Note:
The digital monitor uses an internal representation of a 4 – 20 mA interface when
dealing with sensors. Operational sensors have gas concentrations represented
by mA concentrations between 4 and 20 mA. When a digital sensor is in failure
mode, the representation of it’s gas concentration will be set to 0 mA.
