NOTE: Battery shelf life is rated at 10 years by manufacturer Life expectancy based on rated battery capacity at 20°C 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%.

DISPLAY:

Rate Display: (selectable decimal)

5 Digits (99999), 0.35" High, Display updates once per second with battery power, 8X per second with DC or Loop power

Rate Descriptors: /SEC, /MIN, /HR

Min. Input Frequency: 0.01 Hz to 10 Hz (selectable delay of 0.1 to 99.9 seconds)*

Selectable Rate Display Damping Totalizer Display: (selectable decimal)

Totalizer Descriptors: GAL, LIT, FT3, M3, "blank"

Warning Displays: Low battery warning

PULSE OUTPUT:

The pulse output advances with the least signifi cant digit of the totalizer or decimal multiples there of (see Pulse scale divider). Type: Isolated photomos relay

Max. voltage (off state): 30 VDC

Current (on state): 100mA

Pulse Duration: Selectable 0.5, 0.25, 0.125, 0.0625 seconds

Pulse Scale divider (Pulscale): User selectable, ÷1, ÷10, ÷100 or OFF

INPUTS:

MAGNETIC PICKUP INPUT

Frequency Range: 0 to 3500 Hz

Trigger Sensitivity: 30 mV p-p (10 mV p-p on special order)

Over Voltage Protected: ± 30 VDC

OPTO-ISOLATED DC PULSE INPUT High (logic 1): 4-30 VDC

Low (logic 0): Less Than 1 VDC

Minimum Current: .5 mA

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 : Sustained contact closure will shorten battery life.

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.

* A large delay setting and internal math operations may delay the update rate.
