4. Measurement Considerations
Holding the meter by it's handle, point the IR sensor toward the
object whose temperature is to be measured.
The meter automatically compensates for temperature deviations
from ambient temperature. Keep in mind that it will take up to 30
minutes to adjust to wide ambient temperature changes. When low
temperatures are to be measured followed by high temperature
measurements some time (several minutes) is required after the low
(and before the high) temperature measurements are made.
