3. PRODUCT INTRODUCTION
Our counters are a versatile, cost effective solution to a wide range of monitoring and control
applications including frequency, rate, total, period, time, phase, position, and flow. Setup can
be via front panel pushbuttons or a PC. Selective lockout of front panel keys protects against
accidental or unauthorized setup changes and simplifies meter use.
A dual-channel pulse or AC input signal conditioner board accommodates a wide range of
applications including rate/frequency, totalizing, timing, phase angle, power factor, and duty
cycle. Frequency and rate are determined by taking the inverse of period. Fast read rate is
ideal for peak or valley capture and allows quick response for control applications. Adaptive
digital filtering provides stable readings and control outputs while responding rapidly to actual
changes of the signal. A high stability quartz crystal and digital calibration assure accurate rate
and analog measurements.
A process receiver & totalizer signal conditioner board accepts 4-20 mA, 0-1 mA or 0-10V
analog signals for display of rate or position. Square root extraction is selectable for use with
differential pressure flow transducers.
A quadrature signal conditioner board provides accurate display of position, angle, or rate.
USB, RS232, or RS485 (2-wire half-duplex or 4-wire full-duplex) serial communi- cations
options are available with the Modbus protocol or a simpler custom ASCII protocol. Modbus
operation includes R U or ASCII modes, up to 247 digital addresses, and up to 32 devices per
RS485 line without a repeater. USB-to-RS485 converter boards allow a meter to be interfaced
to a PC and to multiple meters on an RS485 network
Meter programming can be via the meter’s front panel or a PC running Windows based
Instrument Setup Software. A serial interface option is required.
A standard switching power supply allows the meters to be powered worldwide from 85 to
264 Vac. An optional power supply operates from batteries or low voltage sources, such as 12-
32 Vac.
A built-in isolated excitation supply with jumper-selectable 5, 10 or 24 Vdc output levels is
standard and can eliminate the need for an external sensor power supply.
A dual or quad relay board is optional for alarm or control. he relays can be Form C 8A
mechanical relays or 2 or 4 Form A 130 mA solid state relays. he setpoints can be latching or
non-latching, be energized above or below the setpoint, or operate in a fail-safe mode.
A single or dual isolated analog output board is optional. With dual outputs, one of the
outputs can be assigned to the reading (such a rate), while other reading is assigned a non-
displayed item (such as total). he outputs can be 0-20 mA, 4-20 mA, 0-10V, or -10V to +10V.
Operation as a 6-digit serial input meter is achieved with a serial interface and no signal
conditioner board, allowing the unit to serve as the remote display of a computer, PLC or other
meter. With an optional dual or quad relay board, the unit can provide local alarm or On/Off
control. With an optional analog output board, it can also serve as a local isolated transmitter.
The meter case meets the 1/8 DIN size standard and is sealed to NEMA-4X (IP65) when
panel mounted. Mounting is from the front of the panel and requires less than 110 mm behind
the panel. All wiring is via removable plugs conforming to IEC950 safety standards. All output
options are isolated from meter and power grounds to 250 Vac.

8. RONT PANEL SETUP KEYS
Counter Front Panel
here are four front panel keys, which change function for the Run Mode and Menu Mode,
effectively becoming eight keys. he keys are labeled with alphanumeric captions (MENU,
PEAK, RESE , ALARMS) for the Run Mode and with symbols ( right arrow, right
triangle, up triangle, left arrow) for the Menu Mode.
RONT PANEL LOCKOUT
he Menu Mode will not work with most meters shipped from the factory, since all menu
items have been disabled in software and a lockout jumper is in place. his jumper needs to
be removed for the Menu Mode to work, and values under _Loc 1 through _Loc 4 need to
be set to "0" via the front panel for these menu items to be available. See Section 9. he
paragraphs below assume that all lockout features have been removed.
MENU MODE KEY ACTION
In the Menu Mode, pressing a key momentarily advances to the next item. Holding down
the key advances through multiple menu items for fast menu navigation.
KEYS IN RUN MODE
MENU Key. Pressing MENU from the Run Mode enters the Menu Mode. Pressing
MENU repeatedly will step the meter through the various menu items (if these have not
been locked out) and then back to the Run Mode.
PEAK Key. Pressing PEAK causes the peak value of the input signal to be displayed.
he peak display blinks to differentiate it from the normal present value display.
Pressing PEAK again will return the display to the present value.

