Multi-Point Linearization (nopts)
Up to 32 linearization points can be selected under the nopts function. The multi-
point linearization can be used to linearize the display for non-linear inputs.
Number of Points (nopts)
Enter number of linearization points. The default value is 2 points. For linear inputs
requiring only 2 scale points, the number of points can be left at 2.
Scale Units (SCALE UNITS)
Enter the units associated with the desired scale values. Selecting the scale display
units allows the meter to perform automatic unit conversions.
Pulse Input Time Unit (Time UNIT)
This is the time component for the engineering units of the display values being en-
tered. Enter the appropriate units/second, units/minute, units/hour, or units/day that
corresponds to the values being entered at the display 1-32 ( dsp) menus.
For example, if the display values are being entered in gallons/second the time unit
would be set to seconds.
Scale Input and Display (INPUT, DSPLY)
Each scale input point is defined by an input frequency and a corresponding display
value.
The frequency inputs may be entered with up to three decimal places. To access the
decimal location digits when entering a frequency, use the Right button to scroll to
the three decimal location digits.
Manual Multi-point Entry (INP, DSP)
Manual entry of the linearization data is done once the number of points has been
selected (NO PTS). Input signal levels (InP 1-32) for up to 32 points, along with the
desired/corresponding meter reading (dSP 1-32), should be entered for each lineari-
zation point.
Each scale point (1-32) has an input value and a display value. The input value is the
number of pulses/sec (frequency), and the display value is the corresponding display
value for that input in the time unit selected (example: gallons per minute, or GAL/M)
Important Programming Note: Save (save?)
After entering the last display value, the scaling entries must be saved (SAUE?)
before they will be put into effect. However, you may move past this selection
using the Up arrow key if you need to go back and correct an earlier entry. Once
confident in the entries, however, the user must navigate back to the Save menu
screen (SAUE?) and press the Enter key to save the changes.
