4 CALIBRATION
In order to acquire stable, accurate data, perform calibration when starting measurement and
at regular intervals.
There are two types of calibration, the auto calibration (AIC) and the manual calibration.
Auto calibration (AIC)
The AIC sequence is executed at the specified time intervals or with the externally inputted
command to perform the zero calibration and span calibration automatically.
Manual calibration
This calibration is performed manually at an arbitrary timing.
There are two methods available for the manual calibration; one uses the calibration gas line,
and the other supplies the calibration gas to the measured gas line.
4.1 Calibration-related Screens
This section describes the screens used for the automatic calibration and manual calibration.
4.1.1 CAL. screen
This is the basic screen for calibration.
To display the CAL. screen, press the [CAL.] key on the MEAS. screen (Fig. 5 on page 7).

1: MODE
The selected measurement line is displayed.
Press the displayed MODE setting, and the MODE screen will be displayed (see “4.1.2 MODE
screen” (page 12)).
