INFORMATION
Re-measuring the temperature only provides reliable information
when using calibrated measuring tools, and only if they are used
at points specified by INFORS HT. Measurements taken at unde-
fined points 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
parameters.
