VOLTCRAFT IR 500-12S Mode D'emploi page 4

Inserting/changing the battery
• Open the battery compartment lid.
• Connect the battery clip with the contacts of the battery.
• Slide the battery into the compartment.
• Close the battery compartment. Make sure that the cables of the
battery clip are not clamped.
Replace the battery as soon as the battery symbol appears
on the display.
Operation
a) Switching on/off
• Press the measuring button to switch the product on.
• The product turns off automatically after 10 seconds of inactivity.
b) Targeting laser
• Press and hold the laser button for approx. 1 second in order to activate or deactivate the
target laser.
• If the laser function is enabled, a warning triangle appears on the top of the display.
• The laser beam is generated only when the measuring button is held pressed. If you release
the measuring button, the laser beam goes out.
c) Measuring procedure
• Press and hold the measuring button and point the infrared sensor directly at the object.
• During measurement, the temperature and the indicator SCAN is shown on the display.
• When the measuring button 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) Display backlight
Press the laser button briefly to activate or deactivate the display lighting.
e) Changing the unit
Press the °C/°F button to switch between the display in °C (Celsius) and °F (Fahrenheit).
f) MIN./MAX. display
• The minimum or maximum value of the current measurement is shown at the bottom left of
the display.
• Press the MAX/MIN button to switch between displaying the minimum (indicator MIN) and
maximum (indicator MAX) measured value.
• Releasing the measuring button 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.
Emissivity
• Many organic materials have an emissivity of 0.95. Therefore, the preset emissivity is 0.95.
The emissivity is shown at the bottom right of the display.
• Shiny surfaces affect the measured result. To compensate, the shiny part of the surface can
be covered with adhesive tape or matt black paint.
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
Electronic devices are recyclable waste and must not be disposed of in the
household waste. Always dispose of the product according to the relevant statutory
regulations.
Remove any inserted batteries and dispose of them separately from the product.
b) Batteries
You are required by law to return all used batteries (Battery Directive). Batteries
must not be placed in household waste.
Batteries containing hazardous substances are labelled with this symbol to indicate
that disposal in household waste is forbidden. The abbreviations for heavy metals
in batteries are: Cd = Cadmium, Hg = Mercury, Pb = Lead (indicated on the battery,
e.g. below the trash icon on the left).
Used batteries can be returned to local collection points, our stores or battery retailers.
You thus fulfil your statutory obligations and contribute to protection of the environment.
