flags
This reports 8 hexadecimal digits (or flags) that represent status of the
ozonator, PMT, pressure and temperature compensation status, gas units,
gas mode, and alarms. To decode the flags, each hexadecimal digit is
converted to binary as shown in the Figure B-1. It is the binary digits that
define the status of each parameter. In the example below, the instrument is
reporting that the ozonator and PMT are both on, that the instrument is in
the span gas mode, that at least one of the alarm temperature is activated,
and that the NO
2
high concentration alarm is activated.
