The Gas Analyzer - ADInstruments

Power Indicator
The Power indicator is located on the left hand side of the front panel and
will glow blue when the power is connected properly. If the light does not
illuminate when the Gas Analyzer is switched on then the power cable may
not be connected properly or a fuse may have blown. If the internal fuses
are suspected of having blown, the unit should be returned to your local
ADInstruments representative.
Status Indicator
The Status indicator glows green when the Gas Analyzer is connected to a
PowerLab and has been recognized by LabChart.
Pump On Indicator and Switch
The pump is activated using the switch. The indicator glows yellow, and the
internal pump may be heard, when it is running.
Gas Sample Inlet
A sample inlet port is provided on the front panel. The inlet port is directly
connected to the internal gas transducers of the Gas Analyzer. A sample flows
through this port to be analyzed. Note that the hydrophobic filter, supplied
with every unit, must be used at all times
Flow Control
A single-turn knob on the front panel controls the sampling flow rate to suit
different applications.
