GLOSSARY OF TERMS
Configure
The process of entering and storing the basic parameters which
determine the resulting outputs of Expert Torque Wrench.
Cycle End Time
Is the time the torque must be below threshold for the reading
to finish.
Custom Configuration
A tightening configuration and associated setup parameters
programmed by the operator and saved for future use.
Direction of Rotation
The direction in which the wrench is turned to apply torque-
Clockwise (right) or Counter-clockwise (left).
Max Angle Time
The amount of time the wrench will continue to measure a “slow”
reading (i.e. an angle increase of less than 4 degree per second)
before ending a measurement.
Peak
A type of measurement which records the highest torque applied
to a transducer during an operation.
Sample
Individual torque reading.
Span
The Span is the effective operating range of the wrench. This is
the range between zero and the maximum design limit of the
transducer.
Subgroup
A collection of samples taken using the same setup configuration.
Threshold Torque Value
The level of torque which a signal must rise above and then fall
below to be considered a valid torque cycle. In the Expert Torque
Wrench, this has a minimum setting of 5% of the rated span of the
transducer.
Torque Cycle
A complete application of torque to a joint starting from the torque
rising above the preset threshold value and finishing at the preset
cycle end time.
Torque Limits
The upper and lower limits for the torque application.
Torque LSL
The Lower Specification Limit as set in the setup parameters.
Torque USL
The Upper Specification Limit as set in the setup parameters.
Torque / Angle Gradient
The slope of a torque vs. angle curve. It describes the amount of
torque increase for every degree a bolt is tightened. The Expert
Torque Wrench monitors this value to recognize the yield point.
Trace
A graphical representation of the torque cycle.
Track
A type of measurement which follows the changing torque
values imposed on a transducer as torque is applied. The display
will return to zero after the torque is removed.
Units of Measurement
It is possible with Expert Torque Wrench to measure torque, and
convert internally to display and store in any of the other torque
measurement units as specified.
