The indoor sensor is less responsive to
ambient air currents because of the shielding
effect of the display's case. In addition, the
case can act as a heat sink to absorb and
store heat from external sources (i.e. handling
of the case or radiant heat). In addition, the
much greater range of the outdoor
temperature sensor requires a different
calibration curve than the indoor range. Error
is usually greater at the extreme ends of a
range, making it harder to compare different
ranges with different curves. Under non-
laboratory conditions, it is difficult to
compensate for the above factors and obtain
an accurate comparison.
MAINTENANCE AND CARE
9 Extreme temperatures, vibration, and
shock should be avoided to prevent
damage to the units.
9 Clean displays and units with a soft,
damp cloth. Do not use solvents or
scouring agents; they may mark the
displays and casings.
9 Do not submerge in water.
9 Do not subject the units to unnecessary
heat or cold by placing them in the oven
or freezer.
