RKI Instruments Gas Tracer - Manual (Page 72)

64 • Calibration Mode Gas Tracer Operator’s Manual
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 three-gas Gas Tracer with
both a %LEL and %volume combustible gas sensor as
examples only. Your Gas Tracer may display slightly different
screens.
The Gas Tracer’s calibration menu includes two methods of
calibration:
• Auto Calibration: This method allows you to calibrate the
combustible gas (%LEL sensor only), OXY, and CO sensors
simultaneously. It is designed for use with the RKI 3-gas calibration
cylinder and is the quickest and easiest method to calibrate the Gas
Tracer. If installed, you may also calibrate the %volume sensor
separately from the standard three.
• 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 3-gas calibration cylinder.
NOTE: These methods only apply to the standard 3 sensors and the
vol% sensor (if installed). The PPM sensor must be calibrated
independently using PPM CAL. See “Calibrating and Bump
Testing the PPM Combustible Sensor” on page 76 for
instructions.
