Assigning Temperatures On The Basis Of The Scale - Bosch GTC600C Operating/Safety Instructions Manual

Make sure that a favorable measuring angle
is used on reflective surfaces in order to
ensure that the thermal radiation reflected
by other objects does not distort the result.
For example, the reflection of your own
body heat may interfere with the measure-
ment when measuring head-on from a per-
pendicular position. On a level surface, the
outline and temperature of your body could
therefore be displayed (reflected value), and
these values do not correspond to the actual
temperature of the measured surface (emit-
ted value or real value of the surface). Mea-
suring through transparent materials (e.g.
glass or transparent plastics) is fundamen-
tally not possible.
The accuracy and reliability of the measuring
results increase with better and more stable
measuring conditions.
Infrared temperature measurement is im-
paired by smoke, vapor/high air humidity or
dusty air.
Information for achieving improved measure-
ment accuracy:
• Get as close as possible to the measur-
ing object to minimize interfering factors
between you and the surface to be
measured.
• Ventilate indoor areas prior to mea-
surement, especially when the air is
contaminated or extremely steamy. After
ventilating, allow the room to acclima-
tize for a while until the usual tempera-
ture has been reached again.
Assigning Temperatures on the
Basis of the Scale
(Fig. 1, Fig. 6)
A Color Scale 36 is shown on the right-hand
side of the display. The values at the top and
bottom end are oriented to the Maximum
Temperature 35 and Minimum Temperature
37 recorded in the thermal image. For the
scale, 99.9% of the total pixels are evaluat-
ed. Colors are assigned to temperature val-
ues with a uniform distribution in the image
(linearly).
Different shades can therefore be used to
assign temperatures within these two limit
values. For example, a temperature that is
exactly between the maximum and minimum
value is assigned to the centre color range
of the scale.
Operation
To determine
ture of a specific area, move
the measuring tool so that the
Crosshairs with Temperature
Indicator 40 are aimed at the
required point or area. In the
automatic setting, the color
spectrum of the scale is always
distributed linearly (= uniform-
ly) across the entire measuring
range between the maximum
and minimum temperatures.
The measuring tool displays all
measured temperatures in the
measuring range in relation to
one another. If heat is displayed
as blue in the color palette in
an area, for example in a color
representation, this means that the blue ar-
eas are among the colder measured values
in the current measuring range. However,
these areas may still be in a temperature
range which could cause injuries in certain
circumstances. You should therefore always
note the temperatures displayed on the
scale or at the crosshairs themselves.
