RKI Instruments SDM-2012 Standalone Configuration - Manual (Page 82)

77 • Calibrating a Gas Tracer
8. Press and hold the POWER ENTER button on the Gas Tracer until you hear a
beep, then release it. The Gas Tracer will begin its power up sequence (see
exceptions below in step 9). If a successful connection between the instrument
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. All Gas Tracers will scroll through the
%LEL and ppm auto calibration values. The %volume auto calibration value
will only appear if you have a %volume combustible gas sensor installed. If the
charge LED was amber, it will begin to blink green.
NOTE: The screen above applies to a standard Gas Tracer with a %volume
combustible gas sensor installed. All screens in this section will be
shown for a standard Gas Tracer as well as a standard Gas Tracer with
a %volume combustible gas sensor installed.
9. There are three exceptions to the sequence described above in step 6 above.
See 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 Gas Tracer. If you do
not press the POWER ENTER button for 20 seconds, the instrument will
automatically continue its warm up sequence in Normal Mode.
