Bag tensile testing machine use and test method

Bag tension testing machine use method:

1. Operation Panel Key Description Clear key is used to clear the previous test result and zero point. The storage key is used to store the test result. The machine is designed to calculate the average of five times and store up to five test results. The correction key cooperates with the shift and clear keys for on-site calibration.

2. Speed ​​selection and operation control The user can select the appropriate gear according to different test standards. If there are special requirements, he can adjust it by himself. Before adjusting, he needs to contact the technical personnel of the manufacturer to prevent confusion. The “raise” and “down” keys control the carriage return and tension of the beam table. The stop button controls the stop position of the table.

3 , the adjustment screw above the stroke switch top rod, you can determine the starting position of the lower fixture.

4 , bag tensile tester test method:

(1) According to the test requirements to choose the stretching speed

(2) Hold the test piece in the middle of the upper and lower clamps. Do not distort the test piece.

(3) Press the Clear key. The display turns from red to green. During the test, all data displays are cleared.

(4) Press the down button to lower the lower jaw uniformly

(5) After the specimen breaks, the lower chuck stops descending, and at the same time, the meter automatically maintains the maximum force value and extension length, and the real-time force value is zero.

(6) Press the memory button to save the test results

(7) Press the up key to return the lower chuck to the starting position.

(8) The same average of five tests can be automatically calculated.

(9) The power should be turned off promptly after the test is completed. Note: When the meter displays “stop” Note: When the meter displays “stop”, the real-time force value may not be zero, press the clear key to clear the real-time force value may not be zero, press the clear key to clear it. Affect the accuracy of test data. At the same time, the lower chuck cannot move downwards. Does not affect the accuracy of the test data. At the same time, the lower chuck cannot move downwards.
