5.
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.

Haze Measurements
Measurement and Calibration Notes
•
To obtain a true haze measurement requires a haze meter (ASTM D1003). It is possible,
however, to use a sphere geometry spectrophotometer capable of transmission
measurements to obtain an index, known as correlated haze, with good correlation to a
haze meter.
•
The sample to be measured is placed against the sphere.
•
To calibrate use the 25 mm aperture plate (with white reflective ring), transmission white
plaque and black trap positioned at the reflectance port.
•
Before you can take a Haze measurement you need to calibrate for the haze
measurement first, unless you are already in Haze Measurement mode using a current
haze calibration.
Procedure:
1.
Mount the 25 mm aperture plate with the white ring at the measurement port as previously
explained.
2.
Select “Haze” as the measurement type within your software.
3.
A haze calibration is automatically launched. Follow the prompts from the software regarding
calibration.
4.
Once the haze calibration is complete you can begin to take haze measurements.
5.
Load your sample in the transmission sample holder at the sphere within the transmission
compartment.
6.
Select “Measure Standard”, “Measure Trial”, or press the appropriate measure button on the
instrument.
7.
If you later change the measurement mode to another measurement type than Haze you
may be prompted to calibrate the instrument.
