Logic High: 2-24 V, Logic Low: < 1 V
Maximum Frequency: 20 kHz
Minimum Pulse Width: 20 µs
Input Current: 1 mA @ 5 V,
2.5 mA @ 12 V, 5 mA @ 24 V
Low Voltage Mag Sensitivity: 20 mVp-p to 24 Vp-p
Pickup Input Maximum Frequency: 6 kHz
Minimum Input 0.0001 Hz. Minimum frequency is
Frequency dependent on high gate setting
(rate display).
Input Impedance
Pulse input: Greater than 75 kΩ @ 1 kHz.
Open collector/switch input:
100 kΩ pull-up to 3 V.
Accuracy ±0.03% of calibrated span ±1 count
Temperature Drift Rate display is not affected by changes
in temperature.
Low-Flow Cutoff 0.1 to 99,999 or disable. Point below at
which the display always shows zero.
Decimal Point Up to four decimal places or none:
4. 4 444, 33. 3 33, 222. 2 2, 1111. 1 , or 00000
Calibration May be calibrated using K-Factor, scale
without signal source, or by applying an
external calibration signal.
K-Factor Field programmable K-Factor converts
input pulses to rate in engineering 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 Programmable contact debounce filter.
Debounce Filter Input signal frequency speed selections
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

independently programmed, and are
independent of rate decimal point.
Totalizers Calculates total and grand total based
on rate and field programmable
multiplier to display total in engineering
units. Time base must be selected
according to the time units in which the
rate is displayed. The total and grand
total utilize the same time base, with
different conversion factors and resets.
Totalizer Reset Via SafeTouch RESET button,
mechanical button (cover off), external
contact closure (total only),
automatically via user selectable preset
value and time delay (1 – 99,999 sec).
Manual reset may be disabled or
protected by password for the total and
grand total. Total and grand total reset
independently.
