Note: Measurement considerations
• Holding the meter by its handle, point the IR Sensor towards 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
temperatures 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.
• This is a result of the cooling process, which must take place for the IR
sensor.
