Introduction
The Loop Leader+ PD4-6600 Series of loop-powered
large display meters can be installed virtually
anywhere to provide convenient and informative
display of any 4-20 mA signal. One of the most
convenient features of these instruments is their
large, dual line display which is typically used to
display the process variable on the 2.8" 5-character
alphanumeric top display and the units of measure or
a tag on the 1.5" 8-character alphanumeric bottom
display. Another common setup is to display the input
in one scale on the top display (such as feet) and in
another scale on the bottom display (such as gallons).
Both display lines use 14-segment, alphanumeric
characters that provide much clearer indication of
tags, units, or alarm messages than 7-segment
characters do.
Further enhancing the display on these instruments is
a 20-segment bargraph that also includes a numeric
value of the percentage the bargraph represents.
These loop-powered meters can be installed virtually
anywhere because they get their power from the
4-20 mA loop and therefore require no separate power
source and they only have a voltage drop of 1.5 V, so
they add very little burden to the loop. Additional features
that allow these instruments to be installed virtually
anywhere include a NEMA 4X, IP65 rated enclosure, an
operating temperature range of -40 to 167°F (-40 to
75°C) (for safe area products), conformally coated
PCBs, and a backlit LCD that can be read in bright
sunlight or dimly lit areas. The PD4-6608 model is an
intrinsically safe and nonincendive version of the Loop
Leader+ that is agency approved for installation in
hazardous areas. It also carries electrical safety
approvals.
Free, PC-based, MeterView XL software that
connects to the meter via a USB cable is available for
programming and setup of the meters.
To download the latest MeterView XL programming
software and manual, visit predig.com/meterviewxl.
All models come equipped with two open collector
outputs and remote contacts. There are also models
available with two solid-state relays and isolated
4-20 mA analog output options. The open collector
outputs are useful for alarm indication. The remote
contacts can be used to remotely operate the four
programming buttons, to acknowledge the relays, to
start/stop a timer/stopwatch, and more. The relays
can be programmed for alarm indication, on/off
control, or pump alternation.

Key Features
1. Available on PD4-6604 only. Requires external 24 VDC power.
Large Informative Display
One of the most convenient features of the PD4
Loop Leader+ Series is its large, dual line display.
The PD4’s whopping 2.8" 5-character alphanumeric
top display and 1.5" 8-character alphanumeric bottom
display, plus a 20-segment bargraph with percentage
indication on top, makes reading and understanding
process values easier than ever.
Predefined display units give users even more display
flexibility. Plus, the high contrast backlit LCD display
is readable from far away and under various lighting
conditions.
Backlight Turns Red on Alarm
When an alarm occurs, the display can be
programmed to turn red and flash. In addition, a
unique custom alarm message for each of the two
relays and two open collectors can be displayed on
the bottom display. These features can be activated
even if no relay or open collector is connected.
Dual-Scale Feature
Users can use the dual-scale feature to display the
input in two different scales. For instance, the
example above shows an application where the
display shows the input in feet and gallons while the
display toggles between process values and units.
14-Segment Characters
Notice how much better letters like “T”, “N” and “K”
appear as 14-segment characters on the Loop Leader+
vs 7-segment characters found on many other meters.
Predefined and Custom Units
The meter has six available preprogrammed unit
classes: volume, height, temperature, pressure,
weight, and rate. When the desired unit class or unit
of measure within a class is not available, a custom
unit may be programmed.

Password Protection
A password can be set up for programming security to
prevent unauthorized changes to the programmed
parameter settings.
Remote Contacts
Remote Contacts are standard on the PD4 and the
meter can be operated via a remote control station
(PDA2364-MRUE). The PDA2364-MRUE mimics the
PD4 meter’s four programming buttons: Menu, Right
Arrow, Up Arrow, and Enter.
Multiple Outputs
• Two open collector outputs (standard)
• Two solid-state relays (optional)
• One 4-20 mA output (optional)
The open collector outputs and relays generally
operate in the same manner, with the major exception
being the open collectors are not available for pump
alternation and the relays are not available with pulse
features. The open collectors and relays can be
controlled either automatically or manually.
The isolated analog output signal can be configured
to represent the process variable (PV1, PV2, or
retransmit). It can also be reverse scaled such that
the meter’s high calibration value outputs 4 mA and
the meter’s low calibration outputs 20 mA.
Pump Alternation (ALTERN)
The PD4-6604 and PD4-6608 can be used as a pump
controller to alternate two pumps and indicate high and
low alarm conditions. The pumps can be programmed
to alternate on level and runtime and the display can be
programmed to turn red and flash a message on alarm
conditions. The meter can display the pump runtimes
and the number of times they have cycled.
See the Pump Control with Alternation & Alarm
Example on page 50 for full details.
Relay #2 turns the main pump on at 6000 gallons and
turns it off at 1000 gallons.
With the Pump Alternation feature activated, the next
time the level reaches 6000 gallons, relay #1 transfers
and starts the backup pump.

