Go into the "Sensor"
function of the
Diagnostic menu to
read the measured
fluid temperature
(chpt. 9.13.4).
→
If necessary, check
whether the built-in
Pt1000 is working
correctly by measuring
a fluid with a known
temperature,
→
If the Pt1000 is faulty,
return the device to
Bürkert,
→
If the Pt1000 is not the
cause of the problem,
check the process.
