Sensor I® Expert User Manual
1. Set the snug torque to approximately 50% of the expected final torque
reading.
2. Set the capture angle (see chart).
3. The operator must then pull the wrench approximately 30° over a period
of no more than 2 seconds. Pulling the wrench past the desired audit
angle will not have an adverse effect on the audit reading - it will be
"captured" at the correct audit angle. The captured torque can be viewed
when the parameter shown on the display is "Tq".
*The grip length is the total length of the bolt located within the assembly
pieces. Keep in mind that adding socket extensions will also call for an
increase in angle.
This chart is offered as a guideline only. The optimum value for the capture
angle will be influenced by the overall joints stiffness, joint configuration,
and frictional conditions. Application testing is recommended to determine
the most accurate value for the specific joint under audit.
