Alarm LEDs
Five sets of red alarm LEDs (light emitting diodes) border the LCD. The
alarm LEDs alert you to gas, low battery, and failure alarms.
Infrared Communications Port
An infrared (IR) communications port is located on the front of the case,
below the POWER/ENTER button. The data transmitted through the port is
in standard IrDA protocol. A computer’s infrared port or an IrDA/USB cable
connected to a USB port can be used to download data saved by the GX-6000
to a computer using the GX-6000 Data Logger Management Program. See
the GX-6000 Data Logger Management Program operator’s manual for data
logging and downloading instructions.
Buzzer
One solid-state electronic buzzer is located inside the case. Holes on the top
front of the case allow the sound to exit the case. The buzzer sounds for gas
alarms, malfunctions, low battery voltage, and as an indicator during use of
the GX-6000’s many display and adjustment options.
Vibrator
A vibrating motor inside the GX-6000 case vibrates for gas alarms, unit
malfunctions, and as an indicator during normal use of the various modes of
the GX-6000.
Printed Circuit Boards (PCBs)
The GX-6000 printed circuit boards analyze, record, control, store, and
display the information collected. The circuit boards are located inside the
case. They are not user serviceable.
Pump
A diaphragm pump inside the GX-6000 draws the sample to the sensors. It
can draw sample from as far as 50 feet from the GX-6000. The pump is not
user serviceable.
CAUTION: Sample hose lengths of more than 50 feet are not recommended
for the GX-6000 because of flow rate reduction.
Flow Chamber
The flow chamber is on the back of the GX-6000 and is held in place by four
phillips screws. The flow chamber seals to the rubber sensor gasket which
seals to the sensor faces inside the GX-6000 and routes flow from the pump
to the sensors and to the exhaust port (on the top of the GX-6000 case).
