Setup

a) Inserting/replacing the battery

• Insert the battery before using the thermometer for the first time. Replace the battery when the low battery indicator [empty battery] (F) is displayed.
• Press the locking latch (6) inwardly on both sides at the same time and pull the battery compartment cover (7) downwards, in order to open the battery compartment (8).
• Remove the used battery from the compartment and insert a new battery of the same type in the correct polarity. The battery clip is designed so the battery can be only be connected in the correct polarity. Do not use force when plugging the battery in onto the contacts.
• Stow the battery in the battery compartment (8).
• Close the battery compartment (8) by closing the battery compartment cover (7) using the locking latch (6). Be careful not to pinch the cables.

b) Function

• Infrared thermometers measure the surface temperature of an object. The sensor on the product records the heat radiation emitted, reflected and transmitted through the object, and converts this information into a temperature value.
• Temperature measurements on shiny or reflective surfaces are imprecise. Transparent materials cannot be measured. To measure such materials, apply a layer of opaque adhesive paper tape to the object, allow the tape to reach the temperature of the object, and then measure the surface temperature of the transparent object at the taped location.
• Emissivity is used to describe the energy emission characteristics of a material. The higher the emissivity, the more radiation a material can emit. Many organic materials and surfaces have an emission level of approx. 0.95. Metallic surfaces or shiny materials have low emissivity. This results in imprecise measuring values.
• The thermometer's emissivity settings cannot be changed.

Emissivity of different surfaces

The emissivity levels listed in the following table are approximate values. Parameters such as the shape and characteristics of the material can affect the emissivity of an object. Measuring materials with an emissivity that is different from the preset emissivity may lead to slightly inaccurate readings.

Surface Emissivity	Surface Emissivity
Asphalt	0.90 – 0.98	Plastic	0.85 – 0.95
Varnish (matt)	0.97	Hard plaster	0.80 – 0.90
Concrete	0.94	Sand	0.90
Human skin	0.98	Glass/ceramics	0.90 – 0.95
Ice 0.96 – 0.98	Textiles	0.90
Mortar	0.89 – 0.91	Rubber (black)	0.94
Ferric oxide	0.78 – 0.82	Water	0.92 – 0.96
Paper	0.70 – 0.94	Varnish	0.80 – 0.95
Soil/humus	0.92 – 0.96	Bricks	0.93 – 0.96

c) Switching on

- Press the trigger (1) to switch on the infrared thermometer.

The product must first adjust to the ambient temperature, in order to be able to supply precise measurement values. When using the product in a new location, wait until it has had time to adjust to the new ambient temperature.

d) Measurement of surface temperatures

- For a measurement, point the infrared sensor (2) and the laser outlet (3), preferably perpendicular to the object to be measured. Make sure that the object to be measured is not smaller than the product IR measuring spot (see "e) IR measuring spot size - distance-to-spot ratio; D/S"). - Press the trigger (1) and hold it down while it takes measurements and until the measured value in the LCD display (4) has stabilized. "SCAN" (D) will appear on the display while the temperature is being measured. The temperature displayed is the surface temperature of the measured object. The symbol for the object temperature (B) is displayed.

→ Make sure that the lens of the infrared sensor is clean. Dust, smoke or fluff on the lens may distort the results.

• The temperature display range (A) shows the measurement value in the selected unit. The displayed measurement value corresponds to the average surface temperature of the IR-measuring spot.
• After releasing the trigger (1), the last measured value will be displayed continuously in the display. The measurement value is frozen, in order to avoid fluctuation. "HOLD" (E) will also be displayed. The current measurement process is completed.
  • To locate hot or cold spots on the measured object, sweep along the object in broad strokes back and forth or up and down whilst you pull the entire object laterally. Observe the measurements whilst doing so. The laser beam indicates the measured area.
• When you release the trigger, the thermometer turns off automatically after 10 seconds if no other buttons are pressed.
• "Hi" will be displayed if the temperature exceeds the measuring range (>350 °C). "Lo" will be displayed if the temperature is lower than the measuring range (<-50 °C).

→ Longer measurements of high temperatures, with a close measuring distance, lead to heating of the measuring device itself and thus to inaccurate measurements. Adhere to the following rule in order to obtain exact measuring values: The higher the temperature the greater the measuring distance and the shorter the measuring time.

e) IR measuring spot size - distance-to-spot ratio (D/S)

• In order to obtain precise measuring results, the measured object must be larger than the IR measuring spot. The measured temperature is calculated using the average temperature of the measured area. The smaller the object, the closer it must be to the thermometer. It is also indicated on the thermometer. To ensure precise measurements, the measured object should be at least twice the size of the measuring spot.
• The exact size of the IR measuring spot is shown in the following diagram.
