Operation problem one: During operation, there is suddenly no curve graphic on the display screen
There is no curve display during the experiment: the reason for this problem may be:
1: The coordinate selection for the software curve graph is incorrect.
2: The test speed is slow, and it has not reached the pre load setting value, so the recording of test data has not started.
3: Select curve graph coordinates
4: Set the test speed or set the preload to ON

The solution is as follows:
1: Insert the extensometer to be used onto the control board
2: Reconnect and select the correct extensometer
3: Replace the communication line of the extensometer
4: Replace the extensometer and recalibrate the extensometer.

Operation problem 2: Sudden shutdown during operation
Sudden shutdown during the experimental process: The possible cause of this problem may be:
1: There are issues with the experimental plan settings.
2: Static interference.

The solution is as follows:
1: Check whether the shutdown conditions, fixed force, positioning displacement, fixed deformation, and fixed time in the basic parameter settings of the test plan are correct for the equipment.
2: Connect the mainframe of the testing machine to the casing of the computer and ensure that the grounding wire of the mainframe is not charged.

Besides two issues, it is more important to know how to maintain the fixtures of the tensile testing machine in order to use it for a long time.

Maintenance method of tensile testing machine fixture
1: Regularly inspect the fixtures for any damage.
2: Regularly check whether the pressure gauge accurately records the air pressure and oil pressure of the clamping device.
3: If the clamping surface is worn, damaged or stained, it should be replaced in a timely manner.
4: Do not use clamping force exceeding the required level, as long as it can provide reliable, non sliding fixation.
5: The sample clamped in the fixture should always be attached to the load sensor.
6: Preheat the load sensor for at least 15 minutes.
7: Once the specimen is clamped in the appropriate position, do not change the balance or beam position control point again.
