5 OUTPUT CONVERSION FACTOR
The following table describes how program data values are scaled to real-world analog voltage outputs by
the module. Given a desired output current, the data value is converted by using the conversion factor
from the table. The following formula is used: Data = Output Current (mA) / Conversion Factor
Example: The user selects a current range of +20 mA:
1) The desired output current is 12 mA.
2) Using the table, the conversion factor for the current range of +20 mA is 0.000625.
3) To determine the data value, the formula is used:
Data = Output Current (mA) / Conversion Factor
19200 = 12 mA / 0.000625
