85 • Calibrating the GX-2003 GX-2003 Operator’s Manual

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.

Allow the GX-2003 to sample gas for one minute.
