Calibrating the Eagle
Press and hold the SHIFT/ ▼ button, then press the DISP/ADJ button. The
Calibration menu displays.
NOTE: The following screens illustrate a four-gas Eagle with the data
logging option and are intended as examples only. Your Eagle may
display slightly different screens.
The Eagle’s Calibration menu includes two methods of calibration:
Auto Calibration and Single Calibration.
• Auto Calibration: This method allows you to calibrate all four sensors
simultaneously. It is designed for use with the RKI Four-Gas Calibration
Cylinder and is the quickest and easiest method to calibrate the Eagle.
• 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, or if
you are using single gas calibration cylinders.
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 49.
1. Use the AIR/ ▲ and SHIFT/ ▼ button to place the prompt next to the
AUTO CALIBRATION menu option.
2. Press the POWER/ENTER button to display the Calibration Values
screen.
The gas concentrations displayed in the Calibration Values screen must match
the gas concentrations listed on the Four-Gas Calibration Cylinder. If all
concentrations match, go to step 7. If one or more concentrations do not
match, continue with step 3.
