IMPORTANT SAFETY INSTRUCTIONS

Read these instructions carefully and retain them for future use. If this product is passed to a third party, then these instructions must be included.

When using electrical appliances, basic safety precautions should always be followed to reduce the risk of fire, electric shock, and/or injury to persons including the following:

The safety features of this product may not protect the user if not used in accordance with this user manual.

• This product must be used by trained users only.
• Do not use if the product appears damaged or if it is not working properly. If in doubt, replace the product.
• Do not attempt repairs. There are no user serviceable parts.
• Do not deactivate safety systems and remove explanatory and hazard labels.
• Do not use meter around explosive gases, vapors, or in damp or wet environments.
• Never aim a laser beam at any aircraft. The laser beam can distract or flash blind pilots. The laser beam continues to travel even if the light is no longer visible.
• Ensure adequate safeguards, for example reflective safety vest, at the surveying site (e.g. when measuring on roads, construction sites, etc.).
• Store the product out of reach of children.

Laser Warnings

Risk of injury! Looking directly into the beam with optical aids (e.g. binoculars, telescopes) can be hazardous.

Risk of injury! Never look into the laser beam and never point it at people or animals. Laser radiation can seriously damage your eyes.

If operation settings or procedures other than those described in these instructions are used, it could lead to exposure to dangerous radiation.

• This device produces a visible laser beam which is emitted from the front of the product.
• Do not stare into the laser beam or direct it towards other people.
• Blinding by laser radiation can indirectly lead to serious accidents, especially for people who are driving a vehicle or operating machinery.
• 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.

Battery Warnings

• Exhausted batteries should be immediately removed from product and properly disposed.
• Keep batteries out of the reach of children.
• Do not dispose of batteries in fire.
• Remove batteries from product if it is not to be used for an extended period of time.
• If the battery leaks, avoid contact with skin and eyes. Rinse affected areas immediately with plenty of clean water, then consult a doctor.

Explanation of Symbols

The signal word that indicates a hazard with a low level of risk which, if not avoided, could result in minor or moderate injury.

Indicates a practical tip, advice or practice not related to personal injury.

This symbol stands for “Conformite Europeenne”, which means “Conformity with EU-directives”. With the CE marking the manufacturer confirms that this product complies with applicable European directives and regulations.

Intended Use

• The product is designed for use as a non-contact temperature measurements up to 1400 °F (760 °C).
• The product measures the surface temperature only. It does not measure the internal temperature of an object.
• The temperature is measured by using infrared radiation (IR) and scanning the infrared energy an object emits.
• The product is especially suited for measuring the temperature of hot, difficult to reach or moving objects.
• The product cannot measure through transparent surfaces, for example glass or water).

This product is not a substitute for professional medical advice, diagnosis or treatment.

Changing Batteries

Replace the batteries when the symbol is shown on the display.

• Open the battery compartment cover and remove the battery.
• Replace the battery with a new 9 V battery and close the battery compartment cover.

Operation

• Hold the product by its handle grip and point it toward the surface to be measured.
• Press and hold the trigger to switch the product on and begin measuring the surface temperature. The SCAN indicator is shown on the display. The temperature shown is updated continuously.
• Release the trigger. The indicator and the last measured temperature are shown on the display.
  The product automatically powers off after approximately 1 0 seconds of inactivity.

Settings

Press and hold the MODE button to enter settings menu. The  indicator flashes on the display. Press the MODE button repeatedly to toggle between 3 available settings:

Emissivity value

Press the ▲ and ▼ buttons to change the emissivity value between 0.10 and 1.00.

°C / °F unit

Press the ▲ and ▼ buttons to change the unit between Fahrenheit and Celsius.

High and low temperate alarm

• Press the ▲ or ▼ buttons to switch the high (H) temperate alarm on and off. To confirm press MODE button.
• Press the ▲ and ▼ buttons again to set the high (H) temperate value. Press and hold the ▲ and ▼ buttons to change the values faster. To confirm press MODE button.
• Press the ▲ and ▼ buttons to switch the low (L) temperate alarm on and off. To confirm press MODE button.
• Press the ▲ and ▼ again to set the low (L) temperate value. To confirm press MODE button.

Switching laser on/off

• To switch the laser on, press the button. The indicator is shown on the display once the laser is on.
• To switch the laser off, press the button again. The indicator goes off.

Viewing measured data

To display maximum temperature, minimum temperature, temperature difference or average temperature, press the MODE button repeatedly.

Field of View

• The meter’s field of view is 12: 1 . This means that if the product is 12 inches (30.5 cm) from the target, the diameter of the object under test must be at least 1 inch (2 .5 cm). Make sure that the target is larger than the unit’s spot size. The smaller the target, the closer you should be to it. When accuracy is critical, make sure the target is at least twice as large as the spot size.
• The measurements should normally be made less than 2 feet (60 cm) from the target.
• Steam, dust, smoke, etc. can cause inaccurate measurements.
• To find a hot spot, aim the meter outside the area of interest then scan across (in an up and down motion) until the hot spot is located.

Distance and Spot Size

Emissivity

• Most organic materials and painted or oxidized surfaces have an emissivity of 0.95.
• Inaccurate readings might occur while measuring shiny or polished metal surfaces. To compensate for this, cover the surface to be measured with masking tape or flat black paint.
• Measure taped or painted surfaces when the tape or painted surface reaches the same temperature as the material underneath.

Emissivity Values

During cleaning do not immerse the product in water or other liquids. Never hold the product under running water.

Cleaning the lens

• Blow off any debris using clean compressed air.
• Gently brush remaining debris away with a moist cotton swab. The cotton swab may be moistened with water.
