Setting Up Torque-Angle Measurement Modes
In using the torque-angle or "turn-of-the-nut" algorithm, a
fastener is run down to a specified clamping torque and then
rotated an additional number of angular degrees regardless of
the torque necessary to turn it. A typical fastener specification
might read: "15 ft lb & 50° rotation." For additional information,
refer to the Torque-Angle Tutorial Quick Reference card that
accompanies this manual.
When setting up torque-angle measurement modes:
• Angle measurements are not stored and cannot be printed.
• CLEAR, STORE and SEND must be set to MANUAL in the
ANGLE mode. For additional information, refer to
Programming AUTO CLEAR in this chapter.
• Torque SET HIGH must be set above the maximum torque
expected. For additional information, refer to Setting Up High
and Low Limits Alert in this chapter.
Setting Up the Torque/Angle Algorithm
When in the ANGLE mode, use SET LOW to preset the 2000-
810-01 to a clamping torque. At torque preset coincidence
(when the input torque matches the SET LOW preset value),
the 2000-810-01 momentarily sounds an alert and automatically
switches to measure angle from zero degrees. Preset the
maximum angle using the SET HIGH function. A pulsating alert
sounds at angle preset coincidence (when the measured angle
matches the SET HIGH maximum angle preset value). SET
HIGH torque preset also is active in the angle mode to protect
the wrench from over-torque.
Set Up Torque-Angle Algorithm
Use the following procedure to set up the torque-angle
algorithm.
1. Select ANGLE mode using MODE.
2. Press SET LOW.
— The LED display shows the previously programmed
clamping torque preset value.
— The LCD display reads:
Clamping torque - upper line
[units] - lower line
