Span
Calibration
Caution
Indicates that the
coefficient revised at the
span calibration starts
reaching the outside of
specified range.
Confirm the gas type
of calibration gas
cylinder.
Confirm that there is
enough residual
pressure of
calibration gas.
By the flowmeter of
analyzer front panel,
confirm that there is
the specified flow.
If the wrong gas type is
selected, perform the
calibration again with the
correct gas type.
If the residual pressure of
calibration gas is within 1
MPa, replace it into a new
cylinder and perform the
calibration again.
Adjust the flow so that it is
within the specified level,
and perform the calibration
again.
If the situation is not
