Instructions / Assembly

Procedure:

hDrill two 3/16” diameter holes, one inch apart through

the siding.

hUsing the #21-E, insert the #608 contact pins into the

holes so that you make contact with the insulation.

hPress the read button

! and take a reading. Take read-

ings at various depths of penetration to determine the loca-

tion of moisture.

hFill holes with putty at the conclusion of the test.

Meters are not calibrated to read the percentage of moisture

content in the insulation. Instead, meter readings provide

a qualitative indication of the presence of moisture. The

meter may also help identify the pattern of distribution to

help you determine if moisture is due to condensation or

leakage.

The presence of moisture in insulating material greatly

reduces its insulating properties. If the insulating material

absorbs moisture, water will displace the air in the material.

Water also transmits heat at a faster rate than air, thus

reducing the efficiency of the insulation.

Side walls and roof insulation pick up moisture because

of leaks in the roof or structural defects in the side walls

which allow storm water to be forced in during high

wind. During periods of cold weather, vapor will condense

as it approaches the colder area near the outside walls,

and resulting moisture will remain trapped in the insulation.

Cork, wood fiber boards, and other cellulose material read

lower than glass wool and other inorganic types of insulation.

CARE OF YOUR METER

To keep your meter in good working order:

hStore your meter in a clean, dry place. The protective

carrying case provided is an ideal storage place when the

meter is not in use.

hChange the 9-Volt battery as needed. Continued use with a

low battery may cause the meter to go out of calibration.

hChange contact pins as needed. Keep pin retainers hand

tightened.

hClean the meter and contact pins with any biodegradable

cleaner. Use the cleaner sparingly and on external parts

only. Keep cleaner out of the external connector

hRemove the battery if the meter will not be used for one

month or longer.
