3.3 Other screen elements:
3.3.1
Battery display:
This display informs about the charging status of the battery. A fully charged battery is displayed entirely
green (4 bars). 2 yellow bars are displayed from about half of battery run-time onward. A red bar is displayed
for the last quarter of battery run-time. Before the system shuts down, the battery symbol is blinking at least
for the past 5 remaining minutes.
3.3.2
Shutter Symbol:
The shutter is an important mechanical component of the camera, and is needed for recalibration of the
sensor. Upon recalibration, a short interruption of the display for less than 1 second is generated, in which
a green square is displayed in the upper left screen corner, and a low clicking can potentially be heard.
3.3.3
Overheat Warning (blinking)
Warning against high temperature in the infrared sensor. The camera does not switch off automatically. It
is highly recommended, though to put the camera in cooler areas immediately when this symbol appears.
Otherwise the camera can be irreversibly damaged.
3.3.4
Zoom
The zoom function is displayed by showing 2X or 4X at the left edge of the display.
3.3.5
Laser pointer
The laser pointer is activated or deactivated by pushing the round grey button
for >2 seconds. In
any case it will be deactivated automatically after 30 seconds. If the laser is active it is displayed by a green
star at the left edge of the display.
3.3.6
Temperature “measurement point” – Hot Spot
The Hot Spot allows reading out temperature information of objects. The sensitive measurement point in
the middle of the screen for this purpose is therefore to be directed on to the object.
A fixed emission coefficient of
ε
=0.97 is set in the factory. Actual temperatures may differ depending to the
density of the material, its surface composition, and distance from the measurement object.
3.3.7
Digital temperature
The temperature read out in the measurement point is displayed as a digital value in the lower right corner
of the image, starting a few seconds after the live image is displayed. This corresponds to temperature
measured by the Hot Spot in the middle of the screen. Please note that real temperatures can differ from
indicated temperatures due to various thermal emissivity of objects.
3.3.8
Temperature bar
The temperature bar is the graphical display of the temperature read out in the hot spot. A temperature bar
with 5 color levels is additionally displayed for the color schemes FIRE/STD and INV. Temperature values
are displayed in the respective mode to the left near the bar.
