2.3.1Adjusting Emissivity

°F

Refer to Appendices B and C for information on emissivity.

1.Determine the emissivity of the target.

2.Aim at the target and pull the trigger.

3.If necessary, press the key to increment the target

emissivity or press the key to decrement the target emissivity.

NOTE

The Emissivity Display Mode (E) appears every time the trigger is pulled regardless of how the Display Mode was previously set.

NOTE

The emissivity setting does not change when the thermometer is turned off. However, when the batteries are replaced, the emissivity is reset to 0.95, the default value.

2.3.2 Using the LOCK Function

This function electronically locks the trigger mechanism:

1.Pull the trigger and press the key to lock the trigger. The

icon will appear on the display.

2.Release the trigger. This allows the thermometer to operate continuously whether or not the trigger is pulled.
