Term Description
Accepted Data Data that fall within the acceptable limits in a fastening strategy.
Angle Angle that is to be reached at the end of the fastening sequence
(also final angle, rated angle, or nominal angle).
Angle Capability Indexes Measure of acceptable variation of final angle values in a fastening
process.
Angle Control Fastening strategy by which you are controlling a tool by predeter-
mined angle limits.
Angle Encoder Device that measures the angle of rotation.
Angle High Active if final angle > angle high limit.
Angle High Limit (AHL) Maximum admissible angle of rotation for a fastening stage.
Angle Limits Range between the maximum and minimum acceptable angle for
one cycle.
Angle Low Active if final angle < angle low limit
Angle Low Limit (ALL) Minimum acceptable angle for a run cycle.
Angle Monitor Fastening strategy by which you are monitoring a tool by predeter-
mined angle
Angle Reject Cycle rejected when the acceptable angle is not achieved.
Application Programmed setting of the tool for a specific fastening sequence of
up to 6 stages.
Application Select 0-7 Application selects 0-7 are used to select applications 1-99using a
binary count of 0-7 where app. sel. 0 is the least significant bit.
Baud Rate Frequency at which the unit communicates.
Capability Index (Cpk) An index combining the process potential and the measure of the dif-
ference between process and the specification mean. CPK will equal
Cp if the process mean is centered on the target (nominal) specifica-
tion value. If CPK is negative, the process mean (X-Bar) is outside
the specification limits. If CPK is between 0 and 1, then some of the 6
sigma spread will fall outside of the specifications. If CPK is larger
than 1, then the 6 sigma spread is completely within the specification
tolerance.
Capability of Process (Cp) Ratio of the process tolerance to 6 standard deviations. Ranges from
0.0 to infinity with larger values indicating a more capable process.
(Often referred to as Process Potential Index or Inherent Capability
Index.)
Cycle Complete Active whenever tool is not running.
Cycle OK Run cycle within limits.
Default Parameters Parameters automatically selected by the unit.
Desired Final Torque Final torque desired in a fastening process (referred to as torque set
point).
End Delay Time (ms) Delay from the time the tool is switched off until measurement stops.
Engineering Units Units of torque measurement
External Transducer Transducer physically located on the outside of the tool
Fastener Rotation Direction in which a fastener rotates
