SETUP AND PROGRAMMING
There is no need to recalibrate the meter for freq uency in
Hz when first received from the factory.
The meter is factory calibrated for Hz prior to shipment.
The calibration equipment is certified to NIST standards.
Overview
Setup and programming is done through the infrared through-glass SafeTouch®
buttons, or using the mechanical buttons when uncovered. There are three slide
switches located on the display module. Two are used to configure the input and the
other is to lock or unlock the SafeTouch
®
Buttons.
Page 21
PD6830 Pulse Input Rate/Totalizer Instruction Manual

SafeTouch® Buttons
The PD6830 is equipped with four sensors that operate as through-glass buttons so
that it can be programmed and operated without removing the cover (and exposing
the electronics) in a hazardous area. These buttons can be disabled for security by
selecting the LOCK setting on the switch located on the connector board in the base
of the enclosure. To actuate a button, press and remove one finger to the glass
directly over the marked button area. When the cover is removed, the four
mechanical buttons located next to the sensors are used. The sensors are disabled
when a mechanical button is pressed and will automatically be re-enabled after
60 seconds of inactivity.
The SafeTouch
®
Buttons are designed to filter normal levels of ambient interference
and to protect against false triggering, however, it is recommended that the
SafeTouch
®
Buttons be disabled (slide switch to LOCK) if there is an infrared
interference source in line-of-sight to the display or if the buttons are not needed.
SafeTouch
®
Button Tips:
To remove cover with power applied (safe area only), or to clean the window,
select CLEAN from the SERVICE menu before opening the cover or cleaning the
glass. This will temporarily disable the SafeTouch
®
buttons for 60 seconds to
prevent inadvertent use. Use the mechanical buttons while the meter is open.
To the extent possible, install the display facing away from sunlight, windows,
reflective objects and any sources of infrared interference.
Keep the glass window clean.
Tighten the cover securely.
Use a password to prevent tampering.
After all connections have been completed and verified, connect the ribbon cable to
the display module, fasten the display module to the base, install enclosure cover,
and then apply power.

Programming the Meter (PRoG)
It is very important to read the following information, before proceeding to program
the meter:
There is no need to recalibrate the meter for frequency in Hz when first
received from the factory.
The meter is factory calibrated for Hz prior to shipment. The calibration
equipment is certified to NIST standards.
Use the Factor menu to enter a K-Factor - or
Use the Scale menu to enter the default 2-point scaling without a signal source - or
Use the Calibrate menu to apply a signal from a calibrator or a flowmeter for the
default 2-point scaling.
Note: The K-Factor, Scale, and Calibrate functions are exclusive of each other.
The meter uses the last function programmed. Only one of these methods can
be employed at a time. The Scale and Calibrate functions can use up to 32
points (default is 2). The number of points should be set in the Advanced menu
under the Multi-Point Linearization (LINEAR) menu selection prior to scaling and
calibration of the meter, see page 44 for details.
Additional parameters, not needed for most applications, are viewed and
programmed in the Advanced menu. See Advanced Features Menu page 40.
Page 30
PD6830 Pulse Input Rate/Totalizer Instruction Manual

K-Factor (Factr)
The meter may be scaled using the K-Factor function. Most flowmeter manufacturers
provide this information with the device. Enter the K-Factor (Factr) menu and select
the decimal point with highest resolution possible and program the K-Factor value
(i.e. pulses/gal). The meter will automatically calculate the flow rate using the
K-Factor and the time base selected and the following scaling selection will be
skipped.

Error Message (Error)
An error message indicates that the ca libration or scaling process was n ot successful.
After the error message is displayed, the meter reverts to input 2 during calibration or
scaling, allowing the appropriate input signal to be applied or programmed.
The error message might be caused by any of the following conditions:
1. Input signal is not connected to the proper terminals or it is connected backwards.
2. Minimum input span requirements not maintained.
3. Input 1 signal inadvertently applied to calibrate input 2.
Minimum Input Span
The minimum allowed input span is 1 Hz, w hich is the minimum d ifference b etween input
1 and input 2 signals required to complete t he calibration or scaling of the meter.

