Metrohm NIRS XDS Transmission OptiProbe Analyzer - Manual (Page 37)

▪▪▪▪▪▪▪ 35
A Data Collection Method (DCM) must be
established to communicate with the
instrument.
There are no Data Collection Methods available
upon initial connection. Click on “New”.
The instrument “self-identifies” as an XDS system. The DCM will self-select as an OptiProbe Module.
Select the proper probe type, Transmission Pair. The user should enter a logical name for the DCM.
Use 32 scans for “Sample” and 32 scans for “Reference.” The instrument scans on each forward
swing and each backward swing of the grating, unlike previous Metrohm instruments. Thus, 32 scans
are accomplished on only 16 grating cycles. This is very rapid. Click “OK” when finished.
The user will hear a slight ticking sound from the internal order sorter whenever the lamp is on. This
is normal, and has no effect on component life. The parts are kept in motion to reduce “wait time”
before instrument stabilization.
