INFORMATION
The re-measuring of the temperature only provides reliable infor-
mation when calibrated measuring tools are used and only if they
are used at points specified by INFORS HT. A measurement at un-
defined positions in the casing will not produce any usable data.
For information about temperature measuring, contact your local
INFORS HT representative or request a quote for calibrating the pa-
rameters.
