* This is the equivalent impedance for the G4AD3 at full scale (20mA).
The equivalent impedance is calculated by using the following formula:
Equivalent impedance = 249 Ohms + 3.3V/0.02A = 414 Ohms
The module has an internal resistance of 249 Ohms in series with a
3.3V zener diode. For more information, see form #426.
** Accuracy figure requires use of gain and offset commands.
