the Linearizer will be turned OFF. The user has the ability to press NO button to cancel this option and
return to Point 1 programming screen.
Changing the linearizer table
To change a table Point value, enter the programming screen and press the ENTER button to get to the
table value to change. After changing the relevant values, continue pressing the ENTER button through
the remaining table values until reaching the end of the programmed table (first table point whose Freq.
is zero) to exit the table.
Adding linearizer table point
To add more table points, it must be noted that data can only be added to the end of a table. Therefore,
if the additional point(s) to add do not have a frequency greater than the last entered point, it will
require the user to manually “shift” the table points by entering the new points after the next smallest
existing value and then re-entering the remaining points.
If an existing table is changed and has more points than required, once the required points have been
entered and the next table value has the Freq. changed to zero, all remaining points will automatically
be reset to zero when exiting the table.
Quadrature Signal Programming
Figure 25: Quadrature Signal Programming
When used with two inputs on the same meter, the MX 9000 can display the flow direction if the signals
are 90° out of phase, due to the quadrature nature of the signals available on gear meters.
Enabling the quadrature signal display will automatically disable all screens associated with channel B as
it is required that when using quadrature signals it can only be with one flow meter.
System Settings Programming
