Section 2
Using the [HF] Menu Item
Two methods for adjusting this parameter are provided via the [HF] menu cell, located within
the “Diagnostics / Site Setup” submenu. The “Manual” method provides direct entry of this
parameter and is primarily intended for the advanced user, whereas the “Automatic” method
allows the 1010 flowmeter to automatically measure the required correction and install the
parameter.
Guidelines for using the [HF] menu item are described below:
l This menu is only accessible for the transducer channels, not the virtual (average flow)
channel of the flowmeter. (i.e., Diagnostics Path 1 or Path 2, but not Path 1 & 2).
l The 1010 flowmeter will inhibit the “Automatic” installation of the [HF] parameter if
the flow rate is insufficient (too low) to accurately measure the required correction. If
the maximum flow rate for the application is relatively low then this correction should
not be required.
l 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.
l 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.
To access this [HF] menu item proceed as follows:
l At the [Meter Type] Menu, press the <Right Arrow> and then <ENT> to select the
desired Path (e.g., Dual Path Flow).
l In the [Dual Path Flow] Menu, press the <Down Arrow> and scroll to the [Diagnostic
Data] menu cell. Press the <Right Arrow> to select it.
