3. The display values for analog inputs are scaled from 0 to 25,000 counts; it is also linear for RTD
input.
4. Use the
▼
or
▲
keys to select a display value from 0 to 10 and to check the linearity of output
circuit at 0%, 10%, 90% and 100% of full scale value.
5. If the values do not correspond with the values in the Calibration Parameters Summary Table
below, use the
▼
or

keys to correct the value displayed.
6. When all the appropriate values are correct, set the dip switches to operating mode.
