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” above.
CAUTION: The single calibration method does not have a “FAIL”
notification. If a sensor cannot be set to agree with the
calibration source, see the “Troubleshooting” section of the
Operator’s Manual.
1. While in the calibration menu, use the ▲AIR or (SHIFT) ▼ button
to place the prompt next to the SINGLE CALIBRATION menu
option.
2. Press and release the POWER/ENTER button to display the single
calibration menu.
NOTE: To display the CO sensor, use the (SHIFT)▼button to move
the cursor to the bottom of the screen and then press it again
to advance to the next screen.
3. Use the ▲AIR or (SHIFT)▼ button to place the cursor next to the
sensor you want to calibrate (in this example the combustible gas
%LEL sensor).
4. Press and release the POWER/ENTER button. The single
calibration screen displays for the sensor you selected. The gas
reading flashes.
5. Connect the tubing from the gas bag to the rigid tube on the probe.
