Storage Recommendations; Laser Information - DeWalt DCT414 Instruction Manual

4. The battery pack should be recharged when it fails to produce
sufficient power on jobs which were easily done previously. DO
NOT CONTINUE to use under these conditions. Follow the
charging procedure. You may also charge a partially used pack
whenever you desire with no adverse affect on the battery pack.
5. Foreign materials of a conductive nature such as, but not limited
to, grinding dust, metal chips, steel wool, aluminum foil, or any
buildup of metallic particles should be kept away from charger
cavities. Always unplug the charger from the power supply
when there is no battery pack in the cavity. Unplug charger
before attempting to clean.
6. Do not freeze or immerse charger in water or any other liquid.
WARNING: Shock hazard. Don't allow any liquid to get inside
charger. Electric shock may result.
CAUTION: Never attempt to open the battery pack for any
reason. If the plastic housing of the battery pack breaks or cracks,
return to a service center for recycling.

Storage Recommendations

1. The best storage place is one that is cool and dry away from
direct sunlight and excess heat or cold.
2. For long storage, it is recommended to store a fully charged
battery pack in a cool dry place out of the charger for optimal
results.
NOTE: Battery packs should not be stored completely depleted of
charge. The battery pack will need to be recharged before use.

Laser Information

The Infrared Thermometer (IR thermometer) is a Class 2 laser product
and complies with 21 CFR 1040.10 and 1040.11 except for deviations
pursuant to laser notice No. 50, dated June 24, 2007.
Emissivity
Emissivity describes the energy-emitting characteristics of materials.
Most organic materials and painted or oxidized surfaces have
an emissivity of about 0.95 which is the default setting. It is
recommended to compensate for inaccurate readings that may result
from measuring materials with low emissivity values such as shiny
metal surfaces. Cover these surfaces with masking tape or flat black
paint (<148°C/300°F) and use the default (0.95) setting. Allow time
for the tape or paint to reach the same temperature as the surface
beneath it and then measure the temperature of the tape or painted
surface.
If you cannot paint or use tape, then you can compensate your
measurements with the emissivity selector. Even with the adjustable
emissivity, it can be difficult to get a completely accurate infrared
measurement of a target with a shiny or metallic surface. Experimentation
may be required to benchmark temperatures, and experience will help
you choose the best setting for specific measurements.
The thermometer has emissivity adjustable from 0.1 to 1.0 in increments
of 0.01. Refer to the Nominal Emissivity Table in this manual. The
reference to emissivity settings in the table are suggestions for typical
situations and your particular situation may differ.
NOTE: Calibration of this product was performed at 0.95 emissivity.
