● If the flow rate is very high and the flowmeter is reporting erroneous or unstable flow, then
the flowmeter may already be having trouble resolving the upstream and downstream
signals. In this event, it may be necessary to first lower the flow rate to a moderate level
before performing
the "Automatic" HF adjustment. Once this is done the flowmeter should
be able to properly measure the highest flow rates without problems.
● The limits of the "HF" parameter are +/- 0.7 and any attempt to manually install a larger
value will cause the flowmeter to abort the installation of the parameter.
Note
Pressing the <Left Arrow> at any stage prior to accepting the measured value will abort
the installation and return to the previous setting.
