Analog and Digital Value Conversions
It is sometimes useful to do quick conversions between the signal levels and the digital values.
This can be helpful during startup and/or troubleshooting. The following table shows some
formulas to help with the conversions.
For example, if a 10mA signal level is needed, use
the formula to the right to determine the digital
value “D” to be stored in the V-memory location
which is designated to store the data.
