Metrohm NIRS XDS MultiVial Analyzer - Manual (Page 44)

42 ▪▪▪▪▪▪▪
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, and are done rapidly. 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.
Verify that the box marked “Reference Standardization” is checked. If it is not, the user should
return to Configure, Options and select “Reference Standardization” on that menu before
establishing a DCM.
Click “OK” to exit the dialog box. The DCM information will be saved.
Next, select this DCM from the selection box.
Click “OK” to connect to the instrument.
Once connected, verify that the amber
“Communication” LED is lit on the instrument
Vision will connect with the instrument, and may
display a message that a reference is being
acquired to determine instrument stabilization.
If the instrument lamp has been on for some
time, this message will only be displayed for a
few scans. Otherwise, it may take some time for
the instrument to come to full internal operating
temperature.