11
RESET Key. Pressing RESET with PEAK resets peak and valley values. Pressing
RESET with ALARMS resets latched alarms. Pressing RESET with MENU performs a
meter reset (same as power on). Pressing and releasing RESET without pressing
another key changes the displayed item if the mode has multiple items. For Item 1, the
V LED is out. For Item 2, the V LED is on. For Item 3, the V LED is flashing.
ALARMS Key. Pressing ALARMS once displays the setpoint for Alarm 1. Pressing it
again displays the setpoint for Alarm 2. Pressing it again returns to the present value.
After 30 seconds, the meter automatically returns to the present value. iming is
automatically reset whenever the ALARMS key is pressed.
KEYS IN MENU MODE
Right Arrow Key (MENU). Pressing steps the meter through all menu items that
have been enabled and then back to the Run Mode. With the dual-channel pulse input
signal conditioner board and no option boards, available menu items will be _InPut,
SEtuP, Con iG, dSPYno, etc. Actual menu items will vary depending on the In ut
selection and boards detected in the meter. If a change has been made to a menu item,
that change is saved to non-volatile memory when the key is pressed next, and
_StoreE is displayed briefly.
Right Triangle Key (Digit Select).
• Pressing from the InPut menu brings up all meter functions available with the
meter's signal conditioner. For the dual-channel pulse input signal conditioner, these
are _rAtE_, PEriod, _totAL, ti_Int, Stop_t, _PHASE, duty_C.
• Pressing from most menus selections sequentially selects digit positions 1 - 6, as
indicated by a flashing digit: 000000, 000000, 000000, 000000, 000000, 000000.
• Pressing from dEC.Pt1 brings up a decimal point display of type 11.1111. Pressing
from dEC.Pt2 brings up a decimal point display of type 22.2222.
Up Triangle Key (Value Select).
• Pressing from a selected meter function, such as _rAtE_, will select the a specific
operating mode within that function, such as A_OnLy. Always press the MENU key
to save your selection. Do not press the key to the right, or your selection will be
lost.
• Pressing for a flashing digit position or decimal point position will increment that
item. Pressing the MENU key will save any changes.
Left Arrow Key (Reverse Menu). Pressing has the same effect as the MENU key,
except that menu items are brought up in reverse order.

9. ENABLING & LOCKING OUT MENU ITEMS
For security reasons and ease of operation, any and all menu items
may be disabled or "locked out" so that they are no longer directly
accessible from the front panel. Each function to be enabled is set
to "0" and each function to be disabled is set to "1" in menu items
Loc 1-4. hese menu items can in turn be locked out by installing an
internal hardware jumper. With the jumper installed, the operator
only has access to enabled menu items. With the jumper removed,
the operator also has access to the Loc 1-4 menu items.
SETTING HARDWARE LOCKOUT JUMPER
o access the lockout jumper, remove the rear panel per Section 9
and locate jumper “a” in the lower portion of the power supply board
next to the input connectors (see figure at right).
SETTING SO TWARE LOCKOUTS
When setting up the meter, it may be neces-
sary to enable specific menu items by setting
the corresponding lockout digit to 0. Be sure
to reset the lockout digit to "1" if you do not
want the menu item to be changed by an
operator.
_Loc 1 _Loc 2 _Loc 3 _Loc 4
Press the MENU key until Loc 1, Loc 2,
Loc 3 or Loc 4 is displayed, as desired. Note:
the lockout jumper must be removed (see
above).

10. DUAL CHANNEL PULSE OR AC INPUT SIGNAL CONDITIONER
he dual channel signal conditioner board is used for the frequency, rate, period, timing,
batch control, phase and duty cycle meter functions. he board needs to be configured via
jumpers for the input signal type and level. It is recognized by the meter software, which will
bring up the applicable menu items. he dual channel pulse input signal conditioner does
not require calibration, since the quartz crystal oscillator used for frequency and timing
applications is located on the counter main board.
Note: Letters indicate
jumper position. Jumpers are
installed on pins adjacent to
letters.
Jumper Settings for Expected Signal Levels
he jumper settings for Channel A (A2 & A3) and Channel B (B2 & B3) need to be set for
the expected signal voltage. his voltage must be outside of the high and low thresholds per
the following table, or the meter will not operate properly. he larger the difference between
the high and low thresholds, the more immune the meter is to input signal noise.

