# YM - Manual Tighten to Yield

This step guides the user until the yield point of the joint is reached.

Parameter | Description
--- | ---
Target angle | If > 0, after detecting the yield point the operation continues until the angle reaches the Target angle value. This configuration is commonly used for production operations. If = 0, the operation stops when the yield point is detected. This configuration is commonly used for joint analysis in quality control operations.
Ratchet time | Starts when the torque goes below the Rundown complete torque without reaching the 3rd percentage value. This allows the operator to release the torque for a while and recharge during the tightening operation. Default value: 5 sec. Minimum value: 0.1. Maximum value: 30 sec
Linear slope coefficient | Defines the joint stiffness in the linear part of the curve. It is meant as torque/angle slope and is measured in Nm/°. Default value: 0.5. Minimum value: 0.1 (also suitable for very soft joints with a ratio less than 0.1). If the selected unit of measurement is different from Nm, the Linear slope coefficient must always be converted into Nm/°.
Torque correction coefficient | When extensions are used, the wrench measurement might be compensated to show a more accurate torque value. To calculate the correction coefficient, please refer to How to calculate the Torque Correction Coefficient. The parameter is stored in the RFID TAG of the end fitting tool. When extensions are not used, Torque correction coefficient = 1.
Angle correction | When extensions cause additional wrench bending, the wrench angle measurement can be compensated to show a more accurate angle value. To calculate the correction value, please refer to How to Calculate the Angle Correction. The parameter is stored in the RFID TAG of the end fitting tool. When extensions are not used, Angle correction = 0.
