RKI Instruments SDM-2012 Standalone Configuration - Manual (Page 55)

Calibrating a GX-2012 • 50
and the SDM-2012 occurs, the home screen will appear on the instrument
display at the end of the startup sequence. The heart symbol will be flashing
and the combustible channel will scroll through the auto calibration values for
all installed combustible gas sensors. If you have a standard 4-channel GX-
2012, only the auto calibration value for the %LEL channel will be displayed. If
the charge LED was amber, it will begin to blink green.
NOTE: The screen above applies to a standard 4-gas GX-2012 with a
%volume combustible gas sensor installed. All screens in this section
will be shown for a standard 4-gas GX-2012 as well as a standard 4-
gas GX-2012 with a %volume combustible gas sensor installed.
9. There are three exceptions to the sequence described above in step 6 above.
See the GX-2012 Operator’s Manual or the Gas Tracer Operator’s Manual for
a description of the L./B. MODE, CL RMNDR, and CL EXPRD instrument
parameters.
• When L./B. MODE is set to anything but OFF, the Normal Mode Select
Screen will appear.
Press and release the POWER ENTER button on the GX-2012. If you do
not press the POWER ENTER button for 20 seconds, the instrument will
automatically continue its warm up sequence in Normal Mode.
