.>. According to the size of the specimen, the distance between the two knife edges should be adjusted first.
.>
.>. Install benchmarks on the left and right main bodies and tighten the stop screws.
.>
.>. Adjust the position of the upper knife edge so that the distance between the upper and lower knife edges is equal to the required gauge length value.
.>
.> Loosen the table screws, install them on the left and right bodies respectively according to the left and right table numbers in the product certificate, and then adjust the position of the table so that the bottom surface of the lower blade is in contact with the screws on the base plate. Contact, the top is in contact with the measuring plane of the scale.
.>
.>Pinch the even compression springs at both ends of the right connecting plate and fixed plate with both hands to increase the distance between the two knife edges.
.>
.> When measuring compression deformation, after the instrument clamps the test piece, unscrew the positioning screw away from the bottom surface of the lower blade. When measuring tensile deformation, there is no need to unscrew the positioning screw. Still maintaining horizontal contact with the bottom surface of the lower blade.
.>
.>. In order to enhance the clamping force of the upper knife edge, the clamping frame needs to be adjusted on the benchmark pole. Its position should be as close as possible to the upper knife edge. The clamping force can also be adjusted through the spring cap.
.>
.>. The compression amount of the specimen within the gauge length range is calculated by taking the average of the values in the two tables.
