To clear a previously programmed linearizer table, enter the linearizer table
and change Point 1 Freq. to zero (0). After pressing the ENTER button, the
MX 9000 will display a warning that all table values will be cleared. If this is
correct, press the YES button. This will cause all table values to be set to zero
and 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
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.
