FREE MeterView Pro Programming Software

The meter can be powered from the Micro USB connection. When using the Micro USB connection, DO NOT apply AC or DC power to the meter.

The easiest and quickest way to program your PROVU meter is to use the FREE MeterView Pro programming software. This software is loaded into the meter and connects and installs directly to your PC with a USB cable. We recommend that the first thing you do after taking the meter out of the box is connect the PROVU to your PC with the provided USB cable – do not use a different cable. DO NOT apply AC or DC power to the meter while your PC is connected to the meter as it will disrupt the USB

connection. You don’t even have to apply an input

signal. MeterView Pro programming software is intuitive, and

most customers can get their meter programmed as they like without even looking in the manual.

In addition to programming, the software may be used for:

• Monitoring

• Datalogging using your PC

• Generating and saving programming files for

later use

Once your meter is programmed the way you want it, you can wire it up for your application per the instructions in this manual and install it. If you find that you need to make adjustments to the programming after the meter is installed, you can use the front panel buttons and the instructions in this manual to do so.

The PROVU PD6100 is a multipurpose, easy-to-use digital strain gauge & load cell meter ideal for weighing and force measurement applications. Its superluminous LED digits make it easily readable in smoke, dust, fog, and, with the optional SunBright display, even direct sunlight.

It accepts mV input signals up to 300 mV. With a max current of 350 mA at 10 V, it can support up to twelve

(12) 350 Ω load cells (minimum load resistance of

28 Ω), making it ideal for multipoint weight

measurement applications. The mV input can be scaled to display the process in two different scales; for example, pounds on display line 1 and gallons on line 2. Three of the front panel buttons can be custom-programmed for a specific operation.

The basic model includes an isolated 5 or 10VDC Sensor power supply that can be used to power the input Sensor or 24 VDC for other devices. An additional isolated 24 VDC power supply is included with the 4-20 mA output option. A digital input (F4) and micro USB port are standard on the meter.

A fully loaded PD6100 meter has the following: four SPDT relays, 4-20 mA output, one 10 VDC sensor excitation, and one 24 VDC power supply. The PD6100 capabilities may be enhanced by adding the following external expansion modules: four SPST relays –creating an eight-relay process meter, two digital I/O modules with four inputs and four outputs each, and RS-232 or RS-485 communication adapters.

The eight relays can be used for alarm indication or process control such as pump alternation control. The 4-20 mA isolated output, Modbus RTU serial communications, and digital I/O options make the PD6100 an excellent addition to any system.

Instruction Manual

Shunt Calibration

The PD6100 is equipped with a means of simulating strain in a strain gauge bridge circuit, via a shunt resistor included inside the meter. This technique is

performed by enabling the “shunt resistor” switch

(switch 5), which in turn shunts one leg of a connected strain bridge with a predetermined resistive load (60.4k). This technique can be used as a means of verifying instrumentation by simulating a physical input. With no load connected, the enabling of the shunt resistor (switch 5) will simulate approximately a 70% F.S. load in the case of a 350Ω Strain Bridge.

Figure 19. Shunt Resistor

Modbus RTU Serial Communications

Serial communications connection is made to an RJ45 connector labeled M-LINK. Use the PDA1232 for RS-232 interfacing or the PDA1485 for RS-485 interfacing. The same port is used for interfacing with all expansion modules (e.g. external relays, digital I/O).

Relay Connections

Relay connections are made to two six-terminal connectors labeled RELAY1 – RELAY4. Each relay’s C terminal is common only to the normally open (NO) and normally closed (NC) contacts of the

corresponding relay. The relays’ C terminals should

not be confused with the COM (common) terminal of the INPUT SIGNAL connector.

