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
diameteris12.5mm.However,keepsufcientdistancetoavoidfaultymeasurementdueto
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
themeasuringsurface(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
