　　G308 Double Pendulum Tear Strength Tester uses the Elmendorf method to measure the tear strength of various fabrics and evaluate their tear resistance performance.

　　Compliant with standards:

　　ASTM D1424 D689;NEXT 17;M&S P29;BE EN ISO 13937,4674;BS 4468;DIN EN 21974;GB/T 3917.1;ISO 1974

　　Operation:

　　Firstly,prepare the accessories and test samples;

　　2.Turn on the instrument switch and enter the LCD screen operation interface;

　　3.Select the appropriate test range according to the testing requirements;

　　4.Place the corresponding weights on the instrument bearings;

　　5.The system automatically calibrates the weight of the weights;

　　6.Press the buttons on both sides of the bottom of the instrument simultaneously;

　　7.Rotate the double pendulum;

　　8.After calibration is completed,enter the testing interface and click on"Test";

　　9.Cut the sample according to the sampling template and install it in the fixture;

　　10.Cut a tongue shaped small opening on the sample;

　　11.Simultaneously press the buttons on both sides of the bottom of the instrument;
