8 Storage and Output of Measured Values
8.7.1 Storage Mode
Select the storage mode (SAMPLE or AVERAGE).
Storage Mode
>SAMPLE< average
In SAMPLE mode, US300PM uses the momentary
measured value for storage and online output.
In AVERAGE mode, US300PM will use the calculated
mean of the measured values of a storage interval for
storage and online output.
Confirm your selection by pressing ENTER.
Further explanations
• The storage mode does not influence the continuously operating process interfaces (e.g. current
output).
• In AVERAGE mode, all primary measuring quantities are averaged.
• In case no mean value could be calculated over the complete storage interval while the unit was in
AVERAGE mode, the mean value for this interval will be marked as invalid. In the ASCII file with the
stored measured values, ´???´ will appear for invalid mean values and the associated quantity of
measurement. There will not be an indication of how many momentary measured values a valid
mean value consists of.
8.7.2 Storage of the Totalizer
It is possible to store the value of the currently displayed totalizer only or one value for each flow direction. This setting is cold-start resistant.
In the SPECIAL FUNCTION \ SYSTEM SETTINGS \ STORING program branch, select the QUANTITY STORAGE entry.
Quantity Storage
>ONE<
both
Select ONE if US300PM should only store the displayed
totalizer. Select BOTH to enable storage of the totalizer
value in function of the flow direction.
Confirm by pressing ENTER.
Further explanations
• US300PM will store the totalizers only if they are activated and the data logging function enabled.
• The storage of one totalizer halves the total number of measured values which can be internally
logged, the storage of both totalizers quarters it.
Example:
In the program branch SPECIAL FUNCTION, US300PM shows that 10,000 measured values can
still be stored. If the totalizers are activated and only one total value is logged, 3,333 data fields are
available for storage. If both total values are saved, 2,000 data storage operations can be made.
8.7.3 Storage of the Amplitude
In the SPECIAL FUNCTION \ SYSTEM SETTINGS \ STORING program branch, select STORE
AMPLITUDE entry.
Store Amplitude
off
>ON<
54
If you select ON, US300PM will store the amplitude of
the measured signal with the measured flow values
when the storage of the measured values is activated.
Confirm by pressing ENTER.
