Slope Calibration – Reference Sections
This method of slope calibration is a development of the matched sections
discussed above. The user is required to enter the distance values for two fibre
sections but now each section can be at a different temperature. The user can
select two methods for defining what the temperature of each section is:
•
Select ‘Temperature source’ to be fixed. In this case the user enters the
temperature of each section into the ‘fixed temperature’ field.
•
Select ‘Measured T1/T2’ as the source. The software will now assume that
the external PT100 probe supplied is positioned within the section of fibre
specified and calculate the slope calibration appropriately.
NOTE: Again, the actual temperature values of the DTS trace may not be correct. It
is only important that the slope is corrected for at this stage.
Please see Figure 42 as an example of this setting.
