The Delta measures the torque at the Target angle.At the end of the test, the Delta display shows the breakaway point and also the torque peak valuereached during the test; the breakaway point is normally lower than the peak value.If the operator goes over the Change Screw value during the residual torque check, a message isshown on the display to indicate that the screw must be replaced with a new one.The LEDs are activated as follows:Low (yellow) LED Torque result below the minimum torque.OK (green) LED Torque result within the limits.High (red) LED Torque result over the maximum torque.The buzzer is activated as follows:Buzzer High tone is emitted if test gives OK result (torque withinthe limits); if not, a low tone is emitted.NOTE: The LEDs and buzzer are activated at the end of the tests.Cycle startTorque min.Torque max.TorqueAngleTarget angleAngle threshold