Figure 20. Relay Connections

Switching Inductive Loads

The use of snubbers to suppress electrical noise is strongly recommended when switching inductive

loads to prevent disrupting the microprocessor’s

operation. The snubbers also prolong the life of the relay contacts. Suppression can be obtained with resistor-capacitor (RC) networks assembled by the user or purchased as complete assemblies. Refer to the following circuits for RC network assembly and installation:

Figure 21. AC and DC Loads Protection

Choose R and C as follows: R: 0.5 to 1 Ω for each volt across the contacts C: 0.5 to 1 µF for each amp through closed contacts

Notes:

1. Use capacitors rated for 250 VAC.

2. RC networks may affect load release time of solenoid loads. Check to confirm proper operation.

3. Install the RC network at the meter's relay screw terminals. An RC network may also be installed across the load. Experiment for best results.

Use a diode with a reverse breakdown voltage two to three times the circuit voltage and forward current at least as large as the load current.

Figure 22. Low Voltage DC Loads Protection

RC Networks (Snubbers) Available from Precision Digital

RC networks are available from Precision Digital and should be applied to each relay contact switching an inductive load. Part number: PDX6901.

Note: Relays are de-rated to 1/14th HP (50 watts) with an inductive load.

External Relays & Digital I/O Connections

The relay and the digital I/O expansion modules PDA1004 & PDA1044 are connected to the meter using a CAT5 cable provided with each module. The two RJ45 connectors on the expansion modules are identical and interchangeable; they are used to connect additional modules to the system.

Note: The jumper located between the RJ45

connectors of the PDA1044 must be removed on the second digital I/O module in order for the system to recognize it as module #2.

• DO NOT connect or disconnect the expansion modules with the power on! More detailed instructions are provided with each optional expansion module.

Interlock Relay Feature

As the name implies, the interlock relay feature reassigns one, or more, alarm/control relays for use as interlock relay(s). Interlock contact(s) are wired to digital input(s) and activate the interlock relay. This feature is enabled by configuring the relay, and the corresponding digital input(s), see Setting Up the Interlock Relay (Force On) Feature on page 34.

In the example below, an Interlock Contact switch is connected to a digital input, which will be used to force on (energize) the Interlock Relay. The Interlock Relay and the Control Relay are connected in series with the load.

• When the Interlock Contact is closed (safe), the Interlock Relay energizes, allowing power to flow to the Control Relay; the corresponding front panel LED is on.

• When the Interlock Contact is open, the corresponding front panel LED flashes (locked out), the Interlock Relay is de-energized, preventing power from flowing to the Control Relay and the load.

PROVU™ PD6100 Strain Gauge, Load Cell, and mV Meter

Instruction Manual

Setting the Input Signal (Input)

Enter the Input menu to set up the input polarity, range, ratiometric operation, and dual-scale feature.

The meter is capable of accepting any signal from 250 to 250 mV in bipolar mode or up to 300 mV in unipolar mode.

After selecting “Yes” or “No” for ratio, d-SCAL is displayed. Selecting “Yes” enables the dual-scale feature, allowing scaling of the same input in two different scales (for PV1 & PV2) or displaying the percentage of PV1.

Input Polarity Selection (PoLAR)

Select unipolar operation for inputs in ranges from 0 to 300 mV and select bipolar operation for inputs in ranges from -250 mV to +250 mV. This setting determines the selectable ranges for the millivolt input.

NOTE: Refer to Switch Configuration on page 14 for proper configuration switch positioning.

Range Selection (RANGE)

This menu is used to select the input range. The selections listed are determined by the Polarity setting.

Unipolar mode: 0-15 mV, 0-30 mV, 0-150 mV, 0-300 mV

Bipolar mode: ±15 mV, ±25 mV, ±150 mV, ±250 mV

NOTE: Refer to Switch Configuration on page 14 for proper configuration switch positioning.

Ratiometric Operation (ratio)

Ratiometric operation corrects the measured strain gauge signal for up to ±5% variation of either the internal or external excitation power supply. In order to use the ratiometric operation, the ratiometric operation menu must be set to yes (YES).

