English Warning
Do not point laser directly at eye or indirectly off
reflective surfaces.
Cautions
Use this unit only as specified in this manual or the
protection provided by the unit may be impaired.
All models should be protected from the following,
▲EMF (electro-magnetic fields) from arc welders,
induction heaters
▲Static electricity
▲Thermal shock (caused by large or abrupt ambi-
ent temperature changes—allow 30 minutes for
unit to stabilize before use)
▲Do not leave the unit on or near objects of high
temperature
Introduction
We are confident you will find many uses for your
handheld noncontact thermometer. Compact, rugged,
and easy to use—just aim, press the trigger, and read
surface temperatures in less than a second. You can
safely measure surface temperatures of hot, hazardous,
or hard-to-reach objects without contact.
How it Works
Infrared thermometers measure the surface tempera-
ture of an object. The unit’s optics sense emitted (E),
reflected (R), and transmitted (T) energy, which is
collected and focused onto a detector. The unit’s
electronics translate the information into a temperature
reading which is displayed on the unit. The laser is
used for aiming purposes only.

How to Operate the Unit
°C/°F and Battery
Open the battery compartment to access the C/F
switch or to insert/remove the battery. To switch
between °C and °F, toggle the switch (A). Insert the
9v battery positive side first into the battery
compartment.
Operating the Unit
To measure a temperature, point unit at object and
press the On Button. Be sure to consider distance-
to-spot size ratio and field of view. If the unit is
equipped with a laser, use the laser only for aiming.
See ‘How to Accurately Measure Temperatures’.
Display
The backlit LCD displays the current temperature in
Celsius or Fahrenheit. The unit will hold the reading
for 7 seconds after the On Button is released; the word
HOLD appears. The presence of the battery icon
indicates a low battery (B).

English How to Accurately Measure
Temperature
Locating a Hot Spot
To find a hot spot aim the thermometer outside the
area of interest, then scan across with an up and
down motion until you locate the hot spot.
Field of View
Make sure that the target is larger than the unit’s spot
size. The smaller the target, the closer you should be
to it. When accuracy is critical, make sure the target
is at least twice as large as the spot size.
Distance & Spot Size
As the distance (D) from the object increases, the
spot size (S) of the area measured by the unit
becomes larger.
Reminders
■Not recommended for use in measuring shiny
or polished metal surfaces (stainless steel,
aluminum, etc.). See Emissivity.
■The unit cannot measure through transparent
surfaces such as glass. It will measure the
surface temperature of the glass instead.
■Steam, dust, smoke, etc., can prevent accurate
measurement by obstructing the unit’s optics.

Emissivity
Most organic materials and painted or oxidized surfaces have an emissivity of
0.95 (pre-set in the unit). Inaccurate readings will result from measuring shiny or
polished metal surfaces. To compensate, cover the surface to be measured with
masking tape or flat black paint. Allow time for the tape to reach the same tempera-
ture as the the material underneath it. Measure the temperature of the tape or paint-
ed surface.
Maintenance
Lens Cleaning: Blow off loose particles using clean compressed air. Gently brush
remaining debris away with a camel's hair brush. Carefully wipe the surface with a
moist cotton swab. The swab may be moistened with water.
NOTE: DO NOT use solvents to clean the plastic lens.
Case Cleaning: Use soap and water on a damp sponge or soft cloth.
NOTE: DO NOT submerge the unit in water.

Warnung (bei Geräten mit Laser)
Richten Sie den Laser nicht direkt oder indirekt über
reflektierende Oberflächen auf die Augen.
Vorsichtsmaßnahmen
Alle Modelle müssen vor folgenden Zuständen
geschützt werden:
▲EMF (elektromagnetische Felder) von
Elektroschweißgeräten, Induktionsheizgeräten
▲statischer Elektrizität
▲Thermischer Schock (verursacht durch große oder
plötzliche Temperaturänderungen – Gerät vor
Gebrauch 30 Minuten lang stabilisieren lassen)
▲Gerät nicht auf oder in der Nähe von heißen
Objekten aufbewahren.
Einführung
Wir sind überzeugt, daß Sie für Ihr handgehaltenes
berührungsloses Thermometer zahlreiche
Anwendungen finden werden. Kompakt, robust und
einfach zu bedienen – einfach auf das Ziel richten,
den Knopf drücken, und in weniger als einer Sekunde
können Sie die momentane Oberflächentemperatur
ablesen. So lassen sich die Oberflächentemperaturen
von heißen, gefährlichen oder schwer erreichbaren
Objekten gefahrlos und ohne Berührung bestimmen.

Deutsch Funktionsweise
Infrarot-Thermometer messen die Oberflächen-
temperatur eines Objekts (target). Die Optik des
Gerätes erfaßt die emittierte (E), reflektierte (R) und
durchgelassene (T) Wärmestrahlung, die gebündelt
und auf einen Detektor fokussiert wird. Die
Geräteelektronik wandelt diese Information in einen
Temperaturwert um, der auf dem Display angezeigt
wird. Der Laser wird lediglich zum Zielen verwendet.
Bedienung des Gerätes
°C/°F und Batterie
Um zwischen Celsius und Fahrenheit umzuschalten,
müssen Sie das Batteriefach öffnen und mit dem
Schalter (A) C oder F wählen. Die 9-Volt-Batterie
wird wie in der Abbildung dargestellt, ausgetauscht.
Bedienung des Gerätes
Zur Temperaturbestimmung wird das Gerät auf ein
Objekt gerichtet und die Meßtaste gedrückt. Denken
Sie daran, das Verhältnis von Entfernung zu
Punktgröße sowie das Sichtfeld zu berücksichtigen.
Falls das Gerät mit einem Laser ausgerüstet ist,
benutzen Sie den Laser bitte nur zum Zielen. Siehe
Abschnitt „Korrekte Temperaturbestimmung“.
Anzeige
Die LCD-Anzeige zeigt die momentane Temperatur in
Grad Celsius oder Grad Fahrenheit an. Nach Freigabe
der Meßtaste wird der Meßwert weitere 7 Sekunden
lang angezeigt; dabei wird das Wort HOLD angezeigt.
Die Anzeige des Batteriesymbols weist auf einever-
brauchte Batterie hin (B).
