Analysing Samples

are available the
st symbols will be displayed
next to the current result units. Use the up/down
arrows to change the units of expression as
required. Values are modified automatically.
Results stored in the log will be in the units
selected on screen, changing the chemical species

result and species parameter selected.
6.7 Follow-on Tests
A number of photometric methods have additional
optional methods that can be applied, known as
Follow-on Tests e.g. Phot 008 Total Chlorine follows
Phot 007 Free Chlorine. Follow-on methods are
usually either based on further reagent addition to
the sample just measured for sequential parameters
or used to correct for potential/known interferences.
Follow-on tests are clearly defined in the Section 8
and, if available, are accessed via the
Follow-on
option located at the right hand side of the options.
To access the Follow-on test, highlight Follow-on
and press OK. The next method is automatically
loaded and operated in the usual manner.
NOTE: if no viable result is produced during
the first stage of a sequential test method, the
Follow-on option will be automatically removed.