Dual-Scale (d-sCal)

The mV input can be displayed in two different scales, by enabling the dual-scale feature in the Setup-Input menu. See Dual-Scale (d-sCal) on page 23.

To enable the dual-scale feature you must select d-SCAL in the Input selection menu.

Setting the Display Units (units)

Enter the pre-defined engineering unit or custom unit. The pre-defined units have automatic conversion factors. This unit will be displayed if d unit is selected as the lower display parameter. See Setting the Display Parameter & Intensity (dsplay) flow chart on page 26 to access the display menu to show the unit on the lower display.

The custom unit may also be used to enter a display tag.

Pre-defined engineering units: lb, kg, ounce, gram, ton (short), tonne (metric ton). The meter converts the reading according to the unit selected (e.g. 100.00 lb = 45.36 kg = 45359.2 g = 1600 oz).

Unit Conversions: After scaling values in the Scale menu have been entered during setup, automatic unit conversions are done when switching from any standard unit to any other standard unit during future changes of the Units menu.

Once a standard unit has been selected in the units menu, the user must then set their scaling values for that unit (under the setup menu) in order for that unit's conversion factor to take effect. Otherwise, the meter will allow the user to freely switch between standard unit selections, without applying a conversion factor.

Note that if the dual-scale feature is selected in the Setup menu, both PV1 and PV2 will be converted from the original standard unit to the new standard unit. A scaled PV not scaled for the selected units must be reprogrammed. Example: If PV 1 is scaled for pounds, and PV 2 scaled for gallons; if the units selection is changed from Lb to ounce, PV 2 will need to re-scaled manually back to gallons.

Note: PV1 and PV2 may use different standard units as starting points, however the user must select the unit and complete scaling for both PV1 and PV2 individually. For example, set PV1 equal to "Lbs" and complete the scaling for PV1 only. PV1 is now reading in Lbs. Then, change the units for PV2 to be "Kg" and complete the scaling for PV2.

Notes: Degree symbol represented by (<) if programming with MeterView Pro. The letters “m” and “w” use two 7-segment LEDs each; when selected the characters to the right are shifted one position. Press and hold up arrow to auto-scroll the characters in the display.

Setting the Decimal Point (dEc pt)

The decimal point may be set with up to five 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 leftmost position.

Pressing the Up arrow moves the decimal point to the left. If the dual-scale feature is selected, the decimal point

selections for PV1 & PV2 are enabled.

Programming the Meter (prog)

The meter may either be scaled (SCALE) without applying an input or calibrated (Cal) by applying an input. The meter comes factory calibrated to NIST standards to read in millivolts, so for initial setup, it is recommended to use the (SCALE) function.

For strain gauge and load cell applications it is recommended to calibrate the meter using the sensor as the input and with ratiometric operation enabled to compensate for small variation in the excitation voltage.

The PD6100 is a single input meter with dual-scale capability. If the dual-scale feature is selected in the Setup menu, the Scale 1 and Scale 2 menus are enabled for PV1 & PV2 respectively.

The process inputs may be calibrated or scaled to any display value within the range of the meter.

Instruction Manual

Calibrating the Meter with Strain Gauge/Load Cell (Cal)

To scale the meter without a signal source, refer to

Scaling the Meter (SCALE) on page 25.

The meter can be calibrated to display the process variable in engineering units by applying the appropriate input signal and following the calibration procedure.

The use of a calibrated signal source is strongly recommended to calibrate the meter.

Warm up the meter for at least 15 minutes before performing calibration to ensure specified accuracy.

Multi-Point Calibration & Scaling

The meter is set up at the factory for 2-point linear calibration. The number of points for multi-point calibration/scaling is set up in the Advanced Features menu. Up to 32 linearization points may be selected for PV1 and up to 8 linearization points may be selected for PV2. See Multi-Point Linearization (Linear) on page 38 for details.

