Nonlinear velocity correction function instruction:
Nonlinear velocity correction function adopts below low velocity(0.5m/s) linear correction
in principle. It has eight section correction including eight velocity point and eight
correction coefficient.
Nonlinear correction coefficient means to be revised base on the original sensor
calibration coefficient. So please turn off nonlinear correction function and mark the
sensor factor, then turn on the function. According to nonlinear section of sensor,
measuring the velocity and correcting the setting. If the setting is suitable, no need to
calibrate.
Suppose: The original velocity is rate which has been calculated according to sensor
factor. The correcting velocity is rate which has been nonlinear corrected. Then the
velocity after correction has correspondence as following;
Notice: When setting velocity, please keep the relation as following:
Velocity 1>Velocity 2>Velocity 3>Velocity 4>Velocity 5.....>velocity 8
