Preparation: First, the parameters emissivity slope, emissivity of channel 1 and channel 2, transmit-
tance and spot size filling should be set to 100%, as well as switch off the maximum value storage
and set the response time to 5-10 ms.
- Next: Move the sliders one by one:
- Base signal: Move until the higher value
of C1 or C2 has reached the target tem-
perature.
-
tion of the so-called dark-offset, a meas-
urement with completely darkened optics
is carried out, which can increase the ac-
curacy outside the adjusted temperature:
Cover the lens opaque (for example, press
the hand in front of the optics) and keep it
covered during the operation (takes up to
20 seconds).
- C1 or C2: Then readjust the other channel (C1 or C2) to the target temperature. When deter-
mining the dark-offset, under circumstances the values of C1 or C2 can be slightly misaligned.
In this case C1 and C2 must are readjusted to the desired value. Deviates the temperature after
dark offset by several degrees, this indicates the lens was not darkened 100% and ambient light
has penetrated. Then repeat the step.
- 2C: Finally, adjust the 2-color temperature until the temperature value of the calibration source
is shown correctly.

for example the calibration source does not work smoothly, nevertheless calibration values are