Scaling the Meter (SCALE)

The strain gauge input (e.g. 0-100 mV) can be scaled to display the process variable in engineering units.

A signal source is not needed to scale the meter; simply program the inputs and corresponding display values.

For instructions on how to program numeric values see Setting Numeric Values on page 22.

Dual-Scale Application

The mV input can be displayed in two different scales, by enabling the dual-scale feature in the Setup Input menu. See Dual-Scale (d-sCal) on page 23.

To enable the dual-scale feature you must select it in the Input selection menu. See Setting the Input Signal (Input) on page 23 for details.

Scaling the Input for PV1 (SCAL 1)

Scaling the Input for PV2 (SCAL 2)

Error Message (Error)

An error message indicates that the calibration or scaling process was not successful.

After the error message is displayed, the meter reverts to input 2 during calibration or scaling and to input 1 during internal calibration, 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. Wrong signal selection in Setup menu.

3. Minimum input span requirements not maintained.

4. Input 1 signal inadvertently applied to calibrate input 2.

Minimum Input Span

The minimum input span is the minimum difference between input 1 and input 2 signals required to complete the calibration or scaling of the meter.

Programming Set and Reset Points

High alarm indication: program set point above reset point.

Low alarm indication: program set point below reset point.

The deadband is determined by the difference between set and reset points. Minimum deadband is one display count. If the set and reset points are programmed with the same value, the relay will reset one count below the set point.

Note: Changes are not saved until the reset point has been accepted.

Setting Fail-Safe Operation

In fail-safe mode of operation, the relay coil is energized when the process variable is within safe limits and the relay coil is de-energized when the alarm condition exists. The fail-safe operation is set independently for each relay. Select on to enable or select off to disable fail-safe operation.

Programming Time Delay

The On and Off time delays may be programmed for each relay between 0 and 999.9 seconds. The relays will transfer only after the condition has been maintained for the corresponding time delay.

The On time delay is associated with the set point. The Off time delay is associated with the reset point.

Relay and Alarm Operation Diagrams

The following graphs illustrate the operation of the relays, status LEDs, and ACK button.

High Alarm Operation (Set > Reset)

For Manual reset mode, ACK can be pressed anytime to turn "off" relay. To detect a new alarm condition, the signal must go below the set point, and then go above it.

PROVU™ PD6100 Strain Gauge, Load Cell, and mV Meter

Instruction Manual

Low Alarm Operation (Set < Reset)

For Manual reset mode, ACK can be pressed anytime to turn "off" relay. For relay to turn back “on”, signal must go above set point and then go below it.

High Alarm with Fail-Safe Operation (Set > Reset)

Note: Relay coil is energized in non-alarm condition. In case of power failure, relay will go to alarm state.

Low Alarm with Fail-Safe Operation (Set < Reset)

Note: Relay coil is energized in non-alarm condition. In case of power failure, relay will go to alarm state.

Time Delay Operation

The following graphs show the operation of the time delay function.

When the signal crosses the set point, the On time delay timer starts and the relay trips when the time delay has elapsed. If the signal drops below the set point (high alarm) before the time delay has elapsed, the On time delay timer resets and the relay does not change state. The same principle applies to the Off time delay.

Note: If “Automatic or Manual (A-mAn)” reset mode is selected, the LED follows the reset point and not the relay state when the relay is acknowledged.

Relay Operation Details

Overview

The relay capabilities of the meter expand its usefulness beyond simple indication to provide users with alarm and control functions. These capabilities include front panel alarm status LEDs as well as either 2 or 4 optional internal relays and/or 4 external relays expansion module. Typical applications include high or low force, level, or pressure alarms, control applications such as simple on/off control, and relay alternation control for up to 8 pumps. There are four basic ways the relays can be used:

1. High or Low Alarms with Latching or NonLatching Relays

2. Simple On/Off Control with 100% Adjustable Deadband

3. Sampling (Based on Time)

4. Alternation Control for up to 8 Pumps

Relays Auto Initialization

When power is applied to the meter, the front panel LEDs and alarm relays will reflect the state of the input to the meter. The following table indicates how the alarm LEDs and relays will react on power-up based on the set and reset points.

