For example, if Polarity is set to Bipolar, then setting the Monitor Out –10 V parameter
to 0 K and the Monitor Out +10 V parameter to 100 K will cause the analog output to
correspond to the input temperature as shown in FIGURE 5-3. In this case if the actual
reading was 50 K, then the output would be at 0 V (middle of the scale).
If we set the Polarity parameter to Unipolar, the output would be as shown in
FIGURE 5-4. In this case if the actual reading was 50 K, the analog output would be
+5 V (middle of the scale).
