Description on front of packaging
Dual-Temp. Infrared Thermometer ith needle sensor
• Touch- ree in rared thermometer or measuring sur ace temperatures
• Collapsible thermal needle sensor or measuring internal temperature
• Min./max. memory unction
• Stay-on unction or longer measurements
• Automatic-o unction, battery charge indicator

Instructions for use
The thermometer is a touch- ree in rared thermometer equipped with a needle
thermal sensor. It can only unction in one mode at a time, but those modes can
be switched as desired.
• Pressing the begin in rared measurement button ⑥: immediately activates
the touch- ree in rared thermometer unction (IRT mode).
• Pressing the begin needle sensor measurement button ⑦: immediately
activates the contact thermometer unction (COT mode).
To switch directly rom COT mode to IRT mode, press
button ⑥ when COT is in "Standby mode (Hold)".

Infrared touch-free thermometer function (IRT mode)
Set the thermometer using ③ on the object being measured and press
button ⑥ to display the sur ace temperature. The proportion o distance to
target is 1:1. This is why the thermometer should be held as close as
possible to the object being measured.
MINIMUM AND MAXIMUM MODE
While taking measurement the thermometer will display the
minimum or maximum value until button ② is pressed.
To activate minimum mode press ⑥-②-⑥. Press button ⑥ to begin
measurement.
To activate maximum mode press ⑥-②* twice-⑥. Press button ⑥ to begin
measurement.
Stay-on function
The stay-on unction is use ul or measuring temperatures over longer
periods o time. The thermometer displays the temperature constantly or
a period o up to 60 minutes or until button ⑥ is pressed.
To activate the stay-on unction press ⑥-②* three times-⑥.
°C OR °F MODE
To switch between °C (Celsius) and °F (Fahrenheit), press ⑥-②* our
times- ⑥.

EMISSION STRENGTH
The in rared thermometer comes actory preset at an emission strength o 0.95.
This value can be changed by 0.10 (10E) up to 1 (100E). These changes can be
made only by specially-trained personnel. In ormation concerning emission
levels o particular materials can be received rom your local sales agent.
Tip: The touch- ree in rared thermometer should not be used or measuring
temperatures o shiny or polished metallic sur aces. To change the emission
strength, press ⑥-②* ive times -⑥ or each change o 0.01 (1 E) -②.
Touch thermometer function (COT mode)
Insert the needle sensor ① into the object being measured and press ⑦ to
display the temperature or up to 4 minutes. A ter this time, the unit will
turn o automatically to save battery power. Pressing ⑦ will stop the
measurement and display the last temperature along with the message
“Hold”. To resume measurement, press ⑦ again.
1. Do not bend or rotate the needle sensor in the wrong direction.
2. Placing too much pressure on the sensor may cause damage.
STORAGE AND CLEANING
The sensor lens is the most sensitive element o the thermometer, and as
such must be kept clean. Clean the device care ully, using a so t cloth or
cotton swab dipped in water or pharmaceutical alcohol. Wait or the lens
to dry thoroughly be ore using. Do not immerse the thermometer in
luids. Store the unit at temperatures between -4°F and +149°F
(-20°C and +65°C).

ERROR MESSAGES- LCD
The thermometer displays the ollowing diagnostic messages:
"Hi"
or
"Lo"
is displayed when the measured
temperature exceeds the unit’s range. “Hi” i the
temperature exceeds +428°F (+220°C) and "Lo" i it
alls below -27°F (-33 °C) (both in touch- ree in rared
mode) (In “touch needle sensor mode” t
he LCD display
shows "Hi" when the temperature exceeds +626°F
(+330 °C) and "Lo" when it alls below 67°F (-55°C).
When any error message appear it is necessary to reset the thermometer.
To reset the thermometer, turn the unit o , remove the battery and wait at
least one minute be ore replacing the battery and turning the unit on. I the
error message continues to display, contact your customer service agent.
BATTERY
The thermometer is equipped with a batter charge indicator:
„ Sufficient battery
charge “: „
Low battery charge “: „ Empty battery “:
Measurements can be
taken.
Battery should be
replaced soon but
measurements can still
be taken
No measurements
can be taken
When the "
Lo battery charge
” indicator comes on, replace
the battery with an appropriate lithium battery type CR2032.
Remember: Before replacing the battery, turn the unit off.
Failure to do so can result in malfunctioning of the unit.

Dispose of the used battery properly.
