The common faults and troubleshooting methods that may occur during the use of the adhesion tester are as follows:

1、 Unstable accuracy

reason：

• Sensor zero bias or aging leads to inaccurate measurement data.
• The instrument has poor sealing, and the sensor's performance is affected by dust or moisture.

exclusion method：

• Regularly calibrate sensors to ensure they are in normal working condition.
• Check the sealing of the instrument, promptly clean dust and moisture, and keep the interior of the instrument dry and clean.

2、 Sensor calibration failure

reason：

• Long term use or external impact of sensors can cause changes in calibration parameters.

exclusion method：

• Re calibrate the sensor to ensure the accuracy of the measurement data.
• During the calibration process, follow the instructions in the operating manual to ensure the accuracy of the calibration parameters.

3、 Environmental factors affect measurement

reason：

• Environmental factors such as temperature and humidity have a significant impact on the measurement results.
• The unstable testing speed leads to fluctuations in the measurement data.

exclusion method：

• Strictly follow the standard conditions to ensure a stable testing environment.
• Control the testing speed and maintain its stability to reduce measurement errors.

4、 Data processing software malfunction

reason：

• The software version is outdated or has vulnerabilities, resulting in incorrect result reading or inability to record data.

exclusion method：

• Timely check and update data processing software to ensure it is at the latest version.
• Before updating software, backup important data to prevent data loss.

5、 Improper operation leads to measurement errors

reason：

• The fixture is not firmly fixed, causing the sample to move or fall off during the testing process.
• The testing speed is unstable, such as too fast or too slow, which affects the measurement results.

exclusion method：

• Ensure that the fixture is securely fixed to prevent the sample from moving or falling off during the testing process.
• Control the testing speed and maintain its stability to reduce measurement errors.

6、 Instrument hardware malfunction

reason：

• Long term use or external impact of the instrument can cause damage or aging of hardware components.

exclusion method：

• Regularly inspect the hardware components of the instrument, such as sensors, power systems, etc., to ensure that they are in normal working condition.
• For damaged or aged hardware components, replace them with new ones in a timely manner to restore the normal function of the instrument.
