5.2 Example applications
To take advantage of the full performance of the ELT-400, it is important to
optimize the instrument settings to match the expected characteristics of the
field being investigated. The table below provides assistance for this
important task. It shows typical applications together with the appropriate
instrument settings. Please note, though, that the choice of measurement
range or the lower measurement range limit in particular must be decided
according to the actual measurement situation and the aim of the
measurement.
