Reference temperature mode
In reference temperature mode, 2 measured surface temper-
atures are compared and the difference is displayed. This
way, significant temperature differences can be measured at
2 different positions on one or more surfaces.
Press the measure button
(1)
to measure the reference value
(j)
. All subsequent measured values are then related to the
reference value
(j)
. The temperature difference
(k)
is dis-
played immediately after a new measurement. With each
new measurement, the measured value
(h)
is updated in the
area of the display with the white background and the differ-
ence from the reference value is recalculated.
If the new value
(h)
is more than 1 °C lower than the refer-
ence value
(j)
, the indicator light
(15)
lights up blue. If the new value
(h)
is more than
1 °C lower than the reference value
(j)
, the indicator light
(15)
lights up red. If the differ-
ence value
(k)
falls within the ±1 °C range, the indicator light
(15)
does not light up.
Thermal bridge mode (see figure B)
In thermal bridge mode, the surface and ambient temperat-
ures are measured and compared with each other. If there is
a significant difference between the two temperatures, a
thermal bridge (see "Thermal bridge", page 37) warning is
issued.
Press the measure button
(1)
and aim the laser circle so that
it is perpendicular to the centre of the object being meas-
ured. Once the measurement is complete, the measured sur-
face temperature
(h)
is displayed. The ambient temperature
(s)
is automatically displayed before the measurement is
taken.
The measuring tool automatically compares the values and interprets the result as fol-
lows:
Green
indicator LED
(15)
: Low temperature difference, no thermal bridges
present.
Yellow
indicator LED
(15)
: Temperature difference near the limit value, a
thermal bridge may be present in the area being measured; if necessary, re-
peat the measurement at a later point in time.
