Required accessories:
A) Isopropyl Alcohol (91% or better)
B) Round
wooden
toothpick with sharp point
(NOTE: do not use a metal pin or needle since metal will scratch
the surface of the detector)
C) Cotton swab
D) Jeweler’s loupe (10x magnification recommended)
E) Compressed Air (not shown)
1) Remove the adapter cap from the power meter detector port.
2) Blow some of the compressed air into the small hole in the universal adapter.
3) Use the jewelers loupe to inspect the detector end face.
Repeat the above steps until the detector surface appears clean, then replace the universal
adapter cap.
If the detector surface is still dirty after using the compressed air:
4) Place a small amount of cotton from the swab onto the wooden toothpick
as shown at right.
5) Wet the cotton toothpick tip with the isopropyl alcohol.
6) USING GREAT CARE, gently insert the cotton toothpick tip into the detector port.
WARNING! BE VERY CAREFUL WHEN INSERTING THE TOOTHPICK INTO THE
DETECTOR PORT. THERE IS A VERY THIN GLASS WINDOW THAT WILL EASILY
BREAK WITH TOO MUCH PRESSURE.
7) Using as little pressure as possible, rotate the cotton toothpick tip in the detector port to
clear away any dust or dirt that has accumulated on the detector.
8) Using light pressure from the compressed air, blow out the detector port.
Repeat steps 4-8 until the detector port is free of debris, then replace the adapter cap on the detector port and cover the detector
port with the dust cap.
