thermoIMAGER TIM 26
Note
In case that the emissivity and / or the ambient temperature values are controlled through the Process
Interface (PIF) the here defined values will be ignored (please also see 2.5).
The display of actual
values w
ill be shown in the status bar.
2.4.4. Reference Temperature
The detector of the thermoIMAGER has a thermal drift over the
time and must be corrected by self referencing. At applications
where a high measurement accuracy is needed, the thermal
image can be corrected permanently by setting a reference
temperature. Using the menu Tools, Configuration, Device
and Reference temperature several options for manual or
automatic correction can be set.
If there is an area within a thermal image having a constant temperature value (e.g. black body) the Source can
be defined as a Fixed value. By the option Compare with measuring area the area with constant
temperatures can be determined. The known reference value can be set within Fixed value. If the temperatures
are changing slightly within the defined area due to a thermal drift, the whole image will be corrected by a
certain factor.
Alternatively, the correction can be done by an external value (e.g. via connected pyrometer) by choosing the
process interface PIF in (please also see 2.5).
