NOTE: The following screens illustrate a three-gas Gas Tracer with a
%LEL and a %volume combustible 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 211 for
instructions.
Calibrating with the Auto Calibration Method
This section describes calibration using the auto calibration method.
To calibrate using the single calibration method, see “Calibrating with
the Single Calibration Method” on page 201.
NOTE: If the combustible gas channels are calibrated to a gas other
than methane, use an appropriate multigas cylinder to fill the
gas bag or use single calibration to calibrate the combustible
channels.
1. You may only calibrate either the standard 3 sensors or the
%volume combustible gas sensor at a time. Once you are finished,
