Chapter 3: Operation
Overview
This chapter explains how to use the GX-6000 to perform confined space entry
monitoring or general area monitoring in Normal Mode. There are three operational
modes in Normal Mode: Measuring Mode, Display Mode, and Calibration Mode. While
in Normal Mode, the unit is normally operating in Measuring Mode. Display Mode and
Calibration Mode are accessible from Measuring Mode. Display Mode is described in this
chapter. Calibration Mode is described in “Chapter 4: Calibration Mode” on page 69.
The GX-6000 can also operate in Leak Check Mode and Bar Hole Mode. See “Appendix
H: 10.0 eV/Benzene PID Sensor” for operating instructions for Leak Check Mode. See
“Appendix D: Using the GX-6000 in Bar Hole Mode” on page 175 for operating
instructions for Bar Hole Mode.
Start Up
This section explains how to start up the GX-6000, get it ready for operation, and turn it
off.
NOTE:
The screens illustrated in this section are for a standard 4-gas + high range PID
unit. The screens displayed by your GX-6000 may be slightly different.
Turning On the GX-6000
To illustrate certain functions, the following description of the GX-6000 start up sequence
assumes that the following menu items in Maintenance Mode are turned on:
LUNCH
BREAK
,
CAL REMINDER
,
BUMP REMINDER
, and
ID DISPLAY
. If any of these
items are turned off, then the corresponding screens will not appear.
The GX-6000 may be used with a sample hose and probe or with the tapered rubber
nozzle. Determine which configuration works best for your application.
NOTE:
When the sample hose is not being used, its outgassing characteristics may
result in a small buildup of gas to which the PID sensor will respond. If a
sample hose has been sitting unused for a period of time, when that sample hose
is connected to a GX-6000, the PID channel may temporarily show a reading.
The reading will return to a fresh air reading after all of the built up gas has
been drawn out of the sample hose.
1 . Connect the tapered rubber nozzle or the sample hose and probe to the GX-6000’s
quick connect inlet fitting.
2 . Press and briefly hold down the POWER/ENTER button. Release the button when
you hear a beep.
