Polarity
The polarity of the input determines whether the input reads positive or negative as the
probe tip is depressed. The bargraph will rise when the tip of the probe is pressed toward
the body of the probe in the (+) setting. The polarity of input A and input B can be set
independently. For example, if a gaging fixture uses two LVDTs to measure an outside
diameter, then the polarity of both probes should be set to ("+") so that for larger part
outside diameters the readout would show a larger size.
To set input polarity position the input polarity switches on the circuit board to ("+") or
("- ") as shown in figure 4.7 or set jumpers J12 and J13 as shown in figure 4.7a. Figure
4.7a shows the current version of the jumper settings, while figure 4.7 shows the obsolete
original version.
