Example
Auto calibration is made in the following rules according to the setting.
1. Zero calibration at once of CHs (components) which were set to "enable".
2. The span of CHs (components) which were set to "enable" is calibrated in the
ascending order of CH number.
Example 1. In case all of CH1: CO2, CH2: CO, CH3: O2, were set to "enable".
Zero calibration (at once) of CH1 to CH3 n span calibration of CH1 (CO2) n
span calibration of CH2 (CO) n span calibration of CH3 (O2)
Example 2. In case, out of CH1: CO2, CH2: CO and CH3: O2, CH1 ( CO2) was set to "enable",
CH2 (CO) was set to "enable" an CH3 (O2) was set to "disable".
Zero calibration (at once) of CH1 and 2 n span calibration of CH1 (CO2) n
span calibration of CH2 (CO)
CAUTION
The components which were set to "enable" is calibrated to zero at once at the time of auto calibration
regardless of setting in "6.2.2 Setting of manual zero calibration".