Input Signal Conditioning
Functions (FUNCTION)
The Function menu is used to select the input signal
conditioner applied to the input: linear, square root,
programmable exponent, or round horizontal tank
volume calculation. Multi-point linearization is part of
the linear function selection.
Meters are set up at the factory for linear function with
2-point linearization. The linear function provides a
display that is linear with respect to the input signal.
Square Root Linearization (SQROOT)
The square root function can be used to linearize the
signal from a differential pressure transmitter and
display flow rate in engineering units.
PD4-6604 Displaying Flow Rate by Applying the Square
Root Function to the Output of a DP Transmitter.
Programmable Exponent
Linearization (EXPONENT)
The programmable exponent can be used to linearize
the signal from level transmitters in open-channel flow
applications using weirs and flumes.
The PD4-6604, in combination with an ultrasonic level
transmitter, makes for an economical way to measure
and display open channel flow rate in most weirs and
flumes. A guide such as the ISCO Open Channel
Flow Measurement Handbook can provide the user
with all the information needed: the exponent used in
the flow equation for the desired flow units and the
flow rate for any given head height. For example, to
display the open channel flow rate from a 3" Parshall
flume, the ISCO handbook advises the exponent is
1.547 and at the maximum head height of 3.0 feet,
the flow rate is 3.508 MGD.
Round Horizontal Tank Linearization
(RH TANK)
This function automatically calculates the volume in a
round horizontal tank with flat ends and allows that
reading to be displayed on the bottom display. This
results in a meter that displays the height of the tank
on the top display and volume on the lower display.
The user only needs to enter the diameter and length
of the tank and meter takes care of the rest.
Set the display for the desired decimal point and
engineering units before entering the round horizontal
tank function. Select units (inches or cm) for the tank
dimensions. Enter the diameter and the length in
inches or cm and the results will be calculated
automatically in US gallons or liters. The unit of
measure for the volume can be changed using the
display menu.

Setup and Programming
Overview
There are no jumpers to set; setup and programming
is done by using the buttons (MENU, NEXT, UP,
ENTER) located behind the lower panel door of the
meter or PC-based software.
The meter may be powered via the USB connection
located behind the lower panel door of the meter for
the purposes of programming only. The backlight
requires an external power source. If the meter is
powered from the USB, the backlight will only work if
it is powered separately from a DC supply.
MeterView XL Programming Software
The fastest and easiest way to program the meter is
using the free Meterview XL programming software.
This software greatly simplifies the programming
process and allows the user to save configuration files
for later use.
The meter connects to the PC via a provided USB
cable and is powered by the USB connection, so no
additional power is needed during programming.
To download the latest MeterView XL programming
software and manual, visit predig.com/meterviewxl.
• The meter should only be connected to a
computer while it is located in a safe area.
• The image in the software shows the panel meter
version. The same software is used for the PD4.
• Care should be exercised to avoid ground loops
when connecting the USB to an active loop (e.g.
power supply, transmitter, loop-powered meter,
etc.). It is recommended to connect the (mA+)
terminal of the meter to the (-) terminal of a twowire transmitter and the (mA-) to the (+) of the
next device in the loop or to the (-) terminal of the
power supply.
The meter is factory calibrated prior to shipment
to display 0.00 to 100.00, which corresponds to
the 4-20 mA input. The calibration equipment is
traceable to NIST standards.

Scaling the 4-20 mA Input (INPUT)
It is very important to read the following information before proceeding to program the meter:
• The meter is factory calibrated prior to shipment to display 0.00 to 100.00 gal, which corresponds to the 4-20 mA
input. The calibration equipment is traceable to NIST standards.
• A calibrated signal source is not needed to scale the meter.
Enter the Input menu to scale the meter to display the 4-20 mA input. The input can accept any signal from 4 to 20 mA.
• Reverse Scaling
The meter can be scaled so that 4 mA represents the high end of the process value range being measured by the
transmitter and 20 mA represents the low end of the process value range.

