Introduction

The PROVU® PD6400 is a multipurpose, easy-to-use high voltage and current input meter ideal for measuring direct voltage and current or the output from voltage shunts and current transformers. It has one 0-300 VAC or VDC voltage input and one 0-5 AAC or ADC current input. The meter may be used with a single voltage or current input, or to measure both simultaneously. A math channel P calculates apparent power as the product of the voltage and current inputs.

The PD6400 can display voltage, current, and apparent power. The dual line display can display any two parameters simultaneously, or can alternate between any parameters as well as their programmable units and tags. Its superluminous LED digits make it easily readable in smoke, dust, fog, and, with the optional SunBright® display, even direct sunlight.

A fully loaded PD6400 meter has the following: four SPDT relays, 4-20 mA output, and a 24 VDC power supply. The PD6400 capabilities may be enhanced by adding the following external expansion modules: four SPST relays; creating an eight-relay meter, two digital I/O modules with four inputs and four outputs each, serial communication adapters for use with MeterView Pro or Modbus RTU, and a dual 4-20 mA expansion module; for a total of three 4-20 mA analog outputs.

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.

Relay Connections

Relay connections are made to two six-terminal connectors labeled RELAY1 – RELAY4 on Figure 5. 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 15. Relay Connections

Switching Inductive Loads

The use of suppressors (snubbers) is strongly recommended when switching inductive loads to prevent disrupting the microprocessor’s operation. The suppressors 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 16. 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.

Figure 17. Low Voltage DC Loads Protection

RC Networks 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.

Warning!

Do not connect or disconnect the expansion modules with the power on! More detailed instructions are provided with each optional expansion module.

External Relay, Analog Output, & Digital I/O Connections

The relay, analog out, and digital I/O expansion modules PDA1004, PDA1011, and 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.

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 trigger the interlock relay. This feature is enabled by configuring the relay, and relative digital input(s) (see page 33). In one example, dry interlock contacts are connected in series to one digital input which will be used to force on (energize) the assigned interlock power relay when all interlock contacts are closed (safe). The interlock relay front panel LED flashes when locked out. The interlock relay would be wired in-series with the load (N/O contact). See below.

Scaling the Meter for Channel A (SCal-A)

Scaling the Meter for Channel V (SCal-v)

Setting the Input Calibration (InCal)

It is very important to read the following information, before proceeding to program the meter:

• The meter is factory calibrated prior to shipment to read in amps and volts. The calibration equipment is certified to NIST standards.

• Use the Scale menu to scale the current and voltage inputs. A calibrated signal source is not needed to scale the meter.

• Use the Calibrate menu to apply a signal from a calibrator or other live signal source.

The Program menu contains the Scale and the Calibrate menus for channels A & V. The process inputs may be calibrated or scaled to any display value within the range of the meter.

Note: The Scale and Calibrate functions are exclusive of each other. The meter uses the last function programmed. Only one of these methods can be employed at a time. The Scale and Calibrate functions can use up to 32 points (default is 2). The number of points should be set in the Advanced Menu under the menu selection prior to scaling and calibration of the meter, see page 40 for details.

Multi-Point Linearization (Linear)

The process inputs may be calibrated or scaled to any display value within the range of the meter. The meter is set up at the factory for 2-point linear calibration.

Up to 32 linearization points may be selected. See page 40 for details.

Scaling the Meter without a Signal Source

The voltage and current inputs can be scaled to display the process variables in engineering units. A signal source is not needed to scale the meter; simply program the inputs and corresponding display

values.

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.

Calibrating the Meter with External Source

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.

Setting the Relay Action

Operation of the relays is programmed in the Action menu. The relays may be set up for any of the following modes of operation:

1. Automatic reset (non-latching)

2. Automatic + manual reset at any time (non-latching)

3. Latching (manual reset only, at any time)

4. Latching with Clear (manual reset only after alarm condition has cleared)

5. Pump alternation control (automatic reset only, for level applications unrelated to

voltage and current monitoring)

6. Sampling (the relay is activated for a user-specified time)

7. Off (relay state controlled by Interlock feature)

The following graphic shows relay 1 action setup; relay 2-8 are set up in a similar fashion.

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 Action for Loss of Input (Loop Break)

The loop break feature is associated with the current or voltage input. Each relay may be programmed to go to one of the following conditions when the meter detects the loss of the input signal (i.e. < 25 mA):

1. Turn On (Go to alarm condition)

2. Turn Off (Go to non-alarm condition)

3. Ignore (Processed as a low signal condition)

Note: This is not a true loop break condition; if the signal drops below 25 mA, it is interpreted as a “loop

break” condition.

When the signal crosses the set point, the relay trips and the sample time starts. After the sample time has elapsed, the relay resets. The cycle repeats every time the set point is crossed, going up for high alarms and going down for low alarms.

The sample time can be programmed between 0.1 and 5999.9 seconds.

Signal Loss or Loop Break Relay Operation

The following graph shows the loop break relay operation for a high alarm relay.

When the meter detects a break in the current or voltage loop, the relay will go to one of the following selected actions:

1. Turn On (Go to alarm condition)

2. Turn Off (Go to non-alarm condition)

3. Ignore (Processed as a low signal condition)

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 monitoring of high voltages and currents having to do with applications related to generators, voltage monitoring, current monitoring, or detecting locked rotor conditions. There are three basic ways the relays may typically be used:

1. High or Low Alarms with Latching or Non-Latching Relays

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

3. Sampling (Based on Time)

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:

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:

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 visualonly 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 responds 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 reflects 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.

