1. Each time you turn on the instrument and start a new set of tests, you must press the reset button to restart the instrument, otherwise the data processing will be incorrect.

2. When the instrument is reset and the zero key is pressed, it contains the function of automatically clearing (peeling) the force sensor. Please note that when starting the instrument, the upper clamp should not be subjected to any additional force except its own weight, otherwise, inaccurate peeling will lead to inaccurate testing.

3. The instrument input setting parameters should be performed before a set of tests begins, otherwise, data processing errors will occur.

4. The instrument has been calibrated for the strong force indication before leaving the factory. Non-professional calibration and maintenance personnel are not allowed to calibrate it arbitrarily, otherwise the instrument will cause inaccurate force measurement.

5. The force sensor can be cleared while waiting for the test and calibrating the display status. After pressing the zero key, wait 2 seconds before starting the test.

6. In the instrument automatic control program, there is a test value judgment program, which will automatically delete the obviously wrong test data (including the measured value after the sensor zero point drifts seriously and the impact strength value); please note that if the instrument automatically deletes the current test value for many times in a row, it is generally because the reset value has been offset. You should press the reset key to reset it again before continuing the test.

7. The maximum allowable setting of the sample value and the number of sample varieties of this machine are limited to 255 times. At the same time, the number of samples × the number of samples <500, the computer automatically determines whether it is a memory overflow and prompts with text on the LCD screen.

8. If you want to print the test curve, you should print it after the current test is completed, that is, only print the current test curve. If this test is the last test of this group, print the curve first and then print the report.

9. Note that the force on the upper clamp should be less than the full scale value of the instrument. Avoid the impact of the upper clamp, otherwise it is easy to damage the force sensor.

10. Clean and maintain the instrument well, and lubricate the screw and guide rod in time.

11. Regularly calibrate the instrument to ensure the accuracy of the instrument's measurement value.

12. Non-professional maintenance and calibration personnel are not allowed to dismantle the instrument. The measurement performance must be calibrated after each dismantling to avoid instrument inaccuracy.

13. If there is a sudden failure during operation, emergency stop must be performed and restart must be performed.