Setting Custom Units (CUSTOM)
When the desired unit class or unit of measure within a class is not available, a custom unit may be programmed.
Select the CUSTOM menu (or CUSTOM unit within a unit class) to enter a custom unit name.
Text values are set using the Right and Up arrow buttons. Press Right arrow to select next character and Up arrow to
increment character value. The selected character will flash. Press and hold the Up or Right arrow buttons to autoincrement or decrement the character. Press Enter to accept the character.
Notes:
• Press and hold the Right-Arrow while no character is being edited to erase all characters to the right of the flashing character
• Press and hold Up or Right-Arrow to auto-increment or decrement a selected character.
• All text values, including tags and alarm messages, are set in a similar fashion.
Setting the Display Features (DISPLAY)
The meter’s display functions may be programmed using the Display menu. This menu consists of the following
submenus: Units, Decimal Point, Comma, Bargraph, Top, and Bottom.
Changing the Engineering Units (UNITS)
It is possible to change the engineering units within the selected unit class without the need to re-scale the meter.
When selecting a new unit from within the DISPLAY menu (e.g. changing from gallons (GAL) to liters (L)), the meter
will automatically convert the display values to display the new unit. Enter the UNITS menu, select a new unit of
measure from the list of predefined units, and press the Enter button. If entering a custom unit (CUSTOM), a custom
conversion factor will need to be entered.
Changing the Decimal Point (DEC.PT)
The decimal point may be set with up to seven decimal places or with no decimal point at all.
Pressing the Right-Arrow moves the decimal point one place to the right until no decimal point is displayed, and then
it moves to the left most position. Pressing the Up-Arrow moves the decimal point one place to the left.
If the dual-scale level feature is selected, the decimal point selections for PV1 & PV2 are enabled.

Programming the Bargraph (BARGRAPH)
The bargraph is a standard feature on all PD4 models and is useful in applications where a visual representation
of the process variable’s percentage of full scale is desirable. This feature can be enabled or disabled using the
Bargraph menu (BARGRAPH). The value displayed on the bargraph can be the percentage of full scale (PV PCT)
or the percentage of a user-programmable range (PV). If the meter is in dual-scale mode, the bargraph can be
assigned to display either PV1 or PV2 using this menu.
Programming the Outputs (OUTPUT)
All models come with two open collectors. Depending on the model purchased, the meter may include two solid-state
relays, and one 4-20 mA output. The Output menu will only show options for the available outputs. See Ordering
Information on page 10 for details.

Open Collector Outputs
(
OPEN COLLECTR
)
The meter is equipped with two NPN open collector outputs as a standard feature that may be set up for pulse
outputs, alarms, timed pulses, or disabled.
Pulse outputs can be set to transmit the PV value (PV1 or PV2 if meter is in dual-scale mode). Output 2 may be used
to generate a quadrature output based on the other open collector output. An output test mode is also selectable to
generate pulses at a constant programmable frequency.
Alarms are available based on the PV value or the digital input. The alarm status will show on the display even if the
output is not wired.
A timer output (TIMER) turns the open collector on and off at the specified time intervals. The timer can be set as
single-shot or continuous timer.
The stopwatch output (STPWATCH) allows the open collector to be manually activated by starting the stopwatch. The
stopwatch count can be displayed on the top or bottom display.
The output may be disabled by selecting DISABLE.
The Open Collector Outputs are programmed in the following manner:

Pulse Output (PULSE)
The pulse outputs may be programmed to generate a scaled frequency based on the PV and a programmable factor.
The factor determines the number of pulses per second generated per unit of measure. For example, if the meter
display shows 100 gallons and the factor is set to 2, the number of pulses generated per second would be 200. The
maximum frequency is 1,000 Hz.
Setting output 2 to quadrature will duplicate the other open collector output, but lag by 90 degrees out of phase. The
other output should be programmed as desired for the quadrature output function and must be a pulse (PULSE)
output selection. The quadrature maximum frequency for both outputs is 500 Hz.
The TEST option will output a fixed number of pulses per second based on the FREQ value entered.

