3.8.2 Measurement Aperture
YS series spectrophotometer features with 8mm, 4mm, 1*3 mm aperture.
Different model has different aperture. When the area of measured
sample is large and uniformity, it is recommended to use 8mm aperture,
while it is small, recommenced 4mm aperture.
Switch aperture is required to follow the three steps.
Step 1: As shown in Figure 47, counterclockwise rotates the measurement
aperture, and take off it, then install the new aperture clockwise. When
hearing a voice, it shows ok.
Step 2: As shown in Figure 1, if it is
Φ4mm aperture, it is required to
switch to SAV; if it is
Φ8mm aperture, switch to MAV.
Step 3: Switch the default system measurement aperture to correspond
with the actual measurement aperture. As shown in Figure 44, the current
measurement aperture is Φ 8mm. After switching the measurement
aperture, you have to re-calibrate the instrument according to part 2.2.
Note: Please confirm the system measurement aperture should be the
same with the actual aperture. If it is Φ4mm aperture, switch to SAV; if
Φ8mm aperture, switch to MAV, or it could cause wrong test result.
