Infrared Gas Analyzer Operation

This brings up the Cal. Settings ZERO Cal. screen where you can set whether all components or individually selected components are zeroed during a manual zero calibration. The choices are:

•at once—these components will be zeroed simultaneously during a manual zero.

•each—these components will be zeroed individually during a manual zero.

To change the manual zero setting:

1.In the “Cal. Settings ZERO Cal.” screen, point the cursor to the channel you want to set by using the UP or DOWN key. Press the ENT key.

2.Select “at once” or “each” by pressing the UP or DOWN key to toggle between the two options. Press the ENT key when the desired option is displayed.

To close the Cal. Settings ZERO Cal. screen or cancel this mode midway, press the ESC key. The previous screen will return.

Example:

The options “each” or “at once” can be determined for each channel.

•When the setting is “each”, select the channel on the manual zero calibration screen (see Section 3.7) and perform a zero calibration. Only that component is zeroed.

•When the setting is “at once”, performing a manual calibration (see Section 3.7) will zero calibrate all components tagged “at once”. You will notice on the manual
