Press
Escape
to re-enter the
Analyze
mode using the fixed range.
NOTE:When performing analysis on a fixed range, if the oxygen
concentration rises above the upper limit (or default value) as
established by the operator for that particular range, the
output saturates at 1 V dc (or 20 mA). However, the digital
readout and the RS-232 output continue to read the true value
of the oxygen concentration regardless of the analog output
range.
4.7 The Analyze Function
When the Analyze function is active, the 3010TAC 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.
