10.6 Problems with the totalizers
The values of the totalizers are too high.
See Special Funct.\SYSTEM settings\Measuring\Quantity recall . If this menu item is activated, the values
of the totalizers will be stored. The totalizers will continue with these values at the start of the next measurement.
The values of the totalizers are too small.
One of the totalizers has reached the upper limit and has to be reset to zero manually.
The sum of the totalizers is not correct.
See Special Funct.\SYSTEM settings\Measuring\Quant. wrapping . The sum of both totalizers (throughput)
transmitted via the output is no longer valid after the first overflow (wrapping) of one of the totalizers.
10.7 Problems during the thermal energy rate measurement
The measured fluid temperatures differ from the actual values.
The temperature probes are not sufficiently insulated.
On a pipe with a small diameter, the temperature probe is lifted from the pipe surface by the insulation foam.
The measured absolute value of the thermal energy rate is correct but has the opposite sign.
Check the assignment of the supply and return temperature to the temperature inputs.
The calculated thermal energy rate differs from the actual one although the measured flow and temperature
values are correct.
Check the thermal energy rate coefficients of the fluid.
