Introduction
These loop-powered 1/8 DIN digital panel 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 dual line display which is typically used to display the process variable on the 5-digit alphanumeric top display and the units of measure or a tag on the 8­digit 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 for clear indica­tion of tags, units, or alarm messages. Further enhancing the display on these instruments is a 20-segment bargraph available on the PD6604 and PD6608 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 drop 1.5 V (4.5 V with backlight), 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 front panel, 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. Finally, there are intrinsically safe and nonincendive versions of these instruments that can be installed in hazard­ous areas. Free, PC-based, MeterView XL software that con­nects to the meter via a micro USB cable is available for programming and setup of the meters. For more details, see the LIM6602MVXL manual.
All models come equipped with two open collector outputs and a digital input. 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 digital input can be used 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
Informative Display
The Loop Leader’s display provides multiple ways to
help users understand and keep track of their processes. The most obvious is the dual line which typically allows the user to display a numeric value of the process variable on the top line and units and/or a tag on the bottom line. An optional bargraph that includes a numeric value of the percentage the bargraph represents is also available.
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.
Alarm Indication
When an alarm occurs, the Loop Leader's display can be programmed to turn red. It may also be set up to flash an alarm message along with the process variable. The flashing red alarm message 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.

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)
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.
Pump Alternation Example
The following is an example application where the re­lays are programmed for pump alternation.

Relay #2 turns the main pump on at 6000 gallons and turns it off at 1000 gallons.
With the PumpAlternation 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.
Once the level has dropped below the reset points, both relays will turn off.

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.
PD6602 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 PD6602, 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. It is only available for PV2 while the meter is in dual-scale mode.
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.

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 (PD6604/8 Only), 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.
Enabling or Disabling Commas on the Bottom Display (COMMA)
The bottom display is set to show a comma separat­ing the thousands and millions place by default if a numeric value is being displayed. This feature can be disabled or enabled using the Comma menu.

Programming the Outputs (OUTPUT)
Depending on the model purchased, the meter may be available with two open collector outputs, 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 8 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. In addition, for meters without a bargraph an alarm indicator (!) will also display.
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

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.
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 automat- ically 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 relays. Alarm states will be displayed on the meter even if no relay output is physically connected. These may in­clude a red LED backlight, flashing PV value (PV alarm only), and a programmable alarm message. In addition, for meters without a bargraph an alarm indi­cator (!) (only on meters with no bargraph) will also display.

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 on-time 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.

Note: Open Collectors can be used for high and low alarm indication.
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 (ONTIME) 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 Advanced).

Relay #2 turns the main pump on at 6000 gallons and turns it off at 1000 gallons.
With the PumpAlternation 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.
Once the level has dropped below the reset points, both relays will turn off.

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 relay. There are three settings needed to use the function effectively.
1. Assign stopwatch to either top or bottom dis­play line
2. Assign the relay 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 28 & 30 for details how to change the display)
• Relay 1
(see pages 31 & 34 how to change Open Col­lector and or Solid State Relay functionality)
• F3: Start/Stop
(see pages 42 & 43 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.
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 PD6602, 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 lineari- zation 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 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.
MeterView XL showing the linear points setup feature.
Up to 32 points can be selected for PV1 and PV2.
Round Horizontal Tank Linearization (RH TANK)
This function automatically calculates the volume in a round horizontal tank with flat ends. It is only available for PV2 while the meter is in dual-scale mode.
For instructions on how to enable PV2 see Changing System Settings (SYSTEM) on page 44.
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.
See Changing the Engineering Units (UNITS) on page 29 and Available Unit Classes and Units on page 28 for a list of available volume units. There is no need to enter scaling values.

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 27 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 27.
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
3. Available Unit Classes and Units on page 28.
4. The meter displays INP 1. Apply a known signal and press Enter. The display will flash while accepting the signal.
5. After the signal is accepted, the meter displays DSP 1. Enter a corresponding display value for the input signal, and press Enter to accept.
6. The meter displays INP 2. Apply a known signal and press Enter. The display will flash while accepting the signal.
7. After the signal is accepted, the meter displays DSP 2. Enter a corresponding display value for the input signal and press Enter to accept.
8. 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. When a password has been enabled, the lock icon will display in the lower right of the display (PD6602/6 only). For instructions on how to program numeric values see Setting Nu- meric Values on page 27.
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.

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.

Enabling the Function Key Hint Feature (HINT)
Enabling the function key hint feature will cause a hint message to be displayed when pressing the F1, F2, or F3 function keys. This text gives a brief description of what the button is programmed to do. Pressing that function key a second time will execute that action.
The hint feature does not affect the digital input (DI) which is intended for immediate execution.
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 23 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 40.
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. See Wiring Diagrams on page 20. 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) number and version, model number, and system tag, may be viewed in the INFO menu. Press the Right Arrow button to cycle through all available meter information. Press Menu to go back to the previous menu.

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 menu. Internal Calibration is performed as follows:
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 and press Enter to access the ICAL menu.
5. The meter displays low input current message (4.000 mA). Apply a 4 mA signal and press Enter. The display flashes for a moment while the meter is accepting the low input signal.
6. After the display stops flashing, the display
moves to the high input calibration (20.000 mA). Apply the high input signal and press Enter. The display will flash again while the meter is accepting the high input signal.

Meter Operation
The meter can accept a 4-20 mA current signal and display it in engineering units from -9999 to 99999 on the top display or from -9,999,999 to 99,999,999 (with commas, if desired) on the bottom display. For example, a 4-20 mA signal could be displayed as
-50.00 to 50.00 on the top display. The dual-line display can be customized to display the
process variable and other parameters in a wide vari­ety of ways. Typically, the top display is used for the process variable while the bottom display is used for engineering units, custom tag, or process variable percentage of full scale.
The 4-20 mA input can be scaled to display the pro­cess in two different scales; for example: with PV2 en­abled, the top display could indicate level in feet and the bottom display could indicate the volume in gal­lons.

Function Keys Operation
During operation, the programmable function keys op­erate according to the way they have been pro­grammed in the Advanced Features – User menu. The table under Front Panel Buttons Operation shows the factory default settings for F1, F2, and F3.
A hint message may be enabled to provide a descrip­tion of what each function key does prior to executing their assigned function. See Enabling the Function Key Hint Feature (HINT) on page 44.
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.
Maximum/Minimum Readings
The max & min readings (peak & valley) reached by the process can be displayed either continuously or momentarily.
Display momentarily by pressing the F1 key (default) or assigning to any of the other function keys or to the digital input in the User menu.
Display continuously by pressing the Enter button while the max/min is being displayed to lock the dis­play. Press Enter again to unlock.
Any of the F1-F3 function keys (buttons) and the digi­tal input can be programmed to reset the max & min readings.

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 34 for complete menu
structure on this feature.
Meter displaying the amount of time a relay has been activated
Meter displaying the number of times a relay has cycled
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

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 48 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.
Symptom
Check/Action
No display at all
1. Check that the 4-20 mA current loop is providing at least 3.5 mA to the meter.
