4.10 Density
Numeric entry
When the flowrate indication and the totalization are to be in
mass units, g, kg, t pounds or uton, a fixed density value can be
entered for the calculations.The conversion to mass flowrate
can be set in the range from 0.01 to 5.00000 g/cm
Density
2.54300
4.11 System Zero
Numeric entries
After the installation has been completed the zero should be ad-
justed at the converter. The flowrate is to be reduced to zero.
The adjustment can be made automatically by the converter. A
manual entry is also possible. The zero value is set to 0 Hz
when the C/CE key is pressed. A measured output frequency
value can then be entered as the correction value.
Select the parameter "System Zero" and press ENTER.
For security the following message is displayed:
System Zero
3.5 Hz
The choice between "manual" and "automatic" can be made
using the STEP or DATA keys.
The converter initiates the automatic adjustment procedure
when ENTER is pressed. The values in the display count down
from 255 to 0. The adjustment procedure is repeated 4 times.
The final zero value must be within the limits set in the converter
of ± 50 Hz. If the value is outside of the limits the zero
adjustment is not completed. The value determined by the
converter is displayed in the 2nd line.
