Calibration range setting
Touch the Calibration Range item to select the range (Range 1 or Range 2) to be used for
calibration from the selection dialog that appears.
During calibration, it automatically switches to this set range and returns to the original range at
the end of calibration.
The range identification contact is linked to the range at the time of switching, but if the hold
setting is set to "ON", the contact state is held in the state before calibration
l
Set span gas concentration
Set the span gas concentration in the keyboard dialog that appears by touching the Span Gas
Concentration item.
CAUTION
• Enter the setpoint corresponding to the calibration range. If an external oxygen analyzer
is used for the oxygen analyzer, set the external oxygen analyzer itself according to the
instructions for use of the external oxygen analyzer
• If an external oxygen meter is subject to automatic validation, refer to the span gas
concentration set in the external oxygen meter and set the value. Used as a judgment value
during validation
• Even if the unit display of Ch (component) is "mg/m
3
" or "g/m
3
", the unit for span gas
concentration setting is set in "ppm".

Manual Zero Calibration Setting
Sets whether manual zero calibration is performed simultaneously with other measurement
components or individually. From the selection dialog that appears by touching the Manual Zero
Calibration item, select the action (individual or simultaneous) to be taken during manual zero
calibration.
• Zero calibration is performed for each Ch (component) when "Individual" is selected.
• When set to "Simultaneous", all Ch (components) set to "Simultaneous" are zero-calibrated
at the same time.
* Set "Simultaneous" if a standard gas cylinder or atmosphere is used as zero gas.
