then directly indicated by the notches in the segments. Increments on the scale only serve to provide a more accurate
division between the maximum and minimum torque levels, and thus to enable a more precise set-up of the tripping torque
outside the manufacturing plant if no loading bench is available. Segment 23 is intended for “closing” direction, segment 24
for
“opening”
direction.
