Double Hit Mode
The Double Hit mode is for very soft joint applications. When an electric screwdriver runs down a fastener and the tool clutches off once
the preset torque is achieved there can be some joint relaxation that can occur. The Double Hit mode has the electric screwdriver perform
a second hit to stabilize the torque for joint relaxation.
Joint relaxation is caused by the surface of part(s) embedding or by "soft parts" such as gaskets, plastics or spongy material, which
collapses under the clamping force created in a torque condition. For Hard Joint applications there is no need to use the
Double Hit mode.
Press the "sT" button continuously until the power light turns Red.
The clutch of the electric driver works twice at the set torque under the "Double Hit" mode. The Double Hit will increase the repeatability
accuracy at the target torque by double checking.
