 A click on "Start automatic adjustment" starts the proce-
dure.
Note: This will set the emissivity slope and the emissivity of
channel 1 and channel 2 to 1 (100%), will switch off the
peak picker and set the response time to 5 ms. These val-
ues are not automatically set back to their previously set
values and then have to be readjusted afterwards!
 Measurement with covered optics (only M3 models): At
the determination of the so-called dark-offset, a measure-
ment with completely darkened optics is carried out, this
can increase the accuracy outside the adjusted tempera-
ture: Cover the lens opaque (for example, press the hand
in front of the optics) and keep it covered during the opera-
tion. This takes up to 20 seconds, after completion, the but-
ton text changes to "Dark offset is determined".
 Remove the optics cover and confirm that the optics cov-
er is removed.
 "Determine adjustment values" continues the automatic
adjustment in front of the calibration source.
 Result: After finishing the adjustment of the success or
failure will be displayed in text form.
 A backup file can be created with the determined adjust-
ment values (adjustment value file). This can be used to write the values back into the device at any
time, for example, when the device has been reset to factory calibration.
 The calibration process takes between one and two minutes. If anything
goes wrong, for example the calibration source does not work smoothly, nevertheless calibration val-
ues are written into the pyrometer. In this case the process should be performed again or the device
should be reset to factory settings, this sets all calibration values back to factory calibration.
 Load adjustment value file loads adjustment values from a saved file into
the pyrometer.
 The single-point adjustment function also can be performed manually with
sliding controllers. In this case the numerical value of the adjustment can be observed.
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.
- M3 models:
Move the sliders one by one:
- Base signal: Move until the higher value
of C1 or C2 has reached the target tem-
perature.
- In the determina-
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
