W Caution
The optical surfaces of the lens are equipped with
high-quality optical layers. Avoid any contact with
these surfaces and protect these surfaces against
dirt and damage.
How to Clean the Case
Clean the case with a clean, damp cloth. Do not use abrasives,
isopropyl alcohol, or solvents to clean the case or lens/window.
Acoustic Sensor Care
W Caution
The Imager has highly-sensitive acoustic
sensors. Do not expose the sensors to water or
fluids, dust, and other contaminates.
Accumulation of these in the sensor will affect the
performance.
Always keep the Acoustic Sensor protected with the provided
cover when the Imager is not in use. Avoid grease or liquids on the
microphones. If the microphones are dirty or clogged, carefully
clean with low air pressure from a compressed air duster at 25 cm
to 30 cm (10 in to 12 in) distance. Avoid too much air pressure.
To check the microphones:
1. Go to Settings menu.
2. Select Test Microphones.
If you see a warning message for service:
1. Clean the microphones with an air duster.
2. Test the microphones again. If the message continues,
contact a Fluke Service Center. See Contact Fluke for more
information.
