4.7 The Analyze Function
When the Analyze function is active, the 3010PAC is monitoring the
sample gas currently flowing in the Analysis Unit cell block. All undefeated
alarms are ready to activate should their respective setpoints be crossed.
Press the Analyze button to put the analyzer in the Analyze mode.
Normally, all of the functions automatically switch back to the Analyze
function when they have completed their assigned operations. Pressing the
Escape button in many cases also switches the analyzer back to the Ana-
lyze function. Alternatively, you can press the Analyze button at any time
to return to analyzing your sample.
4.8 Signal Output
The standard Model 3010PAC Oxygen Analyzer are equipped with
two 0-1 V dc analog output terminals accessible on the back panel (one
concentration and one range ID). Two isolated 4-20 mA dc current outputs
(one concentration and one range ID), in addition to the voltage outputs, are
optional.
See Rear Panel in chapter 3, Installation, for illustration.
The signal output for concentration is linear over the currently selected
analysis range. For example, if the analyzer is set on range that was defined
as 0–10 % O
2
, then the output would be:
