Function group PARAMETER
Verification of the amplifier takes place along four measuring points MP1 to MP4. Use this function
group to enter the two selectable measuring points MP2 and MP3 (in % of the full scale value).
!
Note!
The value of MP1 is prespecified (5% of the full scale value MP4).

PARAMETER
FLOW 100% Use this function to display the full scale value of the verification flow.
In liquid applications, the 100% value usually corresponds to a fluid velocity of 8 m/s
and a velocity of 60 m/s in gas/steam applications.
MEAS. POINT 2/3 Use this function to enter the measuring points MP2 and MP3 (in % of the full scale
value).
User input:
MP2: 10 to 90 %
MP3: 15 to 95 %
!
Note!
• The value of MP2 must be less than the value of MP3.
• Both values are stored permanently.
• In demanding measuring applications, the usable measuring range of the vortex
measuring device can be restricted to such an extent that the lower MP1 verification
measuring point cannot achieve the 5% value. In this instance, the minimum which
can be achieved of the measurable flow is determined and calculated as a % value of
the maximum value MP 4 and displayed. MP2 and MP3 are then determined again
as default values and displayed. However, they are not saved when the work with
Fieldcheck is completed.
Factory setting:
MP2: 10 %
MP3: 50%
