6. Operation process

(1) Adjust the level of equipment installation and positioning of machine feet;

(2) Install the sample at each station, fix the sample with the provided butterfly screws, and adjust the sample level;

(3) Connect the power supply and turn on the power. Note that the equipment should be properly grounded to prevent electric shock accidents;

(4) Impact test:

1) Fix the force-applying circular steel plate on the force sensor; for static pressure testing, use a ø160mm circular steel plate; for impact testing, use a ø300mm circular      steel plate;

2) Adjust the position of the sample and the force-applying steel plate by pressing the manual button in the parameter and debugging pop-up window and adjusting the air  pressure according to the output force value. After the adjustment is completed, return the cylinder to its original position.

3) Enter the operation interface and press [Force Value Zero] to reset the current force value;

4) Set the B station function to the function to be tested, clear the last count, and set the force value, number of times, and force application time;

5) Press the [Start Test] button in the main operation interface, and the device will automatically perform opening and closing tests and automatically count the times;

6) The test will automatically stop when completed and will be displayed in the prompt  box; if you need to stop during the test, press the [Stop Test] button; if you need to   stop urgently, press the emergency stop button;

7) Remove the test completed samples and inspect the samples.

(5) Swing Test:

1) Adjust the position of the sample and the force-applying steel plate by pressing the manual button in the parameter and debugging pop-up window and adjusting the air  pressure according to the output force value. After the adjustment is completed, return the cylinder to its original position.

2) Enter the operation interface and press [Force Value Zero] to reset the current force value;

3) Clear the last count on the main operation interface and set the force value, number of times or application time;

4) Press the [Start Test] button in the main operation interface, and the device will automatically perform opening and closing tests and automatically count the times;

5) The test will automatically stop when completed and the message will be displayed in the prompt box. If you need to stop during the test, press the [Stop Test] button. If    you need to stop immediately, press the emergency stop button.

6) Remove the test completed samples and inspect the samples.

7. Precautions and Maintenance

(1) Ensure that the machine is well grounded to avoid safety accidents.

(2) Do not exceed the allowable load during testing to avoid damaging the pressure sensor.

(3) The machine part should be wiped frequently to keep it clean.
