3. To exit Force Transmit, press the <Left Arrow> and a [Detection Fault] prompt will appear (see
above). Press the <Left Arrow> again and the meter will return to the Pick/Install Xdcr menu and
highlight the [Empty Pipe Set] menu cell.
4. To force a frequency , repeat steps 1 and 2 above, but press <Right Arrow>. The following
typical display line will appear:
Using numeric keys enter the frequency and press <ENT>.
5. If the Force Transmit diagnostic procedure is not used , the normal [Install Complete?] func-
tion occurs as follows:
To complete the Install process after mounting the transducers press <ENT>.
Immediately after you press <ENT>, the computer starts an internal process called an Initial Makeup. The
current Initial Makeup activity, for example:
Drive 14 m 10 [—] appears at the top of display screen.
During the Initial Makeup, the flowmeter verifies your site data, records the sonic characteristics of the
pipe and liquid and then adjusts internal parameters to optimize flow measurement. Please remain
patient. This process can take several seconds or several minutes to complete. There is no relationship
between the length of an Initial Makeup and the meter’s subsequent performance. An Initial Makeup for
larger pipes (and more demanding application conditions) simply takes a little longer. Upon successful
completion of the initial makeup, the FUH1010PVX will show the measured Vs on the top prompt line as
shown below.
This means that the flow computer was able to complete the Initial Makeup and is now actively measur-
ing flow. This pop-up window allows you to “fine-tune” the Measured Vs by pressing the <Right Arrow> to
activate numeric entry. You can then use the numeric keys or Magnetic Wand to type a different value.
However, only edit the Measured Vs when you are certain of your liquids actual sonic velocity. If, how-
ever, there is a large discrepancy between the “measured” Vs and the “actual” Vs, then consider that an
accurate Vs measurement depends on certain parameters that the flow computer cannot sense directly
(e.g., pipe dimensions or transducer placement). In other words, entering incorrect pipe parameters or
not using the recommended spacing could result in an erroneous Vs measurement.
