch the “Calibration” button, and the password input interface will pop up. Enter the password () to enter the <Calibration interface>. (Except for the legal metrology staff, do not enter the calibration state during the use of this system, otherwise the calibration coefficients will be modified at will, which will affect the test results.)

In the <Calibration Interface>, you can calibrate Route coefficients and Angle coefficients. You can also set Route Speed, Torsion Speed, and Half Period, and measure RoutePeriod and Torsion Period.

1) 400 degree torsion time: (QEI is connected to the encoder output of the torsion motor driver during the test)

The time it takes to twist the motor by 400 degrees.

After setting the torsion speed, first return to the position, press the “torsion test” button, and the torsion motor will rotate for a certain angle and then stop. Look at the actual torsion Angle and adjust this value so that the actual torsion Angle is equal to 400 degrees.

2) 440 degrees torsion time: the time required to reverse the motor to 440 degrees.

The test method is the same as the 400 degree twist time.

3) 400 degree return waiting time: this time is the time to wait for returning after reversing 400, which is used to meet the Period requirement of Route 80mm.

4) 440 degrees return waiting time: this time is the time to wait for returning after reversing 440, which is used to meet the Period requirement of Route90mm.

5) Full Period and Half Period: It is used to display the time of Full Period and Half Period during RoutePeriod and Reverse Period tests.

6) Half-Period setting: This value is the waiting time after the completion of the Route depression process, which is half of the full Period to meet the Period setting.

7) Route speed, twist speed:

The pulse value is the Route motor speed and torsion motor speed when the RoutePeriod (45/min) is satisfied.

8) Return parameters: Return Route 1, 2 and return speed 1, 2, with the

return action of Route motor to make the Route value more accurate when the Route motor stops.

Return torsion: cooperate with the action of the torsion motor to make the Angle value more accurate when the torsion motor stops.
