11.1.1 Timeout
The “Timeout” defines the end of the test. When the torque goes and remains below the transducer
minimum load (that is normally the 10% of the transducer full scale) for the given timeout, the test
ends.
NOTE: The “Timeout” can be set from 100 ms up to 5000 ms. The default value is 100 ms.
11.1.2 1st threshold (THR 1)
The “1
st
threshold” is used to detect the click point of the wrench.
The torque must continuously decrease from the measured peak at least for the specified value, in
order that it can be considered the click point.
The 1
st
threshold default value is 2%, and it is calculated on the relative torque peak value reached
during the test:
Torque
The test ends when
torque remains under
the transducer minimum
load for the timeout
If torque goes over
transducer minimum load
before the timeout, the test
continues
