Scale Units (UNITS)
Enter the units associated with the desired pulse input rate scale values. Selecting the pulse input rate
scale units allows the meter to perform automatic unit conversions.
Note: This is not the rate display unit. Entering this unit defines the scaling only. For example, a flowmeter
may output 0 Hz at 0 gallons per minute, and 1000 Hz at 250 gallons per minute. In this case, the scale
units would be entered as gallons at a time base or minutes. However, the rate display units are chosen
in Pulse Rate Display Setup (Rate) on page 50. This allows for the Rate Units menu to be used to
automatically change the rate display to accurately display any rate unit desired.
Pulse Input Time Base (T BASE)
This is the time component pulse rate input scaling engineering unit. 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.
Scale Point Entry (INP, DSP)
Enter the pulse rate frequency in pulses per second (Hz) for each of the scale points (INP 1-32). After
each frequency input, enter the value in engineering units that corresponds to that input frequency. Up to
32 points may be programmed, as determined by the Number of Points (NO PTS) parameter.
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.
Save Scaling Points (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.
Calibrating the Pulse Rate Input (Cal)
The Cal menu is used to calibrate the pulse rate input using a live signal source to display the pulse input
in engineering units.
To access the Cal menu it is necessary to enable it using the Custom menu.
Total Reset (T RESET)
This menu is used to select the ways the total and grand total may be reset.