Fail-Safe Operation

The following table indicates how the relays behave based on the fail-safe selection for each relay:

Fail-Safe Selection

Open

Relays go to nonalarm state

Closed

Open

Closed

Relays go to alarm state

Note: NO = Normally Open, NC = Normally Closed.

This refers to the condition of the relay contacts when the power to the meter is off.

Front Panel LEDs

The LEDs on the front panel provide status indication for the following:

LED

Status

LED

Status

Alarm 1

5 Alarm 5

Alarm 2

6 Alarm 6

Alarm 3

7 Alarm 7

Alarm 4

8 Alarm 8

The meter is supplied with four alarm points that include front panel LEDs to indicate alarm conditions. This standard feature is particularly useful for alarm applications that require visual-only indication. The LEDs are controlled by the set and reset points programmed by the user. When the display reaches a set point for a high or low alarm, the corresponding alarm LED will turn on. When the display returns to the reset point the LED will go off. The front panel LEDs respond differently for latching and non-latching relays.

For non-latching relays, the LED is always off during normal condition and always on during alarm condition, regardless of the state of the relay (e.g. Relay acknowledged after alarm condition).

For latching relays, the alarm LEDs reflect the status of the relays, regardless of the alarm condition. The following tables illustrate how the alarm LEDs function in relation to the relays and the acknowledge button (Default: F3 key assigned to ACK).

Latching and Non-Latching Relay Operation

The relays can be set up for latching (manual reset) or non-latching (automatic reset) operation.

Non-Latching Relay (Auto)

In this application, the meter is set up for automatic reset (non-latching relay). Acknowledging the alarm while it is still present has no effect on either the LED or the relay. When the alarm finally goes away, the relay automatically resets and the LED also goes off.

Non-Latching Relay with Manual Reset (A-nman)

In this application, the meter is set up for automatic and manual reset at any time (non-latching relay). The LED and the relay automatically reset when the meter returns to the normal condition.

In addition, the relay can be manually reset while the alarm condition still exists, but the LED will stay on until the meter returns to the normal condition.

Notice that the LED remains on, even after the meter returns to the normal condition. This is because, for latching relays, the alarm LED reflects the status of the relay, regardless of the alarm condition.

Acknowledging Relays

There are three ways to acknowledge relays programmed for manual reset:

1. Via the programmable front panel function keys F1-F3 (Example: F3 assigned to ACK).

2. Remotely via a normally open pushbutton wired to the F4 terminal at the rear of the instrument.

3. One of the digital inputs and the +5 V terminals on the digital I/O expansion module.

When the ACK button or the assigned digital input is closed, all relays programmed for manual reset are acknowledged.

Pump Alternation Control Applications (Altern)

For pump control applications where two or more similar pumps are used to control the level of a tank, it is desirable to have all the pumps operate alternately. This prevents excessive wear and overheating of one pump over the lack of use of the other pumps.

Up to 8 relays can be set up to alternate every time an on/off pump cycle is completed. The set points and reset points can be programmed, so that the first pump on is the first pump off.

Application #1: Pump Alternation Using Relays 1 & 2

1. Relays 1 and 2 are set up for pump alternation.

2. Relays 3 and 4 are set up for low and high alarm indication.

2. The next time level reaches 30.000, pump #2 turns on, when level drops below 10.000 pump #2 turns off.

3. If the level doesn’t reach 35.000 pump #1 and pump #2 will be operating alternately.

4. If pump #1 cannot keep the level below 35.000 pump #2 will turn on at 35.000, then as the level drops to 10.000 pump #1 turns off, pump #2 is still running and shuts off below 5.000.

