Double pin data retention, light reading. Horizontal use, two-way measurement: benchmark control positioning, strictly grasp the quality of production. Portable design concept: compact portable card style. During the test, just use the stylus to pull the object to be tested and move it from the static state to the desired position. The tensiometer can be tested either clockwise or counterclockwise, but the stylus arm must always be perpendicular to the direction of the pull. After the maximum value is measured, the driven needle stops moving, so that the tester can read the peak value.
