YPP6830 Explosion-Proof Pulse Input Rate/Totalizer
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 entered. 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 linearization 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)
•
After entering the last display value,
Save (save?)
the calibration 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 and 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.
