WARNING! Read all safety warnings and all
instructions, including those given in the accompanying
brochure. Failure to follow the warnings and instructions may
result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
SAFETY INSTRUCTIONS
Do not stare into beam. Do not point laser light at other
persons.
Do not view directly into beam with optical instruments
(binocular, telescope).
Do not point laser at reflective surfaces,
Avoid exposure to laser radiation. Laser may
emit hazardous radiation.
Avoid dangerous environments. Do not use in rain, snow, damp
or wet locations. Do not use in the presence of explosive
atmospheres (gaseous fumes, dust or fammable materials)
because sparks may be generated when inserting or removing
battery pack, possibly causing fire.
Disconnect all the cords and cables from the object under test
and power off the instrument before removing or inserting the
battery pack.
Do not dispose of used battery packs in the household refuse
or by burning them. Milwaukee Distributors offer to retrieve old
batteries to protect our environment.
Do not store the battery pack together with metal objects (short
circuit risk).
Use only System C 12 chargers for charging System C 12
battery packs. Do not use battery packs from other systems.
Battery acid may leak from damaged batteries under extreme
load or extreme temperatures. In case of contact with battery
acid wash it off immediately with soap and water. In case of eye
contact rinse thoroughly for at least 10 minutes and
immediately seek medical attention.
This appliance is not intended for use by persons (including
children) with limited physical, sensory or mental capabilities or
insufficient experience and/or knowledge unless they are
supervised by a person who is responsible for their safety or

have been instructed by them in the safe use of the tool.
Children should be supervised in order to ensure that they do
not play with the tool.
SPECIFIED CONDITIONS OF USE
The Laser Thermoemter can be used for non-contact
temperature measurement or contact temperature
measurement with K-type probe.
Do not use this product in any other way as stated for normal
use.

OPERATION
Scanning Object IR Temperature
1. Pull and hold the trigger for at least 2
seconds and scan the surface
temperature of an object. A laser
pointer indicates the center of the
circular area being scanned.
NOTE: The object should be larger
than the spot being scanned. If not,
readings will be affected. See Distance
To Spot for necessary object size.
2. As you continue to hold the trigger, the icon is displayed
along with the surface temperature (primary measurement) and
maximum temperature (secondary measurement) readings.
3. Release the trigger. HOLD is
displayed until the screen shuts off in
about seven seconds.
NOTE: A quick change in temperature
(>10°C) affects the meter's readings.
Allow the meter to reach ambient
temperature before use (5 to 30
minutes, depending on temperature
change).
SELECTING MODES
Press the MODE button to display one of the following
Average Temperature (AVG)
During a temperature reading, the
average temperature read during the
scan is displayed.
Maximum Temperature (MAX)
During a temperature reading, the
highest temperature read during the
scan is displayed.
Minimum Temperature (MIN)
During a temperature reading, the
lowest temperature read during the
scan is displayed.
Humidity (RH)
During a temperature reading, the
relative humidity (RH%) read during
the scan is displayed. The relative
humidity is taken at the meter, not at
the point of the temperature reading.
Dew Point Temperature (DEW)
During a temperature reading, the dew
point read during the scan is displayed.
The dew point is taken at the meter,
not at the point of the temperature
reading.
CONTACT TEMPERATURE MEASUREMENT WITH K-TYPE
PROBE
Warning!
Never connect the Temperature Probe to an energized circuit.
Only use K-type Temperature Probes with this meter.
1. Insert the probe. P ull the trigger. The unit detects a
connection of a K-type probe and displays the contact
temperature (CON) as the secondary measurement.
2. The display will continue to update the contact temperature
(CON) while the temperature probe reaches thermal equilibrium
with the object being measured. The display will shut off after
about 20 min.
3. When the probe is inserted, both IR
and contact temperature reading will
continue to display as primary and
secondary measurement respectively.
Removing the probe will set the unit off
and turn on to default IR reading when
pull the trigger.
4. If set, the alarm will alert for the IR
reading regardless the sensor probe is
installed or not.
SELECTING SETTINGS
Press the SET button to display one of the following. Then use
the arrow buttons to determine the value:
Alarm High (HI)
If the set temperature is reached during
a scan, "HI", , and temperature will
flash.
