5. The HAL (high alarm) will now flash. Use the up and down arrows
to select the high temperature limit. When the temperature is
exceeded, the alarm will activate.
6. Push the ALM button. The LAL (low alarm) will now flash. Use the
up and down arrows to select the low temperature limit. When the

DISTANCE TO SPOT (FIG. 5)
IR Thermometers have a "Cone Effect" where the further the
thermometer is from the object, the larger the area being measured.
The IR Thermometer has a 12:1 distance to spot (12:1) ratio, for every
12" (305 mm) away from the object it will measure 1" (25 mm). The
object that is being tested needs to be larger then the spot size to
ensure accurate readings.

KEY NOTES IF HAVING TROUBLE TAKING MEASUREMENT
1. Make sure to apply masking tape or flat black paint to surfaces
that are highly reflective (use the default 0.95 emissivity setting).
2. Make sure to have the correct emissivity for the material you are
testing. Refer to Emissivity and Nominal Emissivity Table.
3. Clean the material before testing if there is heavy dirt, grease, etc.

Operating Tips

• Use only the 12V Max* D WALT lithium ion battery.
E
• Ensure batteries are in good working condition. If the low battery
indicator light is flashing, the batteries need to be recharged.
• To extend battery life, release the IR Thermometer trigger when not
taking temperature readings.

MAINTENANCE

WARNING: To reduce the risk of serious personal injury,
turn tool off and disconnect battery pack before making any
adjustments or removing/installing attachments or accessories.
Cleaning
WARNING: Blow dirt and dust out of all air vents with clean, dry air
at least once a week. To minimize the risk of eye injury, always wear
ANSI Z87.1 approved eye protection when performing this.
WARNING: Never use solvents or other harsh chemicals for
cleaning the non-metallic parts of the tool. These chemicals may
weaken the plastic materials used in these parts. Use a cloth
