Chapter 3: Using the GX-2003 in Normal Mode
Overview
This chapter explains how to operate the GX-2003 in Normal Mode.
Normal Mode is used to perform confined space entry monitoring or
general area monitoring. While in Normal Mode, Display Mode and
Calibration Mode are accessible.
If a standard version of the GX-2003 is ordered, it is shipped with Bar
Hole Mode and Leak Check Mode disabled so that the instrument
only runs in Normal Mode when turned on.

This section explains how to start up the GX-2003 in Normal Mode,
get it ready for operation, and turn it off

displayed by your GX-2003 may be slightly different.
