RKI Instruments SDM-2012 PC Controlled Configuration - Manual (Page 166)

161 • Instrument Function Menu
Option 2 Sub Tab
The Option 2 Tab of the Parameter Tab contains additional instrument parameters
that can be changed.
• HC Pattern: The HC Pattern setting allows the user to select the units for the
combustible gas channel. If you have a standard 4 sensor instrument, this
setting must be set to %LEL ONLY. If you have a standard 4 sensor plus
%volume sensor instrument, you can set the HC Pattern to AUTO or to vol%
ONLY. If set to AUTO, the combustible channel will automatically begin reading
in %volume when the LEL is exceeded. If set to vol% ONLY, the combustible
channel will only read in %volume.
• Backlight Delay: The Backlight Delay setting is how long the backlight stays on
after the last button push. It can be set anywhere from 0 to 255 seconds. The
factory setting is 30 seconds. Use the arrows to the right of the value to make
your selection or highlight the existing value and enter the desired value.
• LB Mode: The LB Mode selection allows you to turn on Leak Check Mode, Bar
Hole Mode, or both. If any of these modes are turned on, you will be prompted to
select an operational mode when you turn the instrument on. The factory setting
is OFF. To update this parameter, select the drop down menu and make your
selection. See the GX-2012 Operator’s Manual or Gas Tracer Operator’s
