Resolution resolution
In the measurement range, the minimum value of the measured value measured by the bar is expressed as a percentage of the full-scale output.
3.3
Lag hysteresis
Backlash
Hysteresis
When the input amount is full-scale change, for the same input, the positive and the reverse stroke of the steel bar are the maximum of the actual average characteristic curve output
