Trimming the milliamp (mA) output(s)

Trimming the mA output creates a common measurement range between the transmitter and the device
that receives the mA output. For example, a transmitter might send a 4 mA signal that the receiving
device reports incorrectly as 3.8 mA. If the transmitter output is trimmed correctly, it will send a
signal appropriately compensated to ensure that the receiving device actually indicates a 4 mA signal.
