Fct. 2.9 Diagnose
↑ Fct. 2.9.1
This displays the temperature of the measuring tube.
By pressing the → key, the temperature will be indicated.
By pressing the ↵ key, you will be returned to the Function display.
↑ Fct. 2.9.2 Strain M. T.
This displays the strain value of the measuring tube stain gauge in ohms (where fitted).
↑ Fct. 2.9.3 Strain I. C.
This displays the strain value of the inner cylinder strain gauge in ohms (where fitted).
↑ Fct. 2.9.4 Tube Freq.
This displays the current resonant frequency of the sensor. This value is primarily used to
calculate the density of the process fluid.
↑ Fct. 2.9.5 Drive energy
This value indicates the current to the driver in percent. The heavier the fluid, the higher the
number. Air entrainment also shows up as a higher number.
↑ Fct. 2.9.6 Sensor A
↑ Fct. 2.9.7 Sensor B
These display the sensor signal level. Should be as per Menu 5.2.4, and be within 2% of
each other.
↑ Fct. 2.9.8 Comm.Errors
This displays the number of serial communication errors between the Front End (sensor
mounted) and the converter electronics since power up. Normally displays 0
