The ratio between the dot and the
distance is 1:12. This means that the
distance between the thermometer and
object is 12 times greater than the diam-
eter of the dot.
If the laser dot has a diameter of 2.5 cm,
the distance is approximately 30 cm.
If you want to find the warmest spot
on a surface, hold the on/off button
pressed and move the thermometer up
and down across the surface until you
find the area with the highest temper-
ature.
If you want to measure a shiny surface,
it may be necessary to apply masking
tape to it first, or to paint it black to
avoid a reflection.
OTHER FUNCTIONS AND SETTINGS
Press the MODE button (3) one or more
times to change between the different
displays:
MAX The MAX (H) symbol is shown on
the display. The display shows the
highest measurement recorded.
MIN The MIN (I) symbol is shown on
the display. The display shows
the minimum measurement
recorded.
EMS The EMS (G) symbol is shown on
the display. The display shows the
emissive power value, which by
default is set to 0.95. This setting
is suitable for most painted sur-
faces and organic materials. Press
the laser and background lighting
button to change the value to 0.8.
CAL The CAL (F) symbol is shown on
the display. The display shows
the calibration value, which by
default is set to 0. You can change
this value by +/- 5 °C using the
buttons (2, 4).
Example: If the actual tempera-
ture is 25 °C, and the measure-
ment shows 26.3 °C, you can set
the calibration value to -1.3 °C.
Replacing the battery
When the battery low symbol (E)
appears on the display, replace the bat-
teries with 2 new equivalent 1.5 V AAA
batteries.
Remove the battery cover, take out the
used batteries and insert two new ones.
Please ensure that the poles are correct-
ly aligned.
Replace the battery cover.
Cleaning and maintenance
Clean the lens with compressed air
or an aerosol containing clean air. If
necessary, wipe the lens with a swab
dipped in distilled water.
Wipe the thermometer with a well-
wrung cloth after use, and always keep
all surfaces clean.
