Stand-alone Use
When the averaging function is active it will not only affect the
results displayed on the screen but also the measurement results
which are being printed out from the Display Memory (see
). However, when the averaging function is deactivated – by
pressing AVERAGE again (the LED will switch off) – the original
results (un-shaded) will replace the averaged results on the screen.
Gas:
Gas Setup: there are up to six selections here: A, B, C, D, E and W.
These represent the filters installed in the monitor’s filter carousel.
When setting up a new monitoring task, you can choose freely
between the gases available for each filter (names entered when
calibrating the filters, see sections
and
). Once a gas has
been selected for a filter and the measurement task started, you can
no longer change the gas for this filter in this measurement task.
However, you can still select gases for filters, which have not
previously been used in the measurement task.
Note: only one gas per filter can be selected at a time for
measuring. The W position always represents the water filter
installed in the monitor.
Sample Integration Time: this enables you to make a choice
between speed and accuracy. Generally, the longer the integration
time the more accurate the results. There are several selection
possibilities here:
