With a very small bias current multiplied by this high input
impedance, the voltage produced is out of the common-mode input
range of the instrumentation amplifier.
An external resistor must be provided to return this bias current to
the analog common of the data acquisition board. This resistor is
typically in the order of 1 kΩ to 100 kΩ from the input low side to
analog common. Alternatively, the external common can be returned
through a 10 Ω to 100 kΩ resistor to analog common (it cannot be 0 Ω
due to ground currents).