Alarm (ALARM)
Alarm outputs may be assigned to the PV or the digital input. When assigned to the PV, the alarm may be set as
either a high alarm or a low alarm. Alarm actions (AUTO, AUTO.MAN, LATCH, L-CLEAR) determine how and when the
alarm should be reset. They operate as follows:
• Automatic (AUTO): Alarm will reset automatically once the alarm condition has cleared.
• Automatic/Manual (AUTO.MAN): Alarm will reset automatically once the alarm condition has cleared but can
also be reset using the Enter (ACK) button (or whichever function key is set to acknowledge) at any time.
• Latching (LATCH): Alarm must be reset manually and can be done so at any time. Press the Enter (ACK)
button at any time to clear the alarm.
• Latching with Reset after Clear (L-CLEAR): Alarm must be reset manually and can only be done so after
the alarm condition has cleared. Press the Enter (ACK) button after the alarm condition has cleared to reset
the alarm.
If the alarm is set to PV, a set and reset point must be programmed. The set point is the display value at which the
alarm will turn on and the reset point is the display value at which the alarm will turn off. If the set point is lower than
the reset point, the alarm will be a low alarm; if the set point is higher than the reset point, the alarm will be a high
alarm. The digital input alarm will trigger whenever the digital input is triggered.
For both the PV and digital input alarms, a delay before the alarm is turned on or off may be set, as well as a fail-safe
feature which reverses the on/off operation of the open collectors.
Alarm states will be displayed on the meter even if no open collector output is physically connected. These may include
a red LED backlight, flashing PV value (PV alarm only), and a programmable alarm message.

Flashing Red Alarm (RED)
The last two lines in the preceding menu flow chart show how to program the display to turn red, flash, and display a
message when an alarm occurs.
Alarm 1 is High Alarm:
Alarm 2 is Low Alarm:
Timer (TIMER)
The timer output may be set to generate the timed pulse only once (ONESHOT) or continuously (CONT).
The timer output produces a constant width pulse at a constant frequency, if set as continuous timer. Program the
Off Delay (OFF.DLAY) from 1 second to 99 hours 59 minutes and 59 seconds. This is the time it takes from selecting
START to turning on the output and for how long the output is off in continuous mode.
Program the On Time (ON TIME) for the active low pulse from 1 second to 99 hours 59 minutes and 59 seconds
(pulse width). This is the period of time for which the output will remain on.
Select Start (START) to begin outputting the constant timed pulse.
Select Stop (STOP) to end outputting the constant timed pulse.
Function keys or the digital input may be assigned to start and stop timer functions (see the USER menu in the
Advanced Menu).

Stopwatch (STPWATCH)
The stopwatch function may be used to manually run and control a process for a specific time interval up to 99 hrs.,
59 min, and 59 seconds. The stopwatch function may be assigned to any open collector. There are three settings
needed to use the function effectively.
1. Assign stopwatch to either top or bottom display line
2. Assign the open collector to control the
process (on/off)
3. Assign a function key or digital input to start/stop the stopwatch
Application Example
To maintain consistency of a product, it is necessary to take and test samples at different times throughout the day.
The stopwatch function is used to open and close a solenoid valve to know the exact amount of time needed to
complete the desired sample. Once this is determined, the timer function can be used to automatically take a sample
(batch) based on the time determined using the stopwatch function.
Setup: Assign the following to Stopwatch Function
• Bottom display line
(see pages 37 & 39 for details how to change the display)
• Relay 1
(see pages 41 & 46 how to change Open Collector and or Solid-State Relay functionality)
• F3: Start/Stop
(see pages 62 & 63 for details on how to change the function keys)
Procedure
• Press F3 to start the stopwatch; relay 1 turns on and the process starts running.
• Press F3 to stop the stopwatch; relay 1 turns off and the process stops.
• The bottom display indicates the time it took to complete the sample.

Solid-State Relay Outputs (RELAY)
The meter can be optionally equipped with two solid-state relays that may be set up for alarms, timer, stopwatch, or
pump control. Alternatively, they may be disabled.
Alarms are available based on the PV value or the digital input. The alarm status will show on the display even if the
output is not wired.
Pump control allows the relay to turn on and off a pump at specified on and off points. This can be done using only
one of the relays to control one pump (ON-OFF) or using both relays in tandem to alternate between two pumps
(ALTERN).
A timer output (TIMER) turns the relay on and off at the specified time intervals. The timer can be set as single-shot
or continuous timer.
The stopwatch output (STPWATCH) allows the relay to be manually activated by starting the stopwatch. The
stopwatch count can be displayed on the top or bottom display.
The output may be disabled by selecting DISABLE.
• During setup, the relays do not follow the input and they will remain in the state found prior to entering the Relay menu.

