Technical Data - VOLTCRAFT IR 500-12D Bedienungsanleitung

Operation
a) Switching on/off
• Press the measurement trigger to switch the product on.
• The product turns off automatically after 10 seconds of inactivity.
b) Target laser/display lighting
• Repeatedly press the laser button to set the target laser and/or to activate/deactivate the
display lighting.
• If the laser function is enabled, a warning triangle appears on the top of the display .
• The laser beam is generated only when the measurement trigger is held pressed. If you
release the measurement trigger, the laser beam goes out.
c) Measuring procedure
• Press and hold the measurement trigger and point the infrared sensor directly at the object.
• During measurement, the temperature and the indicator SCAN is shown on the display.
• When the measurement trigger is released, the last measured value is frozen on the display.
The indicator HOLD also appears.
• If the temperature lies outside the measurement range, four horizontal dashes appear on the
display instead of a measured value.
In order to obtain exact measured values, the infrared thermometer has to be
adjusted to the ambient temperature. If you relocate the product, let it adjust to the
ambient temperature first before using it.
Longer measurements of high temperatures, with close measuring distance, cause
the thermometer to self-heat and thus result in inaccurate measurements. In order
to obtain exact measured values, remember the following rule of thumb: The higher
the temperature, the greater the measuring distance and the shorter the measuring
time should be.
d) Changing the unit
Press and hold the SET button for approx. one second to switch between display in °C
(Celsius) and °F (Fahrenheit).
e) MIN./MAX. display
• The minimum or maximum value of the current measurement is shown at the bottom right
of the display.
• Press the SET briefly to switch between displaying the minimum (indicator MIN) and
maximum (indicator MAX) measured value.
• Releasing the measurement trigger and then pressing it again starts a new measurement.
The buffer is reset and the MIN/MAX values of the previous measurement are no longer
available.
f) Setting the emissivity
• The emissivity is shown at the bottom left of the display.
• Press the ▲ or ▼ button to change the emissivity.
Many organic materials have an emissivity of 0.95. Therefore, the preset emissivity
is 0.95 ex works.
Check the table under "Technical data" to determine whether the setting should be
adjusted to obtain an accurate measuring result.
IR measuring spot size (ratio of measurement distance to the measured
surface)
• In order to obtain precise measuring results, the measured object must be larger than the
IR measuring spot.
• The smaller the object, the closer it must be to the thermometer.
• To ensure precise measurements, the measured object should be at least twice the size of
the IR measuring spot.
• For this product, the ratio is 12:1. At a distance of 12 cm, the size of the measuring spot is
1 cm.
Care and cleaning
a) Housing
• Never use aggressive detergents, rubbing alcohol or other chemical solutions, as these may
damage the casing or cause the product to malfunction.
• Use a dry, lint-free cloth to clean the product.
b) Lens
• Do not use any acidic, alcoholic or other solvents or rough, linty cloth to clean the lens.
• Avoid applying too much pressure when cleaning the lens.
• Remove loose particles with clean compressed air and wipe off remaining residues with a
fine lens brush.
• Clean the surface using a lens cloth or a clean, soft, lint-free cloth.
• The cloth can be moistened with water or a lens cleaning solution to remove fingerprints and
other residues.
Disposal
a) Product
This symbol must appear on any electrical and electronic equipment placed on the
EU market. This symbol indicates that this device should not be disposed of as
unsorted municipal waste at the end of its service life.
Owners of WEEE (Waste from Electrical and Electronic Equipment) shall dispose
of it separately from unsorted municipal waste. Spent batteries and accumulators,
which are not enclosed by the WEEE, as well as lamps that can be removed from
the WEEE in a non-destructive manner, must be removed by end users from the
WEEE in a non-destructive manner before it is handed over to a collection point.
Distributors of electrical and electronic equipment are legally obliged to provide free take-back
of waste. Conrad provides the following return options free of charge (more details on our
website):
in our Conrad offices
at the Conrad collection points
at the collection points of public waste management authorities or the collection points set
up by manufacturers or distributors within the meaning of the ElektroG
End users are responsible for deleting personal data from the WEEE to be disposed of.
It should be noted that different obligations about the return or recycling of WEEE may apply in
countries outside of Germany.
b) Batteries
Remove batteries/rechargeable batteries, if any, and dispose of them separately from the
product. According to the Battery Directive, end users are legally obliged to return all spent
batteries/rechargeable batteries; they must not be disposed of in the normal household waste.
Batteries/rechargeable batteries containing hazardous substances are labelled with
this symbol to indicate that disposal in household waste is forbidden. The abbrevia-
tions for heavy metals in batteries are: Cd = Cadmium, Hg = Mercury, Pb = Lead
(name on (rechargeable) batteries, e.g. below the trash icon on the left).
Used (rechargeable) batteries can be returned to collection points in your municipality, our
stores or wherever (rechargeable) batteries are sold. You thus fulfil your statutory obligations
and contribute to environmental protection.
Batteries/rechargeable batteries that are disposed of should be protected against short circuit
and their exposed terminals should be covered completely with insulating tape before disposal.
Even empty batteries/rechargeable batteries can contain residual energy that may cause them
to swell, burst, catch fire or explode in the event of a short circuit.