OVERVIEW O OPERATING MODES
RATE & REQUENCY MODES
requency in Hz is determined by timing an integral number of pulses over a user-specified
gate time from 0 to 199.99 sec and taking the inverse of average period. he typical display
update rate of the meter is gate time + 1 period + 30 ms Selecting a longer gate time
produces a more stable reading as more cycles are averaged, but slows down the update
rate. At very low frequencies, the update rate is controlled by the period. A time-out from 0
to 199.99 sec is also selectable. his is the time the meter waits for a signal to start or end a
conversion. If the signal is not received before the time-out ends, the meter reads zero. he
longer the time-out, the lower the minimum frequency the meter can display.
With a scale factor of 1 and multi lier of 1, frequency is displayed in Hz with no decimal
point. Appling a multiplier from 1 to 100000 (in decade steps) and setting the decimal point
increases resolution (0.1 to 0.00001 Hz). Decreasing the multiplier from 1 to 0.00001 (in
decade steps) and setting the decimal point allows display in kHz or MHz. Note that the
same 100 kHz frequency can be displayed as 100000 Hz or 100.000 kHz simply by moving
the decimal point.
DISPLAY REQUENCY IN Hz WITH 1 Hz RESOLUTION
Application:
Display frequency from 1 Hz
to 999999 Hz with no decimal, display up-
date rate of 4/sec, and adaptive moving
average filter for 6 readings.
Solution:
Set Input to “Rate A Only.” Set
Config to display to 999999 counts. Set
Gate ime to .22 sec so that the dis
play
update rate be
comes .22 sec +30 ms +1
period. Set ime-out to 1 sec, so that fre-
quencies under 1 Hz are displayed as 0.
Set filter for adaptive moving average with
a 1.6 sec time constant. Apply a scale
value of 1.00000 and multi
plier of 1 for
direct readout in Hz.

15
DISPLAY 0-50.00 RATE ROM 1-10 kHz INPUT, COORDINATES O 2 POINTS METHOD
Application: Display 0-
50.00 (with two
decimal places) for 1-
10 kHz input. Use
coordinates of 2 points scaling method.
Solution:
Set Input to “Rate A Only.”
Select “coordinates of 2 points” scaling
method under Setup. his is easier than
scale and offset. Set DecPt1 to two places.
hen enter the low input and desired low
reading, and high input and desired high
reading, as shown.
DISPLAY RATE IN GPM ROM 36.67 PULSE/GALLON TURBINE LOW METER
Application:
Display rate in GPM to two
decimal places from flow meter calibrated
to 36.67 pulses/gallon.
Solution: Set Input to “Rate A Only. Un-
der Setup, select “coordinates of 2 p
oints”
scaling method. Set DecPt1 to two places.
hen enter the low input and desired low
reading, and high input and desired high
reading, as shown. In this example, we
want to display 60.00 (GPM) from an input
of 36.67 Hz. Note that the meter’s native
r
ate measurements are in Hz. here will be
60 times more gallons per minute than per
second.
Rate in engineering units is displayed from measured frequency by applying an appro-
priate scale factor and setting the decimal point. he scale factor consists of a scale value
from 0.00000 to 9.99999 (fixed decimal point and settable digits) and a scale multi lier from
0.00001 to 100000 (in decade steps). When using the coordinates of 2 oints method to
scale the meter, the low input and high input frequencies are entered in Hz.
• RATE A ONLY (A_OnLy) displays rate or frequency for Channel A. he latter utilizes
SCALE1, OFFSt1 and dECPt1. Channel B is not used.
• RATE A B (A__b__) displays rate or frequency for Channel A as Item #1 or for Channel
B as Item #2. he latter utilizes SCALE2, OFFSt2 and dECPt2.
• RATE A, TOTAL A (A_Atot) (Extended counter) displays Rate for Channel A as Item #1
and otal for Channel A as Item #2 since last reset. otal may count down from an offset
by entering a negative scale factor. Only used for non-linear inputs.

