Calibrating with the Single Calibration method
This section describes calibration using the Single Calibration method.
To calibrate using the Auto Calibration method, see “Calibrating with
the Auto Calibration method” on page 42.
CAUTION:The single calibration method does not have a “FAIL”
notification. Replace sensors that cannot be set to agree with the
calibration source, then recalibrate.
1. Use the AIR/▲ and SHIFT/▼ buttons to place the prompt next to
the SINGLE CALIBRATION menu option.
2. Press the POWER/ENTER button to display the Single Calibration
menu.
3. Use the AIR/▲ or SHIFT/▼ button to place the prompt next to
the channel to calibrate (in this example the combustible gas
channel).
4. Press the POWER/ENTER button. The Single Calibration screen
displays for the channel you selected. The gas reading flashes.
5. Connect the tubing from the regulator to the Eagle’s probe.
NOTE: The combustible gas sensor is a general hydrocarbon sensor
that responds to most flammable vapors and gases; the
response will vary depending upon the substance. For best
results, calibrate the Eagle to the target gas or vapor.
6. If necessary, use the AIR/▲ (increase) and SHIFT/▼ (decrease)
buttons to adjust the reading to match the concentration listed on
the calibration cylinder.
