The wrench detected double tightening
because the tightening rotated angle has
been lower than the setting angle.
In this case, wrench does not send signal
once set at double tightening signal OFF.
Conduct correct tightening or reduce the
setting angle to release this error.
Insert and remove the battery to reboot the
transmitter and immediately stand still it.
It can be used once the error is released.

ask to repair.

not completed.
To release this error, complete the
tightening until reaches set torque or stand
still the wrench for 1 minute.
Try tightening and if the error shows again,
