Detecting Moisture in Insulation:
Use the
BD-10 with the #21-E Electrode and #608 insulated pins to detect moisture in insulation. These pins are insulated,
except at the tips. Only the uninsulated tips make contact with the material, providing information as to the depth at which moisture
is present.
Procedure:

Drill two 4.8mm (
3
∕
16
”) diameter holes,
one inch apart through the siding.

Using the #21-E, insert the #608 contact pins into the holes so that you make contact with the insulation.

Press the read button and read the reference scale . Take readings at various depths of penetration to
determine the location of moisture.

Fill 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:

Store your meter in a clean, dry place. The protective carrying case provided is an ideal storage place when the meter is
not in use.

Change the 9-Volt battery as needed. Continued use with a low battery may cause the meter to go out of calibration.

Change contact pins as needed. Keep pin retainers hand tightened.

Clean 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 .

Remove the battery if the meter will not be used for one month or longer.
