To set the functions of temperature measurement.
Notice: Standard range: -200 to 230°C
High temp. range (/HT): 0 to 400°C
Select:
Select:
(low range value)
Set a temperature value to the 4 mA or 0 Hz
(upper range value)
Set a temperature value to the 20 mA or xxxxx Hz.
Abs(URV-LRV) ≥ 10K
Set the in s. Damping time affects outputs and display.
After 5 times damping time the given value is displayed (t=63%).

Restrictions:
All alarms have to be in 0-110%
of URV-LRV Alarm criteria 2
must always be larger than alarm
criteria 1.

What happens in case of an alarm has to be dened in Status out (7.12,
7.13).
Select:
Select a temperature value in case of malfunction of the built in
temperature sensor.
The ROTAMASS temperature sensor is installed outside of the measuring
tubes. So at high or low uid temperature the temperature measurement
may show a deviation as a function of the quality of heat insulation. This
function allows correcting temperature measurement for better accuracy
in mass ow and density.
Note: It is not recommended to use this function unless correct
measurement over the complete process temperature range can be
conrmed. It is not sufcient to proof correct measurement at one
temperature or in a very narrow temperature range unless the process
operates exclusively within this range.
To set the function of the medium velocity.
Not available for gas measurement (/GA)
