Using the Handheld Infrared Thermometer 2

2.3.1 Adjusting 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 C F 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 LOCK key to lock the trigger in the Emissivity

and Distance Display Mode. 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.

NOTE

To unlock the trigger function, while in Emissivity and

Distance Display Modes press the LOCK key again, and

the icon is no longer displayed.

The LOCK key also enables/disables alarm functions, and resets calculated temperature values (MAX, MIN, dIF, AVG).

2.3.3 Using the Trigger Function

Besides turning on the thermometer by pulling the trigger, you can lock the trigger electronically by pressing the trigger button twice.

The icon is displayed. You can unlock the trigger by pressing the trigger button twice again.