5. Notice that with the set and reset points of pump #2 outside the range of pump #1, the first pump on is the first pump to go off. This is true for up to 8 alternating pumps, if setup accordingly.

6. Relay #3 will go into alarm if the level drops below 4.000 and relay #4 will go into alarm if the level exceeds 40.000.

7. Adding the 4 external relays expansion module allows using the 4 SPDT internal relays for pump alternation and the 4 SPST external relays for high, high-high, low, and low-low alarm indication.

Setting Up the Interlock Relay (Force On) Feature

Relays 1-4 can be set up as interlock relays. To set up the relays for the interlock feature:

1. Access the Setup – Relay – Action menu and set the action to off.

2. In the Advanced features – User menu program

any of the digital inputs to Force On any of the internal relays (1-4).

3. Connect a switch or dry contact between the +5V

terminal and the corresponding digital input (dI-1 to dI-4) terminal.

Interlock Relay Operation Example

Relays 1 & 2 are configured to energize (their front panel LEDs are steady on) when SW1 & SW2 switches (above) are closed. If the contacts to these digital inputs are opened, the corresponding front panel LEDs flash indicating this condition. The processes being controlled by the interlock relay will stop, and will re-start only after the interlock relay is re-activated by the digital inputs (switches).

Note: If multiple digital inputs are assigned to the same relay, then the corresponding logic is (AND) – i.e. both switches must be closed to activate the relay.

Instruction Manual

Tare Menu (Tare)

The Tare menu is used to select the tare mode. There are three modes of operation: Capture Tare, Programmable Tare, and Off.

Capture Tare: Pressing the Tare key zeroes the

display and the “T” indicator flashes indicating that

tare is applied to the reading (e.g. Net weight). Programmable Tare: Program a known value to be

subtracted from the display value to obtain the net value. Pressing Reset tare clears the tare value to zero. Programmable Tare will not tare negative PVs. Use Capture Tare for negative PVs.

Off: Tare function is disabled and pressing Tare key has no effect.

Tare Functionality (tare)

The tare function zeroes out the display. In the case of scale weight, tare is used to eliminate container weight and provide net weight readings.

Manual Control Menu (Contrl)

The Manual Control menu is used to control the 4-20 mA analog output and the relays manually, ignoring the input. Each relay and analog output can be programmed independently for manual control. Selecting automatic control sets all relays and analog output for automatic operation.

Advanced Features Menu

To simplify the setup process, functions not needed for most applications are located in the Advanced Features menu.

Press and hold the Menu button for three seconds to access the advanced features of the meter.

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. The filter level determines the length of time over which the signal is averaged. The filter level can be set between 2 and 199. 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 zero disables the filter function.

Noise Filter Bypass (bypass)

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.

Rounding Feature (round)

The rounding feature is used to give the user a steadier display with fluctuating signals. Rounding is used in addition to the filter function.

Rounding causes the display to round to the nearest value according to the rounding selected. This setting affects the last two digits, regardless of decimal point position. See examples below:

Instruction Manual

Modbus RTU Serial Communications (serial)

The meter is equipped with serial communications capability as a standard feature using Modbus RTU Serial Communication Protocol.

The meter may be connected to a PC for initial configuration via the onboard micro USB connection. For ongoing digital communications with a computer or other data terminal equipment, an RS-232, or RS-485 option is required; see Ordering Information on page 6 for details.

• DO NOT connect any equipment other than

Precision Digital’s expansion modules, cables, or

meters to the RJ45 M LINK connector. Otherwise damage will occur to the equipment and the meter.

Select Menu (SElect)

The Select menu is used to select the input signal conditioner applied to the input (linear), low-value cutoff, Auto-zero, and analog output programming.

The multi-point linearization is part of the linear function selection.

Input Signal Conditioning (Functn)

The Function menu is used to select the input signal conditioner applied to the input: linear. The 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.

