4、 Pull out power testing software operation:

Operation steps:

1In the case of first-time use or incorrect configuration saving, it is necessary to manually connect the sensor. By default, select the serial port field in the serial communication areaCOM3Serial port, other options do not need to be changed, then click the connect button to connect to the sensor. If the connection is successful, a prompt "Connection successful" will pop up.

2Before the first use of the device (only before the first use), manual calibration is required. In normal conditions, to prevent misoperation, the sensor calibration area is in a locked state. Click unlock and then calibrate in each direction sequentially. Calibration principle: After opening the calibration for a certain direction, the software will collect the force value of the sensor in that direction in real time and record the maximum value. At this point, input the externally measured force value into the corresponding text box and click 'Finish Calibration' to complete the calibration.

for example: CorrectionYWhen the axis is in the negative direction, click firstYAxis negative direction correction button, then use a push-pull force gauge to correct itYSlowly push in the negative direction of the axis, when the push-pull force gauge value is10-15NStop pushing between them, then enter the value on the push-pull force gauge into the text box, and click 'Finish Calibration' to complete the calibration in that direction. Finally, complete in sequence6Correction in all directions is sufficient.

3Before testing a certain type of product for the first time (a product that does not exist in the configuration document), it is necessary to set the starting point of the measurement path for that product. Step by step is to first smoothly install the tested product on the fixture, adjust the knob to the starting position, and then manually adjust the side head to the appropriate position above the knob. Click to set the starting point.

4After replacing with other types of printing paper, it is necessary to reset the printing size. in compliance withpicture1As shown, simply enter the size of the receipt in the text box. be careful:XFor the width of the receipt,YThe sum of the height and spacing of the receipts.

5Before testing a certain type of product for the first time (a product that does not exist in the configuration document), it is necessary to set the measurement path for that product. Directly in“picture2”Just fill in the horizontal and vertical strokes.

6After setting the product parameters, if you need to measure this product frequently, you can save the configuration. In“picture2”Enter the product name and then proceed to“picture5”Enter the product name and click add. After successful addition, the product you just added can be seen in the existing product dropdown menu. At this point, the parameter setting process is over.

7Before each operation, confirm that the air outlet knob is in the starting position and that the side head returns to the origin first. Click to run, the device will move along the pre-set path and collect charts during the processpicture4”It will be displayed in real-time“picture2”The force value of the sensor with the selected direction. After the test is completed, the maximum and average values of the measurement results will be displayed below the chart, along with a data statistics table“picture3”We will record the result（TipsIf the result is incorrect, right-click and double-click on the header to delete the record. ）. If“picture2”The 'Print Results' option has been selected, and the printer will automatically print the results after the test is completed.
