Rate input settings
(continued)
Table 1-2:
Setting Description
Accuracy ±0.03% of calibrated span ±1 count
Temperature drift Rate display is not affected by changes in temperature.
Low-flow cutoff 0-99,999 (0 disables cutoff function)
Decimal point Up to four decimal places or none:
4.4444, 33.333, 222.22, 1111.1, or 00000
Calibration May be calibrated using K-Factor, scale without signal source, or by ap-
plying an external calibration signal.
K-Factor Field programmable K-Factor converts input pulses to rate in engineer-
ing units. May be programmed from 0.000001 to 9,999,999 pulses/unit.
Calibration range Input 1 signal must be ≥ 1 Hz; input 2 signal may be set anywhere above
input 1 setting.
Minimum input span is 1 Hz.
An Error message will appear if the input 1 and input 2 signals are too
close together.
Input contact de-
bounce filter Programmable contact debounce filter. Input signal frequency speed se-
lections of Hi (no filter), Med (250 Hz max input, 2 ms pulse width), and
Low (100 Hz max input, 5 ms minimum pulse width).
Time base Second, minute, hour, or day
Gate Low gate: 1-99 seconds; High gate: 2-9,999 seconds

Rate display units Gallons, liters, imperial gallons, cubic meters, barrels, bushels, cubic yards,
cubic feet, cubic inches, liquid barrels, beer barrels, hectoliters, or custom.
Rate display time
base Display rate may be calculated in terms of units per second, minute, hour,
or day.
Total and grand total
display units Gallons, liters, imperial gallons, cubic meters, barrels, bushels, cubic yards,
cubic feet, cubic inches, liquid barrels, beer barrels, hectoliters, or custom.
Setting is independent for each.