When using more than one meter in a multi-drop mode, each meter must be provided with its own unique address. The meter address (Slave ID) may be programmed between 1 and 247. The transmit delay may be set between 0 and 199 ms. The parity can be set to even, odd, or none with 1 or 2 stop bits.

Multi-Point Linearization (Linear)

Meters are set up at the factory for linear function with 2-point linearization. Up to 32 linearization points can be selected for PV under the linear function. The multi-point linearization can be used to linearize the display for non-linear signals.

If the dual-scale Level feature has been selected, the menus for PV1 & PV2 are enabled. PV2 can be programmed with up to 8 linearization points.

PROVU™ PD6100 Strain Gauge, Load Cell, and mV Meter

Instruction Manual

Auto-Zero (Auto 0)

Auto-zero corrects for drift that can occur over time that causes the input signal to slowly change. The meter will continue to read zero despite slow and small changes to the input signal. The auto-zero value represents the percent of full scale drift that the meter will correct.

Under normal circumstances, when the signal increases quickly, by an amount greater than the auto-zero percent of full scale, the value will not be adjusted for. Slow signal changes that occur over time at increments less than the auto-zero value, will not register on the meter (example: dust on a load cell or sensor drift over time).

Low-Value Cutoff (CutofF)

The low-value cutoff feature allows the meter to be programmed so that below a certain value, the meter always displays zero.

The cutoff value may be programmed from 0 to

999999. The meter will display zero below the cutoff value. Programming the cutoff value to zero disables the cutoff feature.

Analog Output Programming (AoutPr)

The Analog Output Programming menu is used to program the behavior of the 4-20 mA output. The following parameters and functions are programmed in this menu:

1. Source: Source for generating the 4-20 mA output (e.g. PV)

2. Overrange: Analog output value with display in overrange condition

3. Underrange: Analog output value with display in underrange condition

4. Max: Maximum analog output value allowed regardless of input

5. Min: Minimum analog output value allowed regardless of input

6. Calibrate: Calibrate the internal 4-20 mA source reference used to scale the 4-20 mA output

Analog Output Source

The source for generating the 4-20 mA output may be assigned to the process variable, maximum or minimum value reached by the process, one of the set points, or the Modbus PV input.

Analog Output Calibration

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.

Analog Output Calibration Procedure

1. Wire the PD6100 4-20 mA output to a current loop that includes a power supply (internal or external 12 to 24 VDC), and the mA input on the digital meter. See Figure 23. 4-20 mA Output Connections on page 17 for details.

2. Turn on all devices. Allow for a 15 to 30 minute warm-up.

3. Go to the Advanced Features menu, and navigate to the Analog Output Programming (AoutPr)/Calibration (Calib) menu and press Enter.

4. The display will show 4 nmA. The PD6100 mA output should now be close to 4 mA. Press Enter and the display will show 04.000. Enter the actual value read by the digital mA meter and press Enter.

5. The display will show 20 nmA. The PD6100 mA output should now be close to 20 mA. Press Enter and the display will show 20.000. Enter the actual value read by the digital mA meter and press Enter.

6. The meter will now calculate the calibration factors and store them.

7. Press Menu to exit and return to Run mode.

Instruction Manual

Internal Source Calibration (ICAL)

There is no need to recalibrate the meter when first received from the factory.

The meter is factory calibrated prior to shipment for millivolts with calibration equipment that is certified to NIST standards.

The internal source allows the user to scale the meter without applying a signal.

The use of calibrated signal sources is necessary to perform the internal source calibration of the meter.

Check calibration of the meter at least every 12 months. Each range must be recalibrated separately.

Notes:

1. mV input: If meter is in operation and it is intended to accept only one input range (e.g. 0-30 mV), recalibration of other ranges is not necessary.

2. Strain gauge: If the meter is intended to accept a strain gauge bridge input, it is recommended to use the CAL function with ratiometric compensation turned on.

