• Measuring instruments don’t belong to children hands!

Cleaning the cabinet

Clean only with a damp soft cloth and a commercially available mild household cleanser. Ensure that no water gets inside the equipment to prevent possible shorts and damage to the equipment.

Laser classification

This device emits a visible laser beam of the Laser class 2 in accordance with EN 60825-1:2014, which emerges at the top of the unit. Use this device only in accordance with the relevant national standards.

• The device should only be handled with extreme caution, and avoid physical contact with the laser. (Laser emission)
• Never point the laser at people or animals and never look directly into the laser beam, since it can cause serious eye damage.
• Avoid the use of lasers at eye level and possible reflections off reflective surfaces such as glass and polished metal.
• Never aim the laser to gaseous substances or gas reservoirs. (Explosion hazard)
• Any use must be performed by qualified personnel only in compliance with the relevant national regulations.

Measurement Considerations

Holding the meter by its handle, point the IR sensor toward the object whose temperature is to be measured. The meter automatically compensates for temperature deviations from ambient temperature. Keep in mind that it will take up to 30 minutes to adjust to wide ambient temperature changes. When low temperatures are to be measured followed by high temperature measurements some time (several minutes) is required after the low (and before the high) temperature measurements are made. This is a result of the cooling process which must take place for the IR sensor.

Non-Contact IR Measurement Operation

Power ON/OFF

1. Press the ON/HOLD (8.) key to take a reading. Read the measured temperature on the LCD.
2. The meter powers OFF automatically approximately 7 seconds after the ON/HOLD key is released.

Selecting Temperature Units (°C/°F)

1. Select temperature units (degrees °C or °F) by first pressing the ON/HOLD (8.) key and then pressing the °C or °F key. The unit will be seen on the LCD.

Data Hold

• This meter automatically holds the last temperature reading on the LCD for 7 seconds after the ON/HOLD (8.) key is released.
• No extra key presses are necessary to freeze the displayed reading.

MIN/MAX- Function

1. To activate the minimum-value holding function, or the maximum-hold function, press ON/HOLD – button.
2. MIN/MAX – key until the desired setting appears in the display.
3. ON/HOLD – press to display a reading.

Backlite LCD

• Select backlite by first pressing the ON/HOLD (8.) key and then pressing the BACKLITE (6.) key. Press the backlight key again to turn the backlight OFF.

Laser Pointer

1. To turn the laser pointer ON, press the LASER (7.) key after pressing the ON/HOLD (8.) key.
2. Press the Laser key again to turn the laser OFF.

Desciption of the Laser Pointer

• D = Distance (avoid exposure-laser radiation is emitted from this aperture) approx. 12:1
• S = diameter of the spot center

So if the measurement object is e.g. 120cm away, the measurement surface will have a diameter of 10cm.

Inch to Centimeter

Please note:  The laser is only a guide line and is placed 16 mm above the Infrared-Sensor.

Emissivity: 0,95 fixed value
Field of view: 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, that the target is at least twice as large as the spot size.

How it Works

Infrared thermometers measure the surface temperature of an object. The unit’s optics sense emitted, reflected and transmitted energy, which is collected and focused onto a detector. The unit’s electronics translate the information into a temperature reading hich is displayed on the unit. In units with a laser, the laser is used for aiming purposes only.

Field of View

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.

Distance & Spot Size

As the distance (D) from the object increases, the spot size (S) of the area measured by the unit becomes larger. See Fig. 2

Locating a hot Spot

To find a hot spot aim the thermometer outside the area of interest, then scan across with an up and down motion until you locate hot spot.

Reminders

1. Not recommended for use in measuring shiny or polished metal surface (stainless steel, aloy, etc.) See emissivity.
2. The unit cannot measure through transparent surfaces such as glass. It will measure the surface temperature of the glass instead.
3. Steam, dust, smoke, etc. can prevent accurate measurement by obstructing the unit’s optics.

Emissivity

Most (90 % of typical applications) organic materials and painted or oxidised surfaces have an emissivity of 0,95 (pre-set in the unit). Inaccurate readings will result from measuring shiny or polished metal surfaces. To compensate, cove the surface to be measured with masking tape or flat black paint. Allow time for the tape to reach the same temperature as the material underneath it. Measure the temperature of the tape or painted surface.

Emissivity Values

Plaster| 0,80 to 0,90| Copper oxides| 0,78
Mortar| 0,89 to 0,91| Iron oxides| 0,78 to 0,82

Battery Replacement

A Bat Symbol in the display is the indication that the battery voltage has fallen into the critical region (6,5 to 7,5 V). Reliable readings can be obtained for several hours after the first appearance of the low battery indication. Open the battery compartment (see picture below) and remove the battery, then install a new battery and replace the cover.

ATTENTION: Batteries, which are used up dispose duly. Used up batteries are hazardous and must be given in the for this supposed collective container.

Notification about the Battery Regulation
The delivery of many devices includes batteries, which for example serve to operate the remote control. There also could be batteries or accumulators built into the device itself. In connection with the sale of these batteries or accumulators, we are obliged under the Battery Regulations to notify our customers of the following: Please dispose of old batteries at a council collection point or return them to a local shop at no cost. The disposal in domestic refuse is strictly forbidden according to the Battery Regulations. You can return used batteries obtained from us at no charge at the address on the last side in this manual or by posting with sufficient stamps. Contaminated batteries shall be marked with a symbol consisting of a crossed- out refuse bin and the chemical symbol (Cd, Hg or Pb) of the heavy metal which is responsible for the classification as pollutant:

1. “Cd” means cadmium.
2. “Hg” means mercury.
3. “Pb” stands for lead.
