6.
Pull the clamp back and position the sample between the clamp and stop. You may want to
temporarily tighten the carriage base thumb screw to hold the clamp in place while
positioning the sample. Slowly release the sample clamp/carriage base to secure the sample.
7.
Once properly position, tighten the thumb screws and close the transmission cover.
8.
Initiate the measurement by selecting “Measure Standard" or "Measure Trial" from your
software application, or press the Standard or Trial button on the front panel.
9.
The measurement is taken. The data is displayed in your application.
10.
Follow the instructions for saving the data in the application.
Direct Transmission Measurement
Direct measurements are taken with the sample positioned towards the lens in the back of the
instrument. Direct Transmission is appropriate for measuring transparent samples which exhibit
no scattering of the light. This would generally be samples colored with dyes rather than
pigments. When measuring with this method the diffuse light is collimated, this means that the
light rays are travelling in a parallel fashion as they pass through the sample.
Note:
When performing Direct Transmission measurements, only the 25mm clamp, stop, and
aperture plate (with white reflective ring) should be used.
1.
Mount the 25 mm aperture plate (with white reflective ring) to the measurement port at the
front of the instrument.
2.
Position the transmission white plaque on the sample holder as previously explained in the
calibration section.
3.
Open the transmission cover by lifting up on the locking pin while sliding the cover to the
back.
