1.Adopts original and fast-response electromagnetic force balance sensor and microprocessor intelligent control to improve measurement accuracy and linearity;
2.Only one calibration point is required, no need of zero adjustment potentiometer and full range potentiometer;
3.Integrated temperature detection circuit and automatic temperature compensation of the test results to avoid the impact of temperature on the tension value;
4.Automatically zeroes, measures, calculates, displays print results, and 300 pieces of measurement results can be stored;