Pump Control (PUMPCTRL)
The pump control output is used in situations where the relays are used to control pumps. There are two options
available for controlling pumps: on-off (ON-OFF) and pump alternation (ALTERN).
ON-OFF will turn the relay on at a programmed on point and off at a programmed off point. Setting the on point higher
than the off point will make the output activate on a high PV value; setting the on point lower than the off point will
make the output activate on a low PV value. The relay will reset automatically.
For pump control applications where two similar pumps are used to control the level of a tank or a well, it may be
desirable to have the pumps operate alternately. This prevents excessive wear and overheating of one pump over the
lack of use of the other pump. Pump alternation uses both relays in tandem to alternate between two similar pumps.
The ALTERN menu is only available under Output 1 and will automatically set Output 2 to pump alternation as well.
Use the pump Alternation Time setting (ALT.TIME) to control the alternation based on runtime in addition to level
cycles.
On/Off Pump Control (ON-OFF)
When programming a single pump to turn on and off, the on and off points must be programmed. The relay will
activate at the on point and deactivate at the off point. On and off delays may be programmed to delay the activation
or deactivation of the relay by a certain number of seconds after reaching either the on point or off point.

Pump Alternation (ALTERN)
Pump alternation sets the two relays to alternate every time the first on point (ON 1) is reached. The active relay will
turn off once the first off point (OFF 1) is reached. If the PV reaches the second on point (ON 2), the other relay will
also turn on. The second relay will turn off once the second off point (OFF 2) is reached and the first relay will remain
active until the first off point (OFF 1) is reached.
On and off delays may optionally be programmed for each on and off point to delay the activation or deactivation of
the relays by a certain number of seconds after reaching either the on point or off point.
For pumps that typically remain on extensively, the alternation time (ALT.TIME) parameter sets a period of relay ontime after which the relays should alternate. For example, if the alternation time is set to one hour, pump 1 will turn off
after one hour of runtime regardless of the level reading, at which point pump 2 becomes the active pump. Pump 2
will run until one hour has passed, or the tank has reached a desirable level; whichever happens first. By using the
proper on/off points, the alternation can be set up so that the first pump on is the first pump off. This is desirable when
the two pumps are of similar rating.

The following graphics provide a visual representation of a typical pump alternation application:
Relay #2 turns the main pump on at 6000 gallons and
turns it off at 1000 gallons.
With the Pump Alternation feature activated, the next time
the level reaches 6000 gallons, relay #1 transfers and
starts the backup pump.
If the backup pump is not able to keep up, and the level
reaches 7000 gallons, relay #2 transfers and starts the
main pump as well. Open collector #1 trips the High
Level Alarm, the display turns red and flashes “Hi Level”
message indicating an alarm condition. The High Level
Alarm resets at 6500 gallons.
Once the level has dropped below the reset points, both
relays will turn off. If the Main Pump fails to turn off, open
collector #2 trips the Low Level Alarm at 1000 gallons to
warn against the pump running dry. The Low Level Alarm
resets at 1500 gallons.

Runtime & Cycle Count (INFO)
The relay information menu shows runtime and cycle count for each relay. These values may be cleared at any time
by selecting the Clear option (CLEAR?).
Isolated 4-20 mA Output (4-20 mA)
The 4-20 mA menu is used to scale the isolated 4-20 mA output based on display values. This menu is not present on
models without a 4-20 mA output option.
The 4-20 mA analog output can be scaled to provide a 4-20 mA signal for any PV display range or to simply
retransmit the 4-20 mA input. The output may be disabled (DISABLE), and will only output the minimum signal.
Overrange and underrange values determine what mA signal the meter will output if the mA input is underrange
(<3.5 mA) or overrange (>20.5 mA). This value may be set to 1 mA, 3.5 mA, 3.8 mA, 20.5 mA, 20.8 mA, 23 mA, or
disabled.
No equipment is needed to scale the analog output; simply program two display values and corresponding mA output
signals.
Process Variable (PV)
To scale the analog output, enter display value 1 and a corresponding analog output value for this display, and enter
display value 2 and a corresponding analog output value for this display value. This will provide a scaled linear
analog output.
Retransmit (RETRANS)
This option will retransmit the 4-20 mA analog input without the need to scale the output.
Output Manual Control (CONTROL)
The Control menu is used to control the open collector outputs, 4-20 mA analog output, and the relays manually,
ignoring the input. Each open collector, relay, and analog output can be programmed independently for manual
control. Selecting automatic control sets all relays and analog output for automatic operation.
After selecting manual control for a specific output, you can set the output value. To change the output value, return
to the Control menu, select the output to control, select manual control, and enter a new value.

