9.1 Zero Displacement
A zero displacement can be carried out for the measured value:
value displayed = value measured - offset
Standard setting: 'off' = 0.0°, i.e. no zero displacement will be carried out. Together
with the scale correction (see below) this factor is mainly used to compensate for
sensor deviations. Input is in the display unit.
9.2 Scale Correction
This setting influences the scale of the measuring (factor is in %):
displayed value = measured value * (1+Scal/100)
Standard setting: 'off' =0.000, i.e. value is not corrected. Together with the zero
displacement (see above) this factor is mainly used to compensate for sensor
deviations.
9.3 Correction for surface measuring
The correction value refers to the temperature difference between the device- /
ambient temperature and the temperature determined by the thermocouple.
display = device tempe (measured temperature – device temperature) * Corr
Standard setting: ’off’ =1.000
This factor is used to compensate for losses of transfer in case of surface
measurements, occurring if the object to be measured is extremely hot but will be
cooled by lower ambient temperatures. The same can be true for sensors with a large
mass. Unless ’off’ is set, this value will be displayed shortly after the device is
switched on; during operation it will be identified by means of the Corr-arrow in the
display
9.4 Calibration Services
Calibration certificates – DKD-certificates – other certificates:
If device should be certificated for its accuracy, it is the best solution to return it to the
manufacturer.
Only the manufacturer is capable to do efficient recalibration if necessary to get
results of highest accuracy!
