Chapter 3: Using the GX-2012 in Normal Mode
Overview
This chapter explains how to operate the GX-2012 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-2012 is ordered, it is shipped with Bar Hole
Mode disabled so that the instrument only runs in Normal Mode when turned
on.
Start Up, Normal Mode
This section explains how to start up the GX-2012 in Normal Mode, get it
ready for operation, and turn it off.
NOTE: The screens illustrated in this section are for a 4-gas unit that has the
% LEL range for the combustible gas channel. The screens
displayed by your GX-2012 may be slightly different.