Programmable Exponent Linearization (EXPONENT)
The programmable exponent can be used to linearize the signal from level transmitters in open-channel flow
applications using weirs and flumes.
The PD4-6604, in combination with an ultrasonic level transmitter, makes for an economical way to measure and
display open channel flow rate in most weirs and flumes. A guide such as the ISCO Open Channel Flow
Measurement Handbook can provide the user with all the information needed: the exponent used in the flow equation
for the desired flow units and the flow rate for any given head height. For example, to display the open channel flow
rate from a 3" Parshall flume, the ISCO handbook advises the exponent is 1.547 and at the maximum head height of
3.0 feet, the flow rate is 3.508 MGD.

Multi-Point Linearization (LINEAR)
Up to 32 linearization points can be selected for PV1 and
PV2 under the LINEAR function. Multi-point linearization
can be used to linearize the input so the meter can display
volume from non-linear tanks or to convert level to flow
using weirs and flumes with complex exponent. These
points are established via direct entry (SCALE) or with a
live calibration signal source (CAL).
If the dual-scale level feature has been selected, the
menus for PV1 & PV2 are enabled.

Advanced Scaling and Calibration (SCALE.CAL)
This menu offers options to scale or calibrate the meter.
Scaling the Input (SCALE)
The scale menu in the Advanced menu is the same as the scale menu in the Input menu. See Scaling the 4-20 mA
Input (INPUT) on page 35 for details about scaling the meter.
Calibrating the Input (CAL)
To scale the meter without a signal source, refer to
Scaling the 4-20 mA Input (INPUT), page 35.
The meter can be calibrated to display the process in engineering units by applying the appropriate input signal and
following the calibration procedure. The CAL menu can be used either with a calibrated current source or with a live
signal coming from a 4-20 mA transmitter connected to the process being measured.
During calibration, the mA input value will be displayed as INP 1 and INP 2. Adjust the input source until the
desired mA value is shown.
The use of a calibrated signal source is required.
Follow these steps to calibrate the input:
1. After accessing the SCALE.CAL menu, press the Right-Arrow button to scroll to the Calibration menu (CAL
PV) and press Enter.
2. Select the appropriate units for the desired process variable, then press Enter. For information on units,
see Available Unit Classes and Units on page 36.
3. The meter displays INP 1. Apply a known signal and press Enter. The display will flash while accepting the
signal.
4. After the signal is accepted, the meter displays DSP 1. Enter a corresponding display value for the input
signal, and press Enter to accept.
5. The meter displays INP 2. Apply a known signal and press Enter. The display will flash while accepting the
signal.
6. After the signal is accepted, the meter displays DSP 2. Enter a corresponding display value for the input signal
and press Enter to accept.
7. After completing calibration, the SAVE? display will need to be acknowledged using the Enter key before
calibration will take effect.

