The above table is shown with pulse output inactive. Use
of pulse output shortens battery life.
Example: A pulse output of 0.06 sec. duration, once per
second, would derate the battery life by 20%.

Hysteresis: 0.4 VDC
Frequency Range: 0 to 5 kHz
Min. Pulse Width: 0.1 msec
CONTACT CLOSURE INPUT (contact closure to common)
Internal Pullup Resistor: 100 KΩ to +3.6 VDC
High (logic 1): Open or 4-30 VDC
Low (logic 0): Less Than .5 VDC
Internal Switch Debounce Filter: 0 to 40 Hz
NOTE:
Sustained contact closure will shorten
battery life.
RESET INPUT (contact closure to common)
Internal Pullup Resistor: 100 KΩ to +3.6 VDC
High (logic 1): Open or 4-30 VDC
Low (logic 0): Less Than .5 VDC
Minimum On : 25 msec
NOTE:

K-FACTOR
Range: 0.001 to 99999999
Decimal Point Locations: XXXX.XXXX to XXXXXXXX
20 POINT LINEARIZATION -LIN OPTION
This feature allows the user to enter 20 different frequencies
with 20 different corresponding K-Factors to linearize non linear
signals.
ANALOG OUTPUT -MA OPTION:
Type: 4-20 mA follows rate display, Two wire hookup
Accuracy: 0.025% Full Scale at 20° C
Temperature Drift: 50 ppm/°C Typical
Reverse Polarity Protected
Update Rate: 8 times/second
NOTE: The DPF500 uses the 4-20 mA loop power as its primary
power source when this option is used. The battery is still
required for standby battery operation.
DATA STORAGE:
Setup Information: Stored in fl ash memory
Totalizer: Stored in battery backed RAM but can be saved to
fl ash memory by operator for recall after battery change out.
