Transmitter Startup
When the transmitter is
powered on, it displays a
sequence of information
screens. The screens are shown
for a few seconds each.
The first screen identifies the
transmitter and the connected
measurement modules,
and shows if the transmitter
is operating normally
(status OK) or if there is an error
(status ERROR).
The following screen(s) show
the configuration of the analog
output channels and pressure
compensation setting for CO
2
measurement (GMW models).

After the startup screens the
transmitter shows the
measurement screen. It shows
the measured parameters and
currently active indicators.
