• Internal Wavelength Performance (wavelength positions on non-traceable, internal reference
materials.)
• Internal Wavelength Precision (Repeatability)
• NIR Gain
• Visible Gain
The test is initiated as follows:
Select Performance Test from the
Diagnostics menu. Click on Run
Performance Test.
Verify that the OptiProbe is inserted into the Reference
