If the wrench angle feature is ticked and it contains a Gyro, then the wrench can
measure angle. To measure angle, the wrench must first establish a zero datum, i.e.
a condition, where the wrench is not turning. This always needs to be performed
when the wrench is turned on. It can be performed in 2 ways:
Use the
Zero Gyro
function on Main Menu. The Red LEDs will turn on as a
warning and the wrench should be kept still for 10s while the zeroing occurs,
e.g. by laying the wrench on a bench. If the wrench detects that the wrench is
not stable but being moved, then it will re-do the zeroing process, displaying
the message “
Initialisation: Angle Not Steady
” and it will repeat the zeroing
function, until it is abandoned or passes. It is a requirement that there must be
a good zero result before angle measurement can occur.
When entering a torque measurement screen that requires angle, for the first
time. This will also start the same Zero Gyro process, if enabled in Gyro menu.
Once the Gyro has been zeroed, that result is remembered while the wrench remains
powered.
It is also possible to repeat the zero Gyro function at any stage.
The Gyro will work down to ~ 0.5 deg/s. Below this angular velocity, the angle may
not increment properly.
The Gyro will work up to ~ 300 deg/s. Above this angular velocity, the wrench will
display the error message “
Pull too fast
”. It will remain until acknowledged by Red
or Green
key. The wrench will then re-zero the Gyro and initialise ready to
start the torque measurement again. In Sequence / Too Fast Limit the user can
change maximum gyro speed. In Too Slow Limit the user can set the time within
which the pull must occur to be valid.
Angle is only measured in the direction stated. If ratchet against this direction, then
the angle will not change.

This sets the time that the wrench waits, after the torque falls below torque threshold,
