Adjusting the Tensile Tester Display Error
1. The positive deviation of the display is outside the tolerance.
Adjustment method: After making sure that the installation height of the instrument meets the requirements of the regulations, first check whether the friction force of the working part is too large. If this is the case, adjust the play of the guide wheel in order to eliminate the frictional force. If necessary, clean the working cylinder. If the error is still positive after the influence of the frictional force has been eliminated, loosen the fastening screw between the pendulum rod and the pressure plate in the force measuring part (reading mechanism), adjust the pressure plate inwards and pull tighten the fixing screw. If the small scale is qualified, but the large and medium scales still noch are out of tolerance, the weight of B-thallium and C-thallium should be increased accordingly until the test is qualified.
Secondly, the negative deviation of the display is out of tolerance.
Adjustment method: First check whether the load cell is installed correctly and whether the friction force is too large. Bad, the weight of B thallium and C thallium should be reduced accordingly until the test is passed.
Third, the display error on the dial appears Front positive and then negative or front negative and then positive and some points are out of tolerance.
Adjustment Method: At this time, the pusher plates aree and teeth should be changed The angle of the contact surface of the rod head The contact surface is usually fixed on the surface of the pressure plate by a flat steel sheet by two upper and lower screws The upper or lower side between the steel sheet and the pressure plate (can only be placed on one side be used) to change the angle and the adjustment is repeated until qualified.
