Fahrenheit

positioning the jumper in the DEG F or DEG C position.

Selecting Data

Locate JP90 on the printed circuit board (See Figure 2-2). Select DISABLE

Scaling

to present data to the PLC as temperature X10 or millivolts X100. Select

ENABLE to scale and present the data as an unsigned integer from

0±32000.
