Measuring Operation
1. Hold the Thermometer in your hand, point the Laser Pointer (2) and Infrared Sensor (1)
toward the object to be measured. The Thermometer will automatically compensate for
temperature deviations from ambient temperature. Note: It will take up to 30 minutes
to adjust to wide ambient temperature measurements, followed by high temperature
measurements. Sometimes several minutes are required after the low or high temperature
measurements are made; a cooling process must take place for the Infrared Sensor
(1). See Figure 5.
