Lesson 3: Measuring in a Transmittance Mode
This lesson is appropriate only if you are using an instrument capable of measuring in transmission. If
you are using a ColorQuest XE, ColorQuest XT, ColorQuest II Sphere, UltraScan XE, UltraScan PRO,
or UltraScan VIS, proceed with this lesson. If you are using a ColorFlex, ColorQuest 45/0 LAV,
LabScan XE, MiniScan XE Plus, or MiniScan EZ, do not attempt this lesson. Your instrument should
already be attached to the computer and installed in EasyMatch QC before performing this lesson.
Most transmission measurements are made using the TTRAN (total transmittance) mode. The steps
required for performing this type of measurement are described below.
1. Choose Set Modes from the Sensor menu. The following screen will appear.
2. Highlight each of the existing modes in turn and examine the parameters shown on the right side of
the screen until you find the standardization mode desired (TTRAN for the largest area view
available with the UV Filter Position Nominal). If such a mode doesn’t exist, create it using the
Add
Mode button.
3. With the desired mode selected (highlighted), click Standardize . The following prompt will appear.
4. Place the black card inside the transmission compartment, flat against the hole in the sphere. Close
the transmission compartment door as much as possible and click Next .
