3Using the Infrared Thermometer/Transmitter
3.5.6Using Ambient Target Temperature Compensation (OS552, OS553, OS554)
AT C°F
Use the Ambient Target Temperature Compensation (AMB) Display Mode when high accuracy readings under both of these conditions are required:
•The target has a low emissivity.
•The ambient temperature around the target is much higher than the ambient temperature around the infrared thermometer.
To set and activate the Ambient Target Temperature Compensation Mode:
1.With power applied to the unit, set the emissivity to 1.0
2.Press and hold the 
key until the Average Display Mode (AVG) appears.
3.Slowly move the thermometer so that the line of sight sweeps across the area surrounding the target. The thermometer measures the temperature at each point on the surrounding area.
4.Read the average temperature value from the upper display and record it here __________.
5.Press and hold the 
key until the Ambient Temperature Display Mode (AMB) appears.
6.Set the AMB temperature found in Step 4 by pressing the
key or the 
key.
7.Press the 
key to enable the ambient target
temperature compensation. The 
icon appears on the display.
