17.2.4.2 Activation of Other Inputs
Inputs have to be activated if the measured values are to be displayed, stored and/or transmitted together with the other
measured values.
17.2.5 Temperature Correction
A temperature correction value (offset) can be set for each temperature input. If a correction value has been defined, it will
be added automatically to the measured temperature. This function is useful if, e.g.:
• the characteristic curves of the two temperature probes differ considerably from each other.
• a known and constant temperature gradient exists between the measured temperature and the actual temperature.
17.2.5.1 Activation/Deactivation the Temperature Correction
The temperature correction can be activated/deactivated in program branch

17.2.5.2 Input of the Temperature Correction
During the flow transducer positioning, the correction values will be requested for each input which has been activated and
where the temperature can be measured.
Attention! Observe the correct polarity to avoid damaging the current source. A permanent short circuit can lead
to the destruction of the current input.
In the program branch
Output Options
, select the channel for which an input is to be ac-
tivated.
The inputs assigned to the channel will be displayed one after another. Select
yes
for the
inputs that are to be activated.
Note! The total number of measured values that can be stored will be reduced if an input is activated.
Select
on
to activate the temperature correction,
off
to deactivate it.
Note! If
off
is selected, the temperature correction will be deactivated for all inputs. However, the entered
correction values for each temperature input will be stored and displayed again when the tempera-
ture correction is activated again.
Enter the offset for the temperature input.
Press ENTER.
Note! Only measured temperatures can be corrected.
In order to adjust the zero point, the same reference temperature is measured with the two tempera-
ture probes. The difference between the two measured temperatures is entered as the offset for one
of the temperature inputs. The difference can also be distributed between the offsets of the two chan-
nels.
The display of the temperature difference T1-T2 does not indicate if one or both temperatures are
constant or if the values have been corrected.
During the measurement, a corrected temperature value is marked by