16
• RATE A, TOTAL B (A_btot) (Extended counter) displays Rate for Channel A as Item #1
and otal for Channel B as Item #2.
• RATES A+B, A-B, AxB, A/B, A/B-1 (Extended counter) display arithmetic combinations
of Rates A and B as Item #1, Rate A as Item #2, and Rate B as Item #3. With rates A and
B scaled to produce a ratio close to 1 and an offset of -1, the special combination A/B-1,
called “Draw,” can display percentage changes, such as elongation of material as it
passes between rollers.
TOTAL MODES
DISPLAY TOTAL IN GALLONS ROM 36.67 PULSE/GALLON TURBINE LOW METER
Application:
Display total in gallons with
two decimal places for flow meter calibra-
ted to 36.67 pulses/gallon.
Solution: Set Input to “ otal A Only.” Un-
der Setup, select “Restore totals at power-
on” and coordinates of 2 points method.
his is the preferred scaling method. Set
gate time to its minimum of 0.01 sec for
smooth display updates. Set DecPt1 to two
places. hen enter low input and desired
low reading, an
d high input and desired
high reading for display of 1.00 for 36.67
pulses, as shown.
DISPLAY SIMULTANEOUS RATE & TOTAL ROM 36.67 PULSE/GALLON LOW METER
Application:
Display flow rate in GPM with
two decimal places and total gallons with
no decimal places from the same flow me-
ter signal calibrated to 36.36 pulses/gallon,
applied to Channel A
Solution: Use an Extended coun
ter, as
required for simultaneous rate and total.
Set Input to “Rate A A otal.” For flow rate
in GPM (Item #1), set DecPt1 to two deci-
mals, and scale the display by entering Lo
In1, Lo rd1, Hi In1, Hi rd1 as shown. For
total in Gallons (Item #2), set DecPt2 to no
deci
mals, and scale the display by entering
Lo In2, Lo rd2, Hi In2, Hi rd2 as shown.
Enter a Gate ime, such as 0.1 s
ec, which
is long enough to produce stable rate read-
ings, but is short enough to produce rapid
updates of total.

17
DISPLAY TOTAL VOLUME BY ADDING TWO TURBINE LOW METER CHANNELS
Application:
Display total liquid volume in
gallons to two decimal places
from 2 pipes
dispensing liquids into the same tank. Flow
meter A is calibrated to 36.67 pulses/gal-
lon, flow meter B to 58.12 pulses/gallon.
Solution: Arithmetic operations re
quire the
Extended counter. Apply flow meter output
A output to Channel A, flow
meter output B
to Channel B. Set Input to “ otal A+B.” Set
Gate ime to 0.01 sec for fast display up-
dates. Select a positive trigger slope for A
and B. Set DecPt2, which applies to Grand
otal, and DecPt1, which applies to otals
A and B, both to two dec
imal places. Under
Setup, select the coordinates of 2 points
scaling method for A and B. o scale A,
enter 36.67 (pulses) for Hi In1 and 1.00
(gallons) for Hi Rd1. o scale B, enter

for Hi Rd2. he normal displa
y will be Item
#1 (Grand otal). Press the key
to view
Item #2 ( otal A) and Item #3 ( otal B).
TOTAL A ONLY (A_OnLy) displays the number of pulses applied to Channel A as Item #1. If
scientific notation is not selected, overflows beyond 999,999 are recorded in units of 1,000,000
as Item #2. For example, a total of 17,345,676 would be displayed as 345,675 in Item #1 and
17 in Item #2. his capability gives the counter 12-digit capability. Items #1-2 can also be
retrieved via serial communications.
• TOTAL A B (A__b__) displays otal A as Item #1 or otal B as Item #2.
• TOTALS A+B, A-B, AxB, A-B, A/B (Extended counter) display arithmetic combinations
of otals A and B as Item #1, otal A as Item #2, and otal B as Item #3.
• TOTAL A-B UD (A-b_Ud) is the same as O AL A-B, except that counts are subtracted
on an ongoing basis, instead of subtracting totals. his avoids round-off errors with large
totals. Overflows are displayed as #2. (See otal A only)
• BURST (_burST) (Extended counter) displays the total number of signal bursts applied
to Channel A as Item #1 and signal frequency within a burst as Item #2. Gate time must
be greater than the period of the lowest signal frequency and less than the minimum time
between bursts. ime-out must be greater than the maximum time between bursts.
• TOTAL A B U/D (A_bU/d) (Extended counter) displays otal A as Item #1, where the up
or down count direction is determined by an input on Channel B. If the menu item SLOPE
is set to 0 for Channel B, (digit 6), an input level on B below the jumper set Low
hreshold B causes the count to go up, and an input level above the jumper set High
hreshold causes the count to go down. If SLOPE for Channel B is set to 1, the opposite
occurs. he maximum frequency on A that can be counted is 250 kHz, or a minimum of 4
µs between pulses.

