●Rate Check
Three rates can be used to monitor the fastening operation during the fastening operation.
A rate start torque (angle) and a rate end torque (angle) are set and the torque slope (slope of the
torque vs. angle) between the two points at the point at which the rate end torque (angle) is attained is
measured to make the judgment. (Example: 25N•m÷100deg=0.25N•m/deg).
The fastening operation is ended when the measurement value of each rate falls outside the the high
and low limit ranges.
The start torque (angle) and end torque (angle) of the respective rates can be set freely without any
relation to the order of the rates and the set values of the other rates.
* Since there are notes on rate determination on the next page, please read one.
