Section 4.1
Description
• Instrument indicates the type of spectrometer or analyzer being used. This
parameter cannot be edited in this dialog box; it is edited using the ABB FT-
IR Control Panel applet.
For information on using the Control Panel applet, refer to the FT-IR
Spectrometer Ethernet Interface and External Ethernet for FT-IR
User’s Guide.
• Speed indicates the current acquisition speed in scans per minute (1 scan
includes a forward and a reverse sweep). This parameter cannot be edited.
• Over Sampling indicates whether the instrument is acquiring one sample per
fringe and thus running in Mid IR mode with an upper wavelength limit
around 8000 cm -1 (Over Sampling OFF) or two samples per fringe and
running in Near IR mode with an upper wavelength limit around 16 000 cm -1
(Over Sampling ON). This parameter cannot be edited.
• Detector selects the detector or channel or used to acquire data. The meaning
of this field varies from instrument to instrument:
On an FTPA2000-260 Process FT-IR Spectrometer this field corresponds to
one of the fibre optic channels.
On a Hand Held Diffuse Reflectance Probe only two detectors are defined,
detector 1 corresponds to the diffuse reflectance probe,
detector 2 corresponds to the fibre optic interface.
On a standard FT-IR Spectrometer, detector 1 is the standard detector;
detector 2 corresponds to the auxiliary or the external detector.
• Resolution indicates the current instrument resolution and allows changing
the resolution on instruments that support computer control.