18
• TOTAL A B INHIBIT (A_bInH) (Extended counter) displays otal A as Item #1, where
counting may be inhibited by a control input on Channel B. If the menu item SLOPE is set
to 0 for Channel B (digit 6), a low input level on B allows counting, and a high input level
inhibits counting. If the SLOPE for Channel B is set to 1, the opposite occurs. he
maximum frequency on A that can be counted is 1 MHz. Overflows are displayed as #2.

BATCH CONTROL MODE (_bAtCH)
BATCH CONTROL WITH A 36.67 PULSE/GALLON TURBINE LOW METER
Application: Fill 55 gallon tanks, measur-
ing flow with a 36.67 pulses/gallon
flow
meter. Slow down filling at 54 gallons.
Cycle batches automatically with 20 sec
between cyc
les. Display batch total & fill
rate to 2 places. rack number of batches.
Solution:
Use an Extended counter with a
dual relay output board. Apply the flow
meter signal to Chan
nels A & B. Set Input
to “Rate Batch.” Set Batch to count up to
Setpoint1. Use Gate ime as delay be-
tween batches. Make Item #2 the number
of batches. Set Gate ime to 20 sec. Set
an adaptive moving average filter, which
will apply to rate only, not totals. Set
DecPt1 and DecPt2 to two decimal places
for Items #1 and #3 (Batch ota
l and Rate).
Scale Item #1 (Batch otal) by entering a
Scale1 of 2.72702 (counts per pulse) and a
Setpoint1 of 55.00, which will serve as the
batch setpoint in gallons. Scale Item #3
(Rate) using the co
ordinates of 2 points
method so that 36.67 pulses/sec
will be
dis
played as 60.00 GPM. Set Setpoint2 to
54.00 to activate Relay 2 to slow the fill
rate at 54.00 gallons.
Batch control (Extended counter) uses the meter with a dual relay controller board to
control repetitive fill operations. Relay #1 is used as the batch relay. Relay #2 (or Setpoint
#2) can be assigned to another limit, such as pre-warn to slow filling near the setpoint, end-
of-process, or rate alarm. he same signal is applied to Channels A and B. When digit 6 of
bAtCH (Action after Meter Reset) is set to zero, the following applies:
• In batch control mode without external resets, the meter waits until the RESET key is
pushed. It then energizes Relay #1 and displays the changing Batch otal. When the
preset value is reached, Relay #1 de-energizes for the duration of the gate time setting.
Relay #1 then re-energizes, the Batch otal resets, and the fill cycle repeats.

