Measurement
Start the measurement as usual.
If no heat flow coefficients are available for the selected fluid, an error message will be
displayed.
Both temperature inputs are checked and the measured temperatures are displayed.
Press ENTER.
If a temperature cannot be measured (the temperature probe is not connected or is de-
fective), the error message
?UNDEF
will be displayed.
If
Fixed input val.
is selected during the configuration of the temperature input, the
temperature input (
Ts
) or the return temperature (
Tr
) have to be entered now.
For simulations, it is possible to enter both the supply and return temperatures as con-
stants. In this case, do not connect the temperature probes to the transmitter.
• Enter the fluid temperature.
• Press ENTER.
The measured heat flow (in BTU mode
Thermal energy
) is displayed.
