MEASURING
You should refer to the documentation or online help for the software application that you are
using with your instrument. All applications that use the instrument must be running during
measurements.
Reflectance Measurements
To take a measurement using your spectrophotometer, follow these steps to ensure an accurate
reading.
1.
Ensure the desired aperture plate is installed.
2.
Edit the current configuration or load appropriate configuration from the application.
3.
Calibrate for the current configuration if needed.
4.
Prepare your sample for measurement.
5.
Open the sample holder on the spectrophotometer to the fully open position. Position the
sample at the view port and slowly close the sample holder. The sample holder is dampened
to prevent the holder from closing with too much force and possibly damaging the sample.
6.
Use the computer screen or the drop down door to view the sample and adjust the sample
measurement targeting area.
Caution: Do not look directly into the measurement optics when the instrument is on.
7.
Trigger the measurement using one of the following methods:
a.
Select "Measure Standard" or "Measure Trial" from your software. Follow the software
instructions for loading the sample at the view port.
OR
b.
Press the Standard or Trial button on the instrument front panel.
8.
The measurement is taken. The data is displayed in your application. Follow the instructions
for saving the data in the software.
Note:
When measuring large or oddly-shaped samples you can open the sample holder completely or
remove the sample holder if necessary. The sample is then held securely against the view port.
It is also recommended that you remove the four outer hole plugs from the front of the
instrument to ensure that large samples remain flat during measurements.
When holding a sample for measurement yourself, remember to keep the sample perfectly
still. Also, the sample surface should be able to rest completely flat against the aperture plate,
preventing any light from entering the view port.
