Preset Calibration
Oxygen Calibration Sequence
Cell Zero mV
The upper display shows the millivolt offset of the oxygen probe from the last
successful calibration.
Span % of Theory
A value between 90 and 110% should be displayed. If the value is outside these
limits then the oxygen probe must be checked.
Calibration User Code
Enter the required code number between 00000 and 19999, to gain access to
the calibration page. If an incorrect value is entered, access to the calibration
page is inhibited.
Preset Calibration
Select the preset calibration sequence.
Adjust Cell Zero
[0 to
±
10mV]
The upper display shows the cell output (in mV) corresponding to a reading of
20.95 %O
2
. Adjust the reading to correspond with the probe.
Span Theory
Select
YES
if the 'Span % of Theory' parameter is to be reset to 100%. Select
