GX-2012 Operator’s Manual Calibration Mode • 59
To return to normal operation, press and release the RESET SILENCE
button. You may then try to reenter Calibration Mode.
MAINTENANCE will appear along the top of the screen once you have
entered Calibration Mode. The first item in the calibration menu, AIR CAL,
displays.
NOTE: The following screens illustrate a four-gas GX-2012 with both a
%LEL and a %volume combustible gas sensor as examples only.
Your GX-2012 may display slightly different screens.
The GX-2012’s calibration menu includes two methods of calibration:
auto calibration and single calibration.
• Auto Calibration: This method allows you to calibrate the combustible
gas (%LEL sensor only), OXY, H
2
S, and CO sensors simultaneously. It is
designed for use with the RKI 4-gas calibration cylinder and is the
quickest and easiest method to calibrate the
GX-2012. If installed, you may also calibrate the %volume sensor
separately from the standard four.
• Single Calibration: This method allows you to calibrate one sensor at a
time. Use this method if you are only calibrating one or two sensors, if
you are calibrating only the %volume combustible sensor, or if you are
not using the RKI 4-gas calibration cylinder.
