Installing your Lambda Spectrometer . 45
NIR Wavelength:
– Select
Manual set
,
Manual set 1 peak
,
Manual set 2 peaks
,
Auto search 1 peak
, or
Auto search 2 peaks
.
–
Manual set
enables you to enter the
offset
and
factor
(without the need to
determine the values in advance).
–
Manual set 1 peak
enables you to change the offset. A well-known peak can be
shifted to an exact wavelength by entering values of
Old Peak 1
and
New
Peak 1
.
–
Manual set 2 peaks
enables you to change the offset and factor by specifying
the old and new values of 2 well-known peaks by entering values of
Old Peak 1
,
New Peak 1
,
Old Peak 2
and
New Peak 2
.
–
Auto search 1 peak
enables you to change the offset. The software performs an
automatic search for the D
2
peak at 1312.2 nm. The measured peak is then
shifted to the exact wavelength.
–
Auto search 2 peaks
enables you to change the offset and factor. The software
performs an automatic search for the D
2
peak at 1312.2 nm and the peak at
0.0 nm. The measured peaks are then shifted to the exact wavelengths.
NOTE:
Auto search 2 peaks
is the default setting.
