4. Multiple counter mode
✽
Use this setting when 2 electric screwdrivers with different tightening conditions such
as different torques or bits are to be used in sequence by an operator on a single work
piece.
✽
In the working sequence, when one of the electric screwdrivers is operating, the other
electric screwdriver is prevented from operating.
✽
The total number of work pieces completed can be counted by connecting a commercially
available total counter. Furthermore, if they are connected using the daisy chain method,
the number of electric screwdrivers can be further increased.
●
When using 2 devices, the first is designated “A” and the second “B”.
