Operating instructions
IRF 650-12DIP IR-Thermometer
Item no. 1575717
Intended use
The infrared thermometer allows contactless measurement of surface temperatures. It mea-
sures the temperature by means of the infrared energy emitted by each object. It is especially
useful for measuring the temperature of objects that are hot, difficult to access or moving.
It cannot measure through transparent surfaces such as glass, plastics, water, etc. On the
contrary, it always measures the surface temperature. The temperature measurement range is
between -35 to +650 °C. A dual laser targeting device facilitates the specification of the mea-
surement range. The thermometer itself must not come in contact with the surface or object
to be measured. Always maintain sufficient safety distance and observe the permitted ambient
conditions. A 9 V block battery (type E) is required for the voltage supply. Do not use any other
source of energy (e.g., rechargeable batteries, etc.) than the one specified.

Dear Customer,
The following safety instructions are intended not only for the protection of your
health, but also for the protection of the device. Therefore, please read this chapter
very carefully before using the product for the first time!
a) General information
• For safety and licensing reasons, unauthorised conversion and/or modifications to
the product are not permitted.
• The appliance should not be exposed to strong vibration or heavy mechanical
stress.
• Do not expose the product to electromagnetic fields, extreme temperatures, direct
intense solar radiation or moisture.
• Do not expose the product to high humidity or liquids. During outdoor use, the
appliance must only be operated when the weather conditions are suitable and
only with the appropriate safety devices.
• Moisture, dust, fume and/or vapours can affect the optics of the thermometer and
thus the measured results.
• Failure to observe the operating instructions can result in accidents caused by
hazardous radiation (laser class 2).
• The device should not be used immediately after it has been brought from a cold
ambient temperature into a warm room. Condensation may destroy the device.
Likewise, the lens may become misty, which can lead to inaccurate measure-
ments. Wait until the product has reached ambient temperature before using it.
• If you should have reasons to assume that safe opeleveln is no longer ensured,
turn off the device and secure it against accidental use. Safe operation is no longer
ensured, when:
- the device shows visible signs of damage,
- the device no longer functions or
- the product has been stored under unfavourable conditions for a longer period
of time,
- the product has been exposed to strong stresses during transport.
• The product is not a toy. Keep it away from children and pets!
• On industrial sites, the accident prevention regulations of the association of the
industrial workers' society for electrical equipment and utilities must be followed.
• In schools, training facilities, hobby and self-help-workshops, the operation of
electric appliances is to be supervising by trained personnel.
• When operating the laser equipment, always make sure that the laser beam is
directed so that no one is in the projection area and that unintentionally reflected
beams (e.g., from reflective objects) cannot be directed into areas where people
are present.
• Laser radiation can be dangerous, if the laser beam or a reflection enters the
unprotected eye. Therefore, before using the laser equipment, familiarise yourself
with the statutory regulations and safety instructions for operating such a laser
device.
• Never look into the laser beam and never point it at people or animals. Laser
radiation can cause eye injuries.
• If laser radiation reaches the eyes, the eyes must be closed immediately and the
head has to be moved out of the laser beam.
• Should your eyes feel irritated from laser radiation, do not perform any safety-
related tasks such as operating machinery, working at high altitudes or close to
high-voltage. Do not drive any vehicles until the irritation has subsided.
• Do not point the laser beam at mirrors or other reflective surfaces. The uncont-
rolled, reflected beam may strike people or animals.
• Never open the device. Adjustment or maintenance tasks must be carried out
only by a trained specialist familiar with potential hazards. Improperly performed
adjustments might result in dangerous laser radiation.
• Caution: if operation settings or procedures other than those described in these
instructions are used, it could lead to exposure to dangerous radiation.
• The product is equipped with a class 2 laser. Laser signs in different languages
are included in the package.
• If the sign on the laser is not written in the language of your country, please affix
the appropriate sign onto the laser.
• Maintenance, adjustment, or repair may only be carried out by a specialist work-
shop.
• Our technical support is available, if you have queries about the use of the device,
which have not been answered in these operating instructions.
• Diagnostic application for medical purposes is not admissible.
b) Batteries
• Remove the batteries, if you are not going to use the device for a while, to prevent
damage from leaking. Leaking or damaged batteries can cause acid burns upon
contact with the skin. Therefore, you should wear protective gloves when handling
damaged batteries.
• Keep them out of the reach of children. Do not leave batteries lying around. There
is a risk that the batteries may be swallowed by children or pets.
• Do not dismantle batteries, do not short-circuit them or throw them into a fire.
Never try to charge batteries. There is a risk of explosion.
