4.6.2 Autoranging Analysis

Set your analysis ranges as in 4.6.1, above. Leave Mode in Auto, or use the arrow buttons to change back to Auto.

When operating in autoranging, if the oxygen concentration in your sample goes ABOVE your HIGHEST range setting, the analyzer will go into the special 25 % cal range.

However, if one of your range settings is below 0-25 % and another is set above 0-25 %, the special 0-25 % Air Cal range will NOT activate as the oxygen level goes through 25 %. Nevertheless, if the oxygen concentration in your sample goes ABOVE your HIGHEST range setting, the analyzer will THEN drop back down into the special 25 % cal range.

Once the oxygen concentration drops back down into your highest range setting, the analyzer will automatically switch back to that range.

CAUTION: While the analyzer is in the Air Cal range, the oxygen reading cannot go over 25 %, even if the oxygen concentration is higher than 25 %.

4.6.3 Fixed Range Analysis

The autoranging mode of the instrument can be overridden, forcing the analyzer DC outputs to stay in a single predetermined range.

To switch from autoranging to fixed range analysis, enter the range function by pressing the Range button on the front panel.

Use the < > arrow keys to move the blinking over AUTO.

Use the ∆∇ arrow keys to switch from AUTO to FX/LO, FX/MED, or FX/HI to set the instrument on the desired fixed range (low, medium, or high).