Gate Function (Gate)
The gate function is used for displaying slow pulse rates. Using the programmable
gate, the meter is able to display pulse rates as slow as 1 pulse every 999 seconds
(0.001 Hz). The gate function can also be used to obtain a steady display reading
with a fluctuating input signal.
There are two settings for the Gate, low gate (Lo Gate) and high gate (HI Gate).
Low Gate (Lo Gate)
For most applications, low gate setting should be left at 1 second. Increase low gate
setting to obtain a steadier rate display. The rate display will update in accordance
with the low gate setting, for example if low gate is set at 10, the display will update
every 10 seconds; changes in rate between updates will not be reflected until next
display update.
High Gate (HI Gate)
Set the high gate value to correspond to the highest expected pulse period (lowest
pulse rate). For instance if the meter must display a rate when there is 1 pulse
coming into the meter every 10 seconds, set the high gate to 11 seconds. When the
signal is removed from the meter, the display will show the last reading for 11
seconds; then it will read zero.
Page 44
PD6830 Pulse Input Rate/Totalizer Instruction Manual
44
Multi-Point Linearization (LINEAR)
Up to 32 linearization points can be selected under the Linear function. The multipoint linearization can be used to linearize the display for non-linear signals such as
those from level transmitters used to measure volume in odd-shaped tanks or to
convert level to flow using weirs and flumes that require a complex exponent. These
points are established via direct entry (SCALE) or with an external calibration signal
(CAL).
Number of Points (NO PTs)
Enter number of linearization points. The default value is 2 points. After entering the
number of points, the next selection is Scaling (page 31) or Live Input Calibration
(page 32).
Manual Entry (SCALE)
Manual entry of the linearization data is done once the number of points has been
selected (NO PTS). Input signal levels (InP 1-32) for up to 32 points, along with the
desired/corresponding meter reading (dSP 1-32) should be entered for each linearization point. See Figure 13 on page 45.
External Calibration (CAL)
Linearization data can be entered using a known accurate signal source (InP 1-32)
and then entering the desired/corresponding meter reading (disp 1-32) for that
input signal level See Figure 13 on page 45.
Important Navigation Note:
After entering the last display value, the linearization entries must be saved (SAUE?)
before they will be put into effect. However, you may move past this selection using
the Up arrow key if you need to go back and correct and earlier entry. Once confident
in the entries however, the user must navigate back to the Save menu screen
(SAUE?) and press the Enter/Ack key to save the changes.

Contact Debounce Filter (FiLter)
The filter function (FiLter) can be used for applications where the meter is set up to
count pulses generated by switch contacts. There are two settings, HI (high speed)
and LO (low speed). High speed disables the contact debounce filter and allows any
pulse of the minimum specified width for the input wired. Press ENTER when LO is
displayed to enable the filter function. Program the filter value for the maximum frequency of the true pulse signal in Hz that is expected plus a small margin. In most
applications, a setting of 40 will be sufficient to debounce a contact closure, yet allow
a pulse train up to 40 Hz.
Low-Flow Cutoff (CUTOFF)
The low-flow cutoff feature allows the meter to be programmed so that the oftenunsteady output from a transmitter at low flow rates, always displays zero on the
meter.
The cutoff value may be programmed from -99999 to 99999. Below the cutoff value,
the meter will display zero. Programming the cutoff value to zero disables the cutoff
feature.
Output Internal Calibration (OCAL)
This feature is only used at the factory and for diagnostic purposes. It is not
recommended to access this menu without instruction from technical support.
Backlight (BAKLITE)
The Backlight menu is used to enable or disable the backlight. This feature is
particularly important for the battery-powered models with momentary backlight.
Information (INFO)
The Information menu is part of the Advanced features menu. It shows software
identification number and version number. To determine the software version of a
meter:
Go to the Information menu (INFO) and press ENTER button.
Continue pressing ENTER to scroll through the software release number and
