Calibration In Progress (2

nd

Point)

Note

. The test gas used for this stage of the procedure is always test

gas 2.

Test gas detection is monitored and, if no test gas is detected, the
calibration fails. Otherwise the test gas valve is opened and the
procedure continues (not applicable if the

Test Gas Type

is

Process

Air

– see page

).

Test Gas Response Time monitored – if no response to the
application of the test gas is detected, the test gas valve is closed and
the calibration fails.

At this point the calibration procedure remains idle while the test gas
delay timer runs (AutoCal only).

Oxygen value is monitored for stability, if the stability criteria are not
met, the test gas valve is closed and the calibration fails.

Once the stability criteria have been met a cell impedance check is
performed and the test gas valve is closed.

Once the stability criteria have been met, a cell impedance check is
performed, the test gas valve is closed and, finally, the process values
are collated with those retained following the 1

st

-point calibration

stage and the calibration coefficients (

Offset

and

) are

re-calculated.

If either or both of the new coefficients are outside the permitted limits
(defined by

Offset Limit

and

– see page

calibration fails and a

calibration entry is added to the
