We hope you enjoy using
your infrared thermometer!
It measures the amount of
infrared energy emitted by
a target object, and
calculates the temperature
of that object´s surface.
INTRODUCTION
Your thermometer includes:
- Laser sighting
- Adjustable emissivity
- High/Low Alarm
- MAX, MIN, DIF, AVG
- Data Logger (100 points)
- Trigger lock
- Graphic display ... and
more!

BATTERIES
To open the battery
compartment, press
gently on the top part of
the handle (1) to release
the catch (2) and pivot
the grip as shown in the
figure.
Orient the batteries (two
alkaline R6 (AA, UM3))
as shown on the housing.
MEASUREMENT
QUICK START
To take a temperature
measurement, hold the
unit as shown. Aim at the
target. Pull the trigger (F).
The temperature of the
object being measured is
shown on the display (B).
The temperature will be
displayed for seven
seconds after the trigger
is released.
The unit automatically switches “off” after
7 seconds if a function key is not pressed.
The last settings are stored. The display
returns to the last mode selected.
To recall the last reading, press ENTER
without pulling the trigger.

MEASUREMENT
CONTINUOUS
Open the battery compartment and switch LOCK
"on" to lock the unit on.
You may mount the unit on
a tripod, using the tripod
mount. Pull the trigger for
continuous temperature
measurement. (The laser
will not be locked on.)
To unlock, switch LOCK
off.
The measured spot size depends on the distance
between the object you are measuring and the infrared
thermometer. The relationship between distance and
spot size is 60:1 at the focus point. The D:S in the far
field (>33ft/10m) is 35:1.

The laser sight simplifies
sighting of the measurement object. It shows the
spot size that includes the
measured target.
To turn the laser on or off
press the LASER button
(K) when the trigger is
pulled. A laser symbol (1)
appears when the laser is
on. The laser automatically
turns off if you release the
trigger.

The amount of infrared
energy radiated by an
object depends on its
emissivity and its
temperature.
The emissivity depends on
the material and its surface
characteristics. For more
accurate readings, adjust
the emissivity value for
the type of material being
measured.
EMISSIVITY
EMISSIVITY EXPLAINED
To adjust the emissivity
value, press EMISS (P).
Use the Up and Down
keys to select “Free“
(“F
ree” will have a
flashing underline) (7).
Press EMISS again.
“Free” is not underlined,
and the emissivity icon (5)
flashes. Use the Up and
Down keys (C) to adjust.
Press ENTER (D) to
activate this setting.

EMISSIVITY
To adjust the unit’s
emissivity value for a
material with unknown
emissivity, plug in the
probe.
Pull the unit’s trigger.
Place the measuring
tip of the probe on the
area to be measured.
Wait for the reading to
stabilize.
EMISSIVITY
TABLE OF VALUES
To choose the emissivity
of a material, press
EMISS (P). The display
shows a material name
(7), an emissivity value,
and the calculated
temperature value (5). To
choose another material,
use the Up and Down
keys (C). Press ENTER
(D) to activate this setting.
EMISSIVITY
UNKNOWN VALUE
Note the indicated probe temperature reading.
Release the trigger. Pull the trigger again. Measure
the same area using infrared measurement. Press
the emissivity button (P). Use the Up and Down keys
(C) to select the material name “Free” which will be
shown in the display (7). Press the emissivity button
(P) again until the emissivity sign (5) flashes. Use
the arrow keys (C) to change the emissivity value
until the temperature matches the probe’s reading.
