9. Inserting/changing the battery

→ Replace the battery when the low-battery symbol appears on the display.

- Loosen the screw using a Phillips screwdriver. Remove the battery compartment cover.

• Remove the flat battery from the battery clip and connect a new battery of the same type with the correct polarity to the battery clip.
  The battery clip is constructed so the battery can be connected only with the correct polarity. Do not use force when plugging in the battery.
• Replace the cover of the battery compartment again and secure it with the previously loosened screw.

10. Operation

a) Function

• Infrared thermometers measure the surface temperature of an object. The sensor of the device analyses the emitted and reflected heat radiation of the object measured, and converts this information into a temperature value.
• Emissivity is used to describe the energy emission characteristics of a material. The higher the emission level, 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. For this reason, the emission level can be set.

b) Measuring

• Point the measuring hole, preferably at a 90° angle, at the object to be measured. Make sure the object to be measured is not smaller than the IR measuring spot of the device.
• Press and hold the measuring button. The measuring value is indicated on the display. The displayed measurement value corresponds to the average surface temperature of the IR measuring spot. During measurement, the SCAN indicator is shown on the display.
• After releasing the measuring button, the last measured value will be displayed for approx. 8 seconds for improved readability. The HOLD indicator also appears.
• About 8 seconds after releasing the measuring button, the device turns off automatically.
  • Horizontal bars appear on the display if the temperature range is exceeded.

To determine the hottest spot on the measured object you have to scan the object, with the measuring button held down, in a zigzag motion until you find the hottest spot. When the MAX temperature function is active, the highest measured temperature appears at the top of the display during measurement.

In order to obtain exact measured values, the infrared thermometer has to be adjusted to the ambient temperature. Allow the device to adjust to the ambient temperature after relocation.

Shiny surfaces affect the measured result. To compensate, the shiny part of the surface can be covered with adhesive tape or matt black paint.

The device cannot measure through transparent surfaces such as e.g. glass. Instead, it measures the surface temperature of the glass.

Prolonged measurement of high temperatures at near measuring distances leads to self-heating of the measuring device and thus to 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.

c) IR measuring spot size - Ratio measuring distance:measuring surface

• 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.
• The exact size of the measuring spot is shown in the following diagram. 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.

0.5in@12.5mm 1in@25mm 8in@200mm 16in@400mm Distance : Spot = 16:1 D S

The optimal measuring distance for this infrared thermometer is the focal point of both target lasers as this affords the greatest measuring accuracy. The size of the measuring spot at the focal point is 12.5 mm.

• The smallest measurement diameter is achieved up to a distance of 20 cm. The measurement diameter is 12.5 mm. However, keep sufficient distance to avoid faulty measurement due to heating of the IR thermometer.
  • Example: At a distance of 2 m, the measurement diameter is 125 mm.

d) Dual target laser

• The dual target laser can be activated and deactivated. Press and hold the backlight/laser button.
• When the laser is activate, the laser symbol appears on the display.
• Press the backlight/laser button again to deactivate the target laser. The laser symbol disappears.
• The target laser is constructed in dual design and marks the inner, approximate edge area of the measuring surface (approx. 90%).
• When both laser spots meet, the smallest measuring surface has been achieved. The latter has a diameter of 12.5 mm
• With larger distances, the two laser spots move apart, analogue to the measuring surface.

e) Backlight

When the device is on, press the backlight/laser button to turn the display backlight on/off.

f) Max., min., differential and average measuring function

• When the measuring button is released, the last measured value is frozen on the display. The standby indicator HOLD lights up on the display.
• Repeatedly press the MODE button. One of the following indicators and the associated measured value appears on the display:

MAX: the highest measured value of the last measurement

MIN: the lowest measured value of the last measurement

AVG: Average value of the last measurement

DIF: Difference between highest and lowest measured value of the last measurement

g) Bar graph

• The bar graph can be used to graphically display the current measured value in relation to the MIN/MAX values. The left end represents the MIN value of the current measurement, the right end the MAX value.
• Example: The MIN value is 0 °C and the MAX value +100 °C. The current measurement is +50 °C. In this case the bar graph deflects to the middle of the display.

11. Settings
