is recommended to use the Ø 8mm orifice plate, and when the measured surface
area of the sample is small, it is recommended to use the Ø 4mm or Ø 1*3 orifice
plate. Switching the orifice plate (Ø8mm/Ø4mm/Ø1x3) must be done in three
steps:
Step 1:
Insert the orifice plate, turn the orifice plate anti-clockwise and remove the
original orifice plate. Align the orifice plate to be installed with the mounting hole
of the integrating sphere and turn it clockwise. If a "click" is heard, this means
that the orifice plate is well aligned with the buckle position of the integrating
sphere, i.e. the orifice plate to be installed is in place.
Step 2:
Switch the position of the optical lens. If the mounted Ø8mm aperture is used to
measure the aperture, you must set the aperture switch to the MAV position; if it
is a Ø4mm measuring aperture, set the aperture switch to the SAV position; if
the mounted Ø1*3 aperture is used, you must set the aperture switch to the SAV
position.
Step 3:
Switch the aperture setting in the device software and set the aperture manually.
Corresponding Ø8mm l Ø4mm l Ø3 orifice plate.
Note: The size of the measuring aperture, the position of the optical lens and the
aperture setting of the software must match to ensure accurate test results. Ø1x3
aperture, the corresponding position of the optical lens is SAV, and the software
indicates that it is 1*3; Ø4mm diameter, the corresponding position of the optical
lens is SAV, and the software indicates Ø4mm; Ø8mm aperture, the
corresponding position of the optical lens is MAV, and the software indicates Ø8;
There is a corresponding indicator in the status bar of the test interface.
Note: After switching the measuring aperture, the black/white calibration
must be carried out again before a new data test can be performed.
