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). Also, 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
INSTRUCTIONS
•
Extreme temperatures, vibration, and
shock should be avoided to prevent
damage to the units.
•
Clean displays and units with a soft,
