SAFETY INSTRUCTIONS

IMPORTANT:
Always follow these instructions. Failure to do so can result in dangerous exposure to laser radiation.

• Never look directly at the laser beam.
• Never point the laser beam at reflective surfaces, people, or animals. Even low-power laser beams can injure the eyes.
• Never open the laser module.
• Never modify the product in any way, for example, to increase the power of the laser beam.
• The manufacturer cannot accept liability for any personal injury and/or material damage resulting from failure to follow these safety instructions.

SAFETY INSTRUCTIONS FOR BATTERIES

• If a battery is inserted in an electrical product when the power switch is switched on there is a risk of personal injury and/or material damage.
• Incorrect use of the product can result in battery leakage. Avoid contact with battery fluid. On contact with battery fluid, rinse immediately with plenty of fresh water. If you get battery fluid in your eyes, rinse your eyes with clean water for at least 10 minutes and then seek medical attention immediately.
• Battery fluid can cause skin irritation and/ or burns.
• Do not expose batteries to heat, direct sunlight, naked flames, etc.
• Never attempt to charge batteries that are not rechargeable – the risk of explosion.
• Store batteries out of the reach of children and pets. Never short-circuit batteries, or attempt to open or dismantle batteries.
• Seek medical attention immediately if anyone has swallowed a battery.
• If necessary, clean the battery terminals and product terminals before inserting new batteries.
• Insert the batteries with the correct polarity.
• Remove discharged batteries from the product at once, otherwise, there is a risk of battery leakage.
• Replace all the batteries at the same time.
• Only use batteries of the recommended type – do not mix different types of batteries, or new and old batteries.
• Check that the product is switched off before putting it away after use.
• Remove the batteries if the product is not going to be used for some time.

USE

Basic IR measuring

1. Hold the IR thermometer with the handle and point it at the surface to be measured.
2. Press the button to start measuring. The SCAN symbol flashes and the sensed temperature and temperature unit are shown.
3. Release the button. The HOLD symbol is shown on the display and the last sensed temperature is “frozen” on the display for about 10 seconds. The product then switches off automatically.

LASER INDICATOR
Press the laser indicator button to switch on the laser indicator. Press the button again to switch off the laser indicator.

BACKLIGHT
The backlight goes on when the backlight button is pressed (the product must be switched on). Press the button again to switch off the backlight.

NOTE:
Prolonged use of the backlight reduces the battery life.

INDICATION OF VALUE OUTSIDE THE MEASURING RANGE
The code ERR will be shown instead of a temperature value if the sensed temperature is over or below the measuring range.

FIELD OF VISION
The product has a field of vision ratio of 12:1, which means that a target 1 dm long can be measured at a distance of no more than 12 dm. Other distances are shown in the diagram below. The distance for the measuring should normally be kept as short as possible. The product can also be used for measuring at medium-range distances, but in such cases, the measuring can be affected by external sources of light. At long distances, the measurement point can also become so large that it also includes surfaces where the temperature is not supposed to be measured.
FIG. 3

TEMPERATURE MEASURING

• The object to be measured must be larger than the size of the measurement point at the measurement distance, see the field of vision diagram in these instructions or on the side of the product.
• Remove any crusts of ice, oil, or other impurities from the surface where the temperature is to be measured before measuring it.
• If the surface of the object is highly reflective, apply masking tape or dull black paint to the surface before measuring. Allow the tape or paint to acquire the same temperature as the surface of the object before measuring.
• The temperature of objects behind glass or other similar transparent materials cannot be measured with the product. In such cases, the product will only measure the temperature of the glass surface.
• Steam, dust, and smoke, etc. can conceal the object to be measured and produce incorrect values.
• The product compensates automatically for temperature deviations resulting from the ambient temperature. It can, however, take up to 30 minutes for the product to adjust if the deviations are significant.
• To locate a hot point, aim the product at a point outside the target area and then sweep slowly forward and back over the target area.

Continuous sensing
Continuous sensing is possible.
Emissivity: 0.95, response time: 500 ms

Reading
Precision
Precision: 0 to 320°C ±2°C or ±1.5% of indicated value –50 to 0°C ±3°C.
Resolution
0.1 °C/°F.
Field of vision ratio
The ratio between distance D and measuring point diameter S is approx. 12:1. Approx. 90% of the thermal energy is focused on the measurement point.

EMISSIVITY AND IR MEASUREMENT THEORY
An infrared thermometer measures the surface temperature of the measurement object. The optics and detector in the thermometer detect emitted and reflected infrared radiation, interpret the detected radiation and show it on the display as a temperature value. The amount of infrared energy emitted by an object is proportional to the temperature and emissivity of the object. Emissivity is a measurement of the capacity of a surface to release radiation, and depends on what materials the surface consists of and how smooth and reflective the surface is. The emissivity for a completely dull black surface is 1.00 but can be as low as 0.1 for very bright and highly reflective surfaces. Model DV-2013LT is set for an emissivity of 0.95, which gives a correct measurement in about 90% of all normal cases of IR temperature measurements.

MAINTENANCE

REPLACING THE BATTERY
When the symbol for the discharged battery is shown on the display the 9 V battery in the product should be replaced. The battery compartment is located under the measurement button on the product. The battery cover can be carefully prized up near the measurement button and folded down as shown in the diagram. Replace the 9 V battery and close the battery cover.
