Polarity Jumper
Increasing air pressure at the tooling will cause the readout to move upwards when the
polarity jumper is in the (“+”) position. The opposite occurs with the jumper in the (“-”)
position. This switch is used for setup changes between inside and outside diameter
applications. For example, if an air plug is used to measure the inner diameter of a part
then the polarity should be set to ("- ") so that a larger part inside diameter, which causes a
decrease in pressure, causes the readout to increase. If an air ring is used to measure the
outside diameter of a part then the polarity should be set to ("+") so that a larger inside
diameter, which causes a decrease in pressure, causes the readout to increase.
To set the input polarity position jumper "J5", POL, to the ("+") or ("- ") position.
