10. ALWAYS KEEP THE FILTER TAPE IN POSITION ACROSS THE ANALYTICAL AREA.
When prompted, insert ND element No. 0 (zero) ON TOP OF the filter tape. DO NOT TOUCH
the glass – hold it by the metal studs. Insert it with the "V" notch facing forwards.
11. Press "OK" when inserted. Watch the screen, and remove the filter disk when prompted.
12. Repeat the same procedure when prompted for ND elements 1, 2 and 3.
13. The test is completed after ND element No. 3 is removed.
14. The instrument will generate a report which shows the instrument serial number, date and
time of the test; and the results of the test. This report is also saved internally and is available
for future download.
15. Correct operation is shown by report values on both spots (Spot1 and Spot2) within +/-
10% of 1.000 : i.e., between 0.9 and 1.1 for all seven wavelengths (Ch1 to Ch7).
16. If for any reason the results fall outside this range even after repeating the test, contact
Magee Scientific, Aerosol Co., or your authorized distributor.