Low-Flow Cutoff (CUTOFF)
The low-flow cutoff feature allows the meter to be programmed so that the often-unsteady output from a differential
pressure transmitter at low flow rates always displays zero on the meter. The cutoff value may be programmed from 0.1
to 99999. The meter will display zero below the cutoff value. The cutoff can be disabled to display negative values.
Noise Filter (FILTER)
The noise filter is available for unusually noisy signals that cause an unstable process variable display. The noise
filter averages the input signal over a certain period of time. The filter level determines the length of time over which
the signal is averaged. The filter level can be set between 1 and 16 seconds or turned off. The higher the filter level,
the longer the averaging time and so the longer it takes the display to settle to its final value. Setting the filter level to
off disables the filter function.
Noise Filter Bypass (BYPAS)
The noise filter bypass changes the behavior of the meter so that small variations in the signal are filtered out but
large abrupt changes in the input signal are displayed immediately. The bypass value determines the minimum
amount of signal change to be displayed immediately. All signal changes smaller than the bypass value are filtered or
averaged by the meter. The noise filter bypass may be set between 0.1 and 99.9% of full scale.
Enabling Password Protection (PASSWRD)
The Password menu is used for programming security to prevent unauthorized changes to the programmed
parameter settings.
To set a password, enter the Password menu and program a five-digit password. For instructions on how to program
numeric values see Setting Numeric Values on page 34.
Making Changes to a Password Protected Meter
If the meter is password protected, the meter will display the message LOCKED when the Menu button is pressed.
Press the Enter button while the message is being displayed and enter the correct password to gain access to the
menu. After exiting Programming Mode, the meter returns to its password protected condition.
Disabling Password Protection
To disable password protection, access the Password menu and clear the entered password either by pressing and
holding the Right Arrow button until all digits reset to zero or manually changing all the digits to zero. When the Enter
button is pressed, the meter will display UNLOCKED and will no longer require a password to access Programming
Mode.
Note: If the meter is password protected and the password has been forgotten, the password may be overridden using the master
password: 50865

Programmable Function Keys User Menu (USER)
The User menu allows the user to assign the front panel function keys F1, F2, and F3, and the digital input (located
on the input signal connector) to access some of the menus or to activate certain functions immediately (e.g. reset
max & min, hold relay states, etc.). This allows the meter to be greatly customized for use in specialized applications.
Tare (TARE)
The tare function zero’s out the display. In the case of scale weight, tare is used to eliminate container weight and
provide net weight readings. There are two tare functions; Tare and Reset Tare. When the tare function is used, the
display reading is offset by the displayed amount to make the displayed value zero. Reset tare removes the display
offset of the net value, and the gross and net values become the same until a new capture tare is entered.
Program a function key or the digital input for the tare and reset tare.

Changing System Settings (SYSTEM)
The System menu contains the following menus:
Analog Output Calibration, Restore Factory Defaults,
Dual-Scale (PV2), Backlight, Information, and Internal
Calibration.
Analog Output Calibration (AOUTCAL)
To perform the analog output calibration, it is
recommended to use a milliamp meter with a
resolution of at least 0.1 µA to measure the output
current. The values saved internally during this
procedure are used for scaling the 4-20 mA output in
the Setup menu.
4-20 mA Output Calibration Procedure
1. Go to the Advanced Features menu and
navigate to the SYSTEM menu and press
Enter. Navigate to AOUTCAL and press Enter.
2. The display will show 4 mA. The Loop Leader+
mA output should now be close to 4 mA. Enter
the actual value read by the digital mA meter
on the second line of the display and press
Enter.
3. The display will show 20 mA. The Loop
Leader+ mA output should now be close to
20 mA. Enter the actual value read by the
digital mA meter on the second line of the
display and press Enter.
4. The Loop Leader+ will now calculate the
calibration factors and store them.
5. Press Menu to exit.
Enabling the Dual-Scale Feature (PV2)
Dual-Scale Mode
Top Display: Toggling Between Process Variable and Units
Bottom Display: Toggling Between Process Variable
(in different scale) and Different Units
For some level applications, such as displaying the
height and volume of a tank, a second PV can be
enabled which can be scaled to display a different
value based on the same 4-20 mA input. This is
accomplished by enabling the dual-scale feature
(PV2).
When the dual-scale feature is enabled, additional
menus will be displayed to allow for the programming
of the second PV. The input menu will display PV1
and PV2 for scaling and the display menu will allow
both PVs to be displayed on either line, for example.
See Display Functions & Messages on page 29 for
additional information on where additional dual-scale
specific menus will appear.
PV2 must be enabled to use the Round Horizontal
Tank feature. See Round Horizontal Tank
Linearization (RH TANK) on page 59.
Enabling or Disabling the Backlight (BACKLITE)
The backlight may be enabled or disabled using the
Backlight menu. The backlight is enabled by default,
but the input must be wired appropriately for the backlight to function. The backlight must be powered by an
external power source. See Wiring Diagrams on page
24. The voltage drop is the same if the backlight is not
wired or if it is disabled in the System menu.
Viewing System Information (INFO)
System information, such as software (firmware)

