Omega Engineering OMEGASCOPE OS533 - Manual (Page 27)

2.3.1 Adjusting Emissivity
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.
The Emissivity Display Mode (E) appears every time the
trigger is pulled regardless of how the Display Mode was
previously set.
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.
To unlock the trigger function, press the key again,
and the icon is no longer displayed.