19
• In batch control mode with external resets, pushing the RESET key initiates cycling.
Grounding an external Gate input for a minimum of 3.33 ms then starts each new fill
cycle by energizing Relay #1 and resetting the Batch otal. Gate time is not used.
hree values are tracked and can be separately displayed by pressing the RESET key: Item
#1, the Batch otal; Item #2, the Grand otal of all batches or Number of Batches (select-
able during setup); and Item #3, the Fill Rate.
• Item #1, Batch Total, is the total for that batch. It may be configured to count up from 0 to
a preset, or to count down from a preset to 0. he preset value is placed in SETPT1.
SCALE1 is positive whether counting up or down.
• Item #2, Grand Total, is the sum of previous Batch otals and the current Batch otal. It
can overflow to exponential format.
• Item #2 (alternate), Number of Batches, is the current count of batches. SCALE1 does
not apply. dECPt1 is set to 1.
• Item #3, ill Rate, is calculated with a fixed 20 ms (or 1 cycle min) gate time. It may be
displayed as Item #3.
PERIOD MODES
• PERIOD A ONLY (A_OnLy) displays period of Channel A as Item #1.
• PERIOD A B (A__b__) displays period of Ch A as Item #1 and of Ch B as Item #2.
• PERIODS A+B, A-B, AxB, A-B, A/B (Extended counter) display arithmetic combinations
of Periods A and B as Item #1, Period A as Item #2, and Period B as Item #3.
TIMING MODES
STOPWATCH TIMING, “ON” TIME O A MACHINE WITH 0.00 HOUR RESOLUTION
Application:
Display daily “on” time of
a machine in hours with 2 decimals. For
machine maintenance, also track accu-
mulated hours since last reset.
Solution:
ie a relay across the AC input
to the machine so that the relay closes to
ground when power is applied. Apply the
relay output across both the A & B inputs
so that the voltage is 5V when the contacts
are open and 0V when they are closed. Set
Input to “Stopwatch A to B.” Select nega-
tive trigger slope for A and positive for B.
Under Config, set Display Mode to sec. Set
Gate ime to 0.01 sec. Select the coordi-
na
tes of 2 points scaling method for Item
#1 (daily time) and Item #1 (accumul
ated
time). For It
em #1, set DecPt1 to 2 places,
set Hi In1 to 3600 (sec) and Hi Rd1 to 1.00
(hrs). For Item #2, set DecPt2 to 0 places,
set Hi In2 to 3600 and Hi Rd2 to 1 (hr).

20
STOPWATCH TIMING, CLOSING TIME O A RELAY TO 0.001 MSEC RESOLUTION
Application: Measure the
closing time of a
relay in msec to 0.001 msec resolution.
Solution:
o close the relay, apply the
same posi
tive voltage to the relay coil and
to meter Channel A. Wire the relay so that
0V is applied across Channel B when the
contacts are closed. Set Input to “Stop-
watch A to B.” Select a positive trigger
slope for A and a negative trigger slope for
B. Under Config, set Dis
play Mode to sec.
Set Gate ime to 0.01 sec. Select the
coordina
tes of 2 points scaling method for
Item #1. Set DecPt1 to 3 places.
Set Hi In1
to 1.00000 (sec) and Hi Rd1 to 999.999
(msec). Ignore Item #2, which is not used.
• TIME INTERVAL A TO B (A_to_b) measures time between periodic inputs on Channels
A and B. iming starts when a pulse is applied to Channel A (positive edge if slope A is 0,
negative edge if slope A is 1), and ends when a pulse is applied to Channel B (positive
edge if slope B is 0, negative edge if slope B is 1). Pulse width may be measured by tying
inputs A and B together and selecting a positive or negative edge to start (Slope A) and
the opposite polarity edge to stop (Slope B). If multiple start and stop pulses occur during
the gate time, the displayed value is the average of pulse widths. he value is updated at
the end of each gate time. With a scale factor of 1, one count is one microsecond.
• INVERSE TIME INTERVAL (__1/Ab) (Extended counter)
akes the inverse of time interval for a reading in /second. For example, if the average
time interval for object to travel from point A to point B is 5 seconds, the inverse time
interval would be 0.2/sec. For the average speed of the objects, simply apply a scale
factor equal to the distance separating the two points, such as 7 (inches). Speed would
then be displayed as 7 x 0.2 = 1.4 (inches/sec). For a 6-digit reading, apply a scale
multiplier of 10,000 and move the decimal point.
• STOPWATCH A TO A (A_to_A) measures time between the same positive (or negative)
edge of start and stop pulses applied to Channel A. Single event times may be displayed
as Item #1 in decimal seconds, minutes or hours, or in HH:MM:SS clock format. ime is
reset to 0 when a new start pulse occurs. Accumulated total time may be displayed as
Item #2. With a scale factor of 1, one count is one microsecond.
• STOPWATCH A TO B (A_to_B) measures time between a start pulse on Channel A and
a stop pulse on Channel B. iming is the same as for A to A, except that positive or
negative edges may be selected separately for Channels A and B. his allows the pulse
width measurement of single pulses by tying Channels A and B together. One slope is
selected to start timing, and the opposite slope to stop timing.
