Using the Handheld Infrared Thermometer 2

2.3.8Using Ambient Target Temperature Compensation (OS533, OS534, OS523, OS524)

ATC°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.Pull the trigger and press the key to lock the trigger. Set the emissivity to 1.0 (refer to Section 2.3.1).

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.

NOTE

To disable this mode, press the key again.

The icon disappears.
