For Vista Essentials 1.04.0056 and above:
Through Custom Indices, users can create modified-pathlength indices and add transmittance data into indices list.
Indices available for pathlength modification are APHA, ASBC, ASTM D1500, Chinese Acid Wash Color, EBC, EP, FAC, Gardner, Iodine, JP, Saybolt, USP. After these custom indices are created, they are shown in the Bias Configuration list so that user modify the bias and gains.
Any transmittance/absorbance data from 400nm to 700nm can be added into indices list.
Note: Absorbance is available in Vista Essentials Rev 1.06.0079 and above.
- The configured pathlength can be any number between 0-100 with maximum one decimal.
- Due to the implementation of custom indices feature, most indices names have been changed compared to the names in Vista Essentials 1.03.0045. If any old index name is found in different format to the new, index will not be calculated. In such case, please go to COLOR SCALES > INDICES and APPLY to update the list of indices.
- The custom indices can only be the ones that not listed in the default indices list. If the user tries to create APHA 10mm in custom indices dialog, it will not work. This index already exists in the default indices list.
- Scale factors of LOVIBOND®/AOCS/ICUMSA 420/ICUMSA 560 can be adjusted in custom indices dialog. LOVIBOND®/AOCS cell pathlength, instead of only 5 pathlength options in dropdown list, can be entered with any number between 0-100 with maximum one decimal.
For ICUMSA 420 and ICUMSA 560, the density (g/ml) and weight%(g/g) need to be configured for accurate ICUMSA calculation. Density (g/ml) should be from 0.5-2. Weight% (g/g) should be from 1-100.