3. 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 Features menu.

1. Press and hold the Menu button for three seconds to access the advanced features of the meter.

2. Press the Up arrow button to scroll to the Internal calibration menu (ICAL) and press Enter.

3. The meter displays the first input range (15 nmV), press the Up arrow to select any other range (e.g. 100nmV. Press Enter to start the calibration process.

Example of Internal Calibration for 100 mV input range:

4. The meter displays the message “stroff” (strain offset), short the SG+, SG- terminals and press Enter. The low input message is displayed (V lo). Apply the low input signal (e.g. 0.00 mV) and press Enter. The display flashes for a moment while the meter is accepting the low input signal.

5. After the display stops flashing, a number is displayed with the leftmost digit brighter than the rest. The bright digit is the active digit that can be changed by pressing the Up arrow button. Press the Right arrow button to move to the next digit.

6. Set the display value to correspond to the input signal being calibrated; typically 0.00 mV.

7. The display moves to the high input calibration (V Hi). Apply the high input signal and press Enter.

8. Set the display for the high input calibration, in the same way as it was set for the low input calibration, typically 100.00 mV.

The following graphic shows the calibration of the 100 mV input range. The other ranges are calibrated in a similar way.

Tips:

• Low and high input signals can be any valid values within the range of the meter.

• Observe minimum input span requirements between input 1 and input 2.

• Low input should be less than high input signal.

Error Message (error)

An error message indicates that the calibration or scaling process was not successful.

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. Wrong signal selection in Setup menu.

3. Minimum input span requirements not maintained.

Minimum Input Span

The minimum input span is the minimum difference between input 1 and input 2 signals required to complete the calibration or scaling of the meter.

Meter Operation

The meter is capable of accepting any signal from

-250 to 250 mV in bipolar mode, or 0 to 300 mV in unipolar mode, and displaying these signals in engineering units from -99999 to 999999 (e.g. a 0-100 mV signal could be displayed as 0 to 50000). The dual-line display can be customized by the user to operate in such a way as to satisfy a specific application. Typically, display line 1 is used for the process variable; while line 2 is used for engineering units, custom legend, or set point indication.

The input signal can be scaled to display the process in two different scales; for example, line 1 could indicate weight in pounds and line 2 could indicate percent of maximum weight capacity. The meter can also be set up to display the mV input on line 1 and the Modbus input on line 2. The relays and analog output can be programmed to operate from the Modbus PV input if the Modbus input has been assigned to display line 1.

During operation, the meter can be either tared or zeroed. The tare feature is useful for momentarily zeroing out of the display, in the case where there is additional weight than what is intended to be measured (e.g. a bucket on the scale is being filled with material). The meter will display a T to indicate that the display has been tared and taring is resettable via the reset tare operation. The zero feature is useful for permanent zeroing of the meter, in the case where there has been drift in the strain gauge output over time. The zero feature will zero out the display without indication or the ability to reset.

Troubleshooting Tips

This meter 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 may be a difficult task to keep everything straight. That is why we strongly recommend the use of the free MeterView Pro software for all programming activities. A cable is provided with the meter for programming with MeterView Pro software.

If you have programmed the meter with the front panel buttons and it is not working as intended, try re-programming the meter using MeterView Pro software.

Symptom

Check/Action

No display at all

Check power at power connector

Not able to change setup or programming, Locd is displayed

Meter is password-protected, enter correct six-digit password to unlock

Meter does not respond to input change

If a Low Value Cutoff has been programmed, the meter will display zero below that point, regardless of the input – which can appear like the meter is not responding to an input change. Check to make sure the problem is not being caused by an undesired low value flow cutoff value.

Meter displays error message during calibration (Error)

Call Technical Support for assistance.

Note: 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. To reset the meter to factory defaults, see Reset Meter to Factory Defaults on page 43. In addition, for best results, we recommend using the free MeterView Pro software for all programming needs.
