Slow
Recovery
Diag.
Warns if the probe's recovery rate is slower than
expected after a calibration or accuracy check is
measured.
Note
. The recovery rate is measured only if the
difference between the test gas and process gas values
is > 10 % of the oxygen range.

Impedance
Diag.
Warns if the cell's impedance goes above a preset limit
(a high impedance can indicate a faulty or ageing cell).

Measure
Impedance
With a stable output from the cell, a cell impedance
check can be performed:
Note
. The cell impedance cannot be calculated if the cell
output is less than 20 mV (test gas value greater than
approximately 8 % O
