9. Setting key: The user can enter the setting menu through this key on the measurement interface, and press this key to save the data when setting the data.

Seven: User operation instructions

1. Startup display

Startup display welcome and manufacturer information

Display product name, model and version information

2. User main interface display

3. User setting interface

Press the setting key once, as shown below:

Use the up or down arrow to select the setting item. When the setting item is selected to the user, press the setting key to enter the parameter setting interface.

4.Parameter setting interface

In the user setting interface, press the setting key to enter the parameter setting interface, which is displayed as follows:

Setting parameter description: (Taking the maximum torque value as an example)

Use the up and down keys to shift and modify the data. At this time, press the set key to confirm and save the set data (such as pressing the zero key to return without modifying the data). The set data cannot exceed the maximum load value.

(1) Maximum torque value: The user sets the torque upper limit value, which can be set freely as required. When the upper limit value is reached, the number above the parameter name \"torque upper limit value \" flashes, and the buzzer alarms. The upper limit is not higher than full scale.

(2) Minimum torque value: The user sets the torque lower limit value, which can be set freely as required. When the lower limit value is reached, the number above the parameter name \"torque lower limit value \" flashes. The lower limit cannot be higher than the set upper limit.

(3) Setting the minimum storage value: The user sets the minimum storage value according to the storage needs, and data less than this value will not be stored.

Eight, other function description

1. Description of printing function: print data through micro printer.

2. Communication: communicate with the host computer via USB. The communication protocol is MODBUS-RTU protocol.

3. Save data: Save the data during measurement by the save key.

4. View stored data: View the stored data through the View key.

5. Alarm description: When the measured value exceeds the upper limit, the upper limit indicator will be displayed, and the buzzer will also alarm; when the measured value is lower than the lower limit, the lower limit indicator will be displayed. When the measured value exceeds 120% of the maximum load, it may cause damage to the sensor. When \"Overload \" warning prompt appears, the machine will enter the automatic protection state, you must press the zero key or restart the machine. If you can't measure, please long press the set key, enter the password: up key, down key, and press the set key Restore factory settings interface, select Restore factory settings, and press the set key to restore (if unable to restore, please contact the manufacturer).

Twelve Torsion Spring Torque Test Procedures

1. According to the test requirements, select a suitable mandrel and install the mandrel on the mounting holes on both sides of the test head.

Then install the tested spring on the main test mandrel, and fix it at one end through the secondary mandrel.

2. Shake the handle to make the third mandrel contact the other end of the torsion spring, and the force value and angle will be cleared at the same time immediately after contact.

3. The torque value and angle value displayed on the LCD screen are zero.

4. According to the requirements of torsion spring measurement, rotate the measurement handle smoothly and uniformly, and the technical parameters of the torsion spring to be measured can be displayed.

5. Repeat the above operation to verify the technical parameters of the torsion spring.
