2
S and
calculating concentrations.
6.2.1. Test Functions
A series of test functions is available at the front panel while the analyzer is in SAMPLE mode.
These parameters provide information about the present operating status of the instrument and
are useful during troubleshooting (Section 11.1.2 ). They can also be recorded in one of the iDAS
channels (Section 6.11) for data analysis. To view the test functions, press one of the
