Figure 1-1. The Standard Bulk Measurement Screen
When you end a reading, the Measurement screen will be replaced by the
Result screen. These screens displays the reading grouped as follows:
At the top, elements detected in the sample, and, underneath this, elements
that were below the detection limit.
Use the 4 way touch pad to scroll through the elements.
For an element to be detected by the analyzer in a given sample, the
measured concentration of the sample must be at least three times the
standard deviation of the measurement. This detection limit will depend on
the composition of the sample.
Precision
The measurement precision for each element displayed appears to the right
of the measured concentration, under the heading "+-". The precision of
each measurement is two times the standard deviation (sigma).
