6.4 Special Functions
6.4.1 One Pulse Reverse Function
One Pulse Reverse is used in applications where socket to fastener tolerances allow the fastener
to “stick” or lock into the socket during fastening operations. Upon completion of fastening, torque
is applied in the reverse direction for the full time specified by 1 Pulse Reverse Time, at the speed
specified by 1 Pulse Reverse Speed, allowing the socket to free itself from the fastener. This is
done without affecting the torque originally applied to the fastener by setting the 1 Pulse Reverse
Torque Limit to a lower Torque value.
