6.8.2 Manual span calibration
It is used to perform a span point adjustment. Supply calibration gas with concentration set to the span
value to perform the span calibration. For the span calibration gas for the NO
measurement, use the standard gas with a concentration of 90 to 100% of its measuring range value.
For the span calibration gas for the O
ment, use the standard gas with a concentration
of 90 to 100% of its measuring range value
when measuring with the built-in O
