3.7 Analogue Output
The analogue output provides a means of indicating to external equipment
(e.g. data loggers, remote displays) the gas levels currently being detected by
the system. The output is that of a Current Source (4-20mA), where 4mA
represents zero gas and 20mA represents gas at the sensor FSD.
