The algebraic sum of the contacts is obtained. During
normal operation the selector switch must be in this
position.

Zero-setting potentiometer
Three types of zero-setting potentiometers can be supplied:
• 1 turn
• 10 turns with window
• 10 turns with dial
The potentiometer is used for the electric zero-setting of the gauging
system on a master workpiece. Its position must not be changed during the
grinding cycle.
