Operation steps before testing

1. Before using the torque screwdriver tester, check whether the power of the instrument is sufficient. If the power is insufficient, charge it first (you can also use the instrument when charging).

2. Under normal circumstances, turn on the power switch and the displayed value is zero. If it is not zero, press the \"Clear \" key to clear the value.

3. Before testing, you need to set the upper and lower limits, minimum storage value, minimum peak hold value, automatic peak time, automatic shutdown time, gravity acceleration, etc. The specific operation steps are as follows:

a. Upper limit value setting: The user sets the upper limit value, which can be set freely according to the needs. When the upper limit value is reached, an audible and visual alarm is automatically issued. The upper limit value is not higher than full scale. On the measurement interface, press the\"Settings\" key to enter the setting interface, select \"Upper limit value setting\", press the\"\" Setup\"\" key to enter the\"Upper limit value setting\" interface, and press \"\"Key to change the value, press \"\"Key to change the number of digits, set the required value, press \" Save \"key to return to the setting interface, the lower limit setting is the same as above. (The maximum value for the upper and lower limits is 10, the minimum is 0)

b. Lower limit value setting: The user sets the lower limit value, which can be freely set as required. When the lower limit value is reached, an automatic light alarm is issued. The lower limit value cannot be higher than the set upper limit value. Specific settings are set as the upper limit.

c. Minimum storage value setting: The user sets the minimum storage value according to the storage needs, and data less than this value is not saved by the peak value. Select \"Minimum Stored Value \", press \"Settings \" key to enter, also use \"\"Key and \"\"Key to set the required value, press \" Save \"key to return to the setting interface (the minimum stored value is set to a maximum of 10 and a minimum of 0).

d. Minimum peak hold value setting: The user needs to set freely according to the peak value. The automatic peak measurement needs to be set freely. Data less than this value is not saved by the peak value. Enter the \"Minimum Peak Hold Value \" interface, also use \"\"Key and \"\"Key to set the required value, press \" Save \"key to return to the setting interface.

e. Automatic peak time setting: The user can freely set the time that the peak value needs to be held in the automatic peak measurement state from 1 to 99 seconds. Enter the \"Automatic Peak Time \" interface, also use \"\"Key and \"\"Key to set the required value, press \" Save \"key to return to the setting interface.

f. Automatic shutdown time setting: In the non-operation state, the automatic shutdown time can be freely set from 0 minutes to 9 minutes (when set to 0, it means to cancel the automatic shutdown). Enter the \"Automatic shutdown time \" interface, use \"\"Key to set the required value, press \" Save \"key to return to the setting interface.

g. Gravity acceleration setting: The user can set the gravity acceleration value according to the location of the area. The default gravity acceleration value of this machine is 9.794). Enter the \"gravity acceleration \" interface, use \"\"Key and \"\"Key to set the required value, press \" Save \"key to return to the setting interface.

h. Restore the initial settings: Improper user operations or multiple changes to the data appear confusing. You can use this setting to restore the data from 1 to 7 to the factory state. Enter the \"Initial Settings \" interface, and enter the password to complete the setting.

Seven, test steps

1. Adjust the torque value of the tested preset torque driver to a preset value.

2. Shake the upper hand wheel to adjust to the proper height, put the top of the screwdriver into the upper connector

3 Shake the lower hand wheel to adjust the lower connecting body to a proper angle, put the bottom end of the screwdriver in and fix it.

4. Switch on and select the unit and measurement mode as required. (Generally select the peak measurement mode)

5. Turn the lower hand wheel clockwise to apply force. The value displayed on the screen of the instrument is the measured torque value.

USB output

The instrument communicates with the host computer via USB. The communication protocol is MODBUS-RTU protocol. The specific connection method between the instrument and the software is as follows:

1. Connect the instrument and the computer with a USB data cable.

2. Turn on the power of the instrument so that the instrument is in the measurement interface.

3. Put the supplied CD-ROM into your computer's CD-ROM drive and open the serial port software path: CD-ROM \ aliyiqi \ AutoTest.exe.

4. Click the\"System\" button at the bottom of the software window to pop up the\"System Settings\" dialog box. Select the corresponding serial port in the communication port from the computer. The specific operation steps are as follows:

③ Return to the\"System Settings\" dialog box popped up by the software, select the corresponding serial port number in the communication port (the analogy is\"\" 5 \"), and then press OK, as shown in the figure below:

④ Close the software and double-click AutoTest.exe again to check whether the serial port is connected. There are several ways to check it: Apply a point force on the sensor of the instrument and check whether the torque value at the top of the software window corresponds to the jump. A bounce indicates that it is connected, otherwise the opposite is true.

① Click the\"Settings\" button at the bottom of the software window to bring up the\"Parameter Setting\" dialog box and fill in the corresponding data according to the test needs. The specific parameter size is as described in step 6-3-b. After filling it out, just press the\"OK\" button. After the setting is successful, the data displayed at the bottom of the software window will change accordingly.

② Make sure the serial port is connected first, and press \"Start \" button for synchronous test.

⑦ After the test is completed, press the\"Stop\" button and click\"Save\" or\"Stop\". Save to save the test curve into the software, and vice versa when stopped.
