Data from other instruments can be used as the baseline or
Source
values for the Custom Spectral Calibration.
The following criteria must be met:
A. The
Source
must have the same starting and ending wavelength points, and the same wavelength
(data) increment.
B. The file must have a
.TXT
file extension.
C. The file must have the following file format:
Line 1
– Title (Alpha / Numeric characters only – no spaces)
Line 2
– 380 (Starting Wavelength)
Line 3
– 780 (for PR-730/740/788) or 1080 (for PR-735/745) – Ending Wavelength
Line 4
– 1 (for PR-730/740/788) or 2 (for PR-735/745) – Wavelength (Data) Increment (in
nanometers)
Line 5 to Line N
– Spectral values

Target
instrument.
3.
Make sure
Custom Spectral Correction
is
Disabled
and that