Calibrating the Internal mA Reference (ICAL)
The meter is factory calibrated prior to shipment to display
0.00 to 100.00, which corresponds to the 4-20 mA input.
The calibration equipment is traceable to NIST standards.
The use of calibrated signal sources is necessary to
calibrate the internal source of the meter. The meter’s
internal source is what allows the user to scale the
meter without applying a signal.
Check calibration of the meter at least every
12 months.
Note: Allow the meter to warm up for at least 15 minutes
before performing the internal source calibration procedure.
The Internal Calibration menu is part of the Advanced

Meter Operation
The meter is equipped with four buttons behind the
lower panel door used for operation of the meter.
Three buttons labeled F1, F2, and F3 can be
programmed as function keys to perform a variety of
meter functions with a simple push of a button. These
include operation of the tare function, resetting the
tare, resetting the meter’s relays or open collectors,
starting and stopping timers, and displaying max/min
values. See Function Keys & Digital Input Available
Settings on page 63 for a complete list of settings
available.
A digital input is available on the meter and it may
function in a similar fashion as the function keys to
allow remote operation of a single task.
The max & min readings (peak & valley) reached by
the process can be displayed either continuously by
assigning it to a display line in the Display menu, or
momentarily by pressing the F1 key (default) or
assign it to any of the other function key or the digital
input.
The relay information menu shows runtime and cycle

executing their assigned function. See Enabling the
Function Key Hint Feature (HINT) on page 64.
Digital Input Operation
A digital input is standard on the meter. This digital
input is programmed identically to function keys F1,
F2, and F3. The input is triggered with a contact
closure between DI+ and DI-, or with an active low
signal. During operation, the digital input operates
according to the way it has been programmed in the
Advanced Features – User menu.

Runtime & Cycle Count (INFO)
The relay information menu shows runtime and cycle
count for each relay. These values may be cleared at
any time by selecting the Clear option (CLEAR?). If
the cycle count or runtime values need to be changed
on a frequent basis, it would be convenient to set up a
front panel button or the digital input to simplify this
process.
Note: See the menu tree under Solid-State Relay Outputs
(RELAY) on page 46 for complete menu structure on this
feature.

Changing Engineering Units
During operation of the meter, it is possible to change
the display units within the selected unit class without
the need to re-scale the meter. The UNITS menu in the
DISPLAY menu allows the unit of measure to be
changed (e.g. from gallons/second (GAL/s) to
liters/second (L/s)) and the meter will automatically
convert the display values to the new unit of measure.
If entering a custom unit (CUSTOM), a custom
conversion factor will need to be entered. See
Changing the Engineering Units (UNITS) on page 37.

Troubleshooting
This product is a highly sophisticated instrument with
an extensive list of features and capabilities. If the
front panel buttons are used to program the meter, it
can be a difficult task to keep everything straight. That
is why we strongly recommend the use of the free
MeterView XL software for all programming activities.
A cable is provided to use the MeterView XL software
for programming the meter.
If you have programmed the meter with the front
panel buttons and it is not working as intended, try
re-programming the meter using the MeterView XL
software.
Reset Meter to Factory Defaults
When the parameters have been changed in a way
that is difficult to determine what’s happening, it might
be better to start the setup process from the factory
defaults. This can be accomplished using MeterView
XL software or with the front panel buttons.
To load factory defaults:
1. Press the Menu button to enter
Programming Mode.
2. Press the Right-Arrow button twice and
press Enter to access the Advanced menu.
3. Press the Up-Arrow button and press Enter
to access the System menu.
4. Press the Right-Arrow button and press
Enter to access the Default menu.
5. Press Enter twice in quick succession. The
meter will load default settings and restart.
Determining Software Version
To determine the software (firmware) version of a
meter:
1. Press the Menu button to enter
Programming Mode.
2. Press the Up-Arrow button twice and press
Enter to access the Advanced menu.
3. Press the Up-Arrow button and press Enter
to access the System menu.
4. Press the Up-Arrow button twice and press
Enter to access the Info menu.
5. Press the Right-Arrow button to cycle
through the meter information. When done,
press the Menu button to return to the
previous menu or press & hold Menu to exit
to Run mode.

Troubleshooting Tips
Certain sequences of events can cause unexpected results. To solve these issues, it is best to start fresh from factory
defaults and use the manual as a step by step programming guide, rather than a random approach to programming.
See Reset Meter to Factory Defaults on page 68 for details on resetting the meter to factory defaults. In addition, for
best results, we recommend using the free MeterView XL software for all programming needs.
