To get access to the entry field, the right to "Edit Expert Values" need to be
assigned to you in the Security Designer under Security Policies. For
further details read more under "
Extended Wavenumber Range ".
Lower Wavenumber
Limit This parameter is for information only.
Lowest wavenumber of the spectra.
Datapoint Interval This parameter is for information only.
Intervall between two datapoints in wavenumbers.
External Reference
Comparison If checked, the new measured external reference spectrum will be compared to
the last measured spectrum.
Maximum allowed
deviation of the reference
spectra This parameter defines the maximum allowed deviation in percentage.
For the calculation of the deviation the following formula is used:
Ra = Max(Abs(R1/G1 - R2/G2) / Max(Abs(R1/G1))
R1 = Previously accepted external reference spectrum vector
R2 = Newly measured external reference spectrum vector
G1 = Gain factor of R1
G2 = Gain factor of R2
Value range: 1...100
Position of
Standardwheel for
sample measurement Use with care!
The standard wheel contains 5 grey standards, a internal wavenumber
standard and an empty position. Define, which position should be in
the light beam for sample measurement:
0 = empty (Default)
1 = filter 1 (ca. 2%)
2 = filter 2 (ca. 10%)
3 = filter 3 (ca. 29%)
4 = filter 4 (ca. 64%)
5 = filter 5 (ca. 92%)
6 = PMMA
7 = Do not use this setting (causes error)
Position of
Standardwheel for
reference
measurement Use with care!
The standard wheel contains 5 grey standards, a internal wavenumber
standard and an empty position. Define, which position should be in
the light beam for reference measurement:
0 = empty (Default)
Suitability Test Mode Define the SST Test procedure:
Interval = Test will be performed after the below defined time period is
exhausted (default)
Disabled = No SST Test will be performed automatically.
