4.3 Operating Test
For a quick verification that the thermometer is functioning correctly, point it at
water containing ice cubes, since this provides a simple reference for 32°F (0°C).

WARNING:
Never point the LASER target beam at someone's eyes!
1. Activate the laser by briefly depressing the trigger.

buttons.
3. Select a measurement unit.
4. Point the thermometer at the object whose temperature you wish to measure,
with or without using the LASER target.
