In its battery compartment,
the 00911 has a switch that selects operation as Channel 1, 2, or 3 and
a button that selects either °F or °C for the 00911's own temperature
display. Regardless of the temperature unit selected on the 00911, the
associated main station displays temperatures in the unit for which it
is optioned. A second button labeled Tx in the battery compartment initiates
temperature data transmission. The red LED on the front of the 00911
lights when transmission is occurring. The temperature
measuring range of the 00911 is -4°F to +122°F (-20°C to +50°C) when
equipped with alkaline batteries. Temperature resolution is 0.1°F/C. The relative humidity measuring range is 20% to 99%
with 1% resolution. The
00911 remote sensor can transmit up to 100 feet (30 meters) in an open
area with no interference. Normal walls should not reduce this range by
much, but metal and heavy concrete walls can reduce the range
significantly. Even though the 00911 is weather-resistant, it is not
waterproof and should be mounted in a location where it is protected
from direct sunlight and direct precipitation (and this is stated in
bold on the back of the package!). For
powering, the 00911 requires two AA (1.5V) alkaline batteries (not
included). Expected battery life is about 1 year. If temperatures are
expected to remain below freezing for an extended time, we recommend
using lithium AA batteries instead of alkaline. The display on the remote
may fade, but the remote should continue measuring and sending
temperature and humidity data. When the temperature warms back up, the display will
return. This
remote temperature sensor is ideal for practically any indoor or
outdoor application that does not require a probe. The Acu-Rite
00911 comes with mounting screws and a 1-year factory
warranty.
