4.7 The Analyze Function
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
Analyze
function. Alternatively, you can press the
Analyze
button
at any time to return to analyzing your sample.
4.8 Signal Output
The standard Model 3010MA Paramagnetic Oxygen Purity Analyzer
is equipped with two 0–1 V dc analog output terminals accessible on the
back panel (one concentration and one range ID). The standard model also
includes one isolated 4–20 mA dc current outputs for the oxygen
concentration.
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 98–100% O
2
, then the output would be:
