For UV-Vis instruments:
• Position B should be empty.
• Use position #1 for the 220 nm stray light standard (SRE 220 or equivalent).
• Use position #2 for the 340 nm stray light standard (SRE 340 or equivalent).
• Use position #3 for the 400 nm stray light standard (SRE 400 or equivalent).
For Vis-only instruments:
• Position B should be empty.
• Use position #1 for the 340 nm stray light standard (SRE 340 or equivalent).
• Use position #2 for the 400 nm stray light standard (SRE 400 or equivalent).