The On and Off terminology does not refer to the status of the relay’s coil, which depends on the fail-safe mode selected.

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 (A-man)

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. The next time an alarm occurs, the operator acknowledges the alarm manually while the alarm condition still exists. This causes the relay to reset, but the LED stays on until the meter returns to the normal condition.

Latching Relay (LatcH)

In this application, the meter is set up for manual reset at any time. Acknowledging the alarm even if the alarm condition is still present resets the relay and turns off the LED.

Latching Relay (Lt-Clr)

In this application, the meter is set up for manual reset only after the signal passes the reset point (alarm condition has cleared). Acknowledging the alarm while it is still present has no effect on either the LED or the relay. When the alarm is acknowledged after it returns to the normal state, the LED and the relay go off. 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.

2. Remotely via a normally open pushbutton wired across one of the digital inputs and the +5 V

terminals on the digital I/O modules, or using the F4 digital input, which is triggered with a contact closure to COM, or with an active low signal (see page 14).

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

Pump Alternation Control Applications (Altern)

Pump alternation control is not recommended when using this meter, as it is used only in voltage and current monitoring applications, and not with rate, total, or batching applications.

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.

For instructions on how to

program numeric values see

Setting Numeric Values, page 20.

Interlock Relay Operation Example

Relays 1 & 2 are configured to energize (their front panel LEDs are off) 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 restart 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 trip the relay.

Scaling the 4-20 mA Analog Output (Aout)

The 4-20 mA analog outputs can be scaled to provide a 4-20 mA signal for any display range selected. To select the channel and source assignments the analog outputs are assigned to, see Analog Output Source on page 41.

No equipment is needed to scale the analog outputs; simply program the display values to the corresponding mA output signal.

The Analog Output menu is used to program the 4-20 mA outputs based on display values.

Reset Menu (reset)

The Reset menu is used to reset the maximum or minimum reading (peak or valley) reached by the process; both may be reset at the same time by selecting “reset high & low” (rst HL).

Control Menu (Contrl)

The 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.

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.

Modbus RTU Serial Communications (serial)

Warning!

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.

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 5 for details.

Note: More detailed instructions are provided with each optional serial communications adapter. Note: Changes made to the Serial menu are initialized after the menu key is pressed or after navigating

through the remainder of the serial parameters (i.e. pass the t-byte parameter).

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.

Changes made to the Serial menu are initialized after the MENU key is pressed or after navigating through the t-byte parameter.

Select Menu (SElect)

The Select menu is used to select the number of linearization points applied to the input for either channel A or V, adder and factor constants applied to the power function P=([I*V]+C)*F, low-flow cutoff, and analog output programming.

Multi-Point Linearization (Linear)

The multi-point linearization can be used to linearize the display for non-linear signals. The Function menu is used to access the Linear menu and select the number of linearization points applied to the input for either Ch-A or Ch-V. Meters are set up at the factory for linear function with 2-point linearization. Up to 32 linearization points can be selected for each channel under the linear function.

Note: After Scale is displayed continue pressing the Enter button until the meter completes the scaling of

the input and display values.

Math Function (math)

Within the Math menu is the power function, P = I*V, available on this meter to calculate the apparent power. This math function is a combination of input channels A and V, and will display when channel P is selected in the Display menu. The actual function, as calculated by the meter, is P = ( [A*V] + C )*F, where C is the adder constant and F is the Factor constant.

Math Constants (Const)

The Math Constants menu is used to set the constants used in channel P math. The math function includes input channel A and V, as well as the adder constant C, and factor constant F.

The Adder constant (C) may be set from -99.999 to 999.999. The Factor constant (F) may be set from 0.001 to 999.999.

Low-Flow Cutoff (CutofF)

The low-flow cutoff feature allows the meter to be programmed so that any noise picked up from nearby transformers or other electric devices that cause an otherwise zero reading to fluctuate always displays zero on the meter.

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

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

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

4. Break: Analog output value when loop break is detected

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

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

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

Page 41

PROVU PD6400 High Voltage and Current Meter Instruction Manual

Analog Output Source

The analog output source can be based on either of the input channels (Ch-A, Ch-V), the power channel (Ch-P), maximum stored value of either input channel (Hi-A, Hi-V), minimum stored value of either input channel (Lo-A, Lo-V), relay set points, or the Modbus 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.

Programmable Function Keys User Menu (user)

The User menu allows the user to assign the front panel function keys F1, F2, and F3, the digital input F4 (a digital input located on the signal input connector), and up to eight additional digital inputs to access most 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.

Up to eight digital outputs can be assigned to a number of actions and functions executed by the meter (i.e. alarms, relay acknowledgement, reset max, min, or max & min, tare, and reset tare). The digital outputs can be used to trigger external alarms or lights to indicate these specific events.

The meter is factory calibrated prior to shipment to read in amps

and volts. The calibration equipment is certified to NIST standards.

Notes:

1. If meter is in operation and it is intended to accept only one input type (e.g. 0-5 AAC or 0-300 VDC), recalibration of other input is not necessary.

2. Allow the meter to warm up for at least 15 minutes before performing the internal calibration procedure.

Internal Calibration (ICAL)

The use of calibrated signal sources is necessary to perform the internal calibration of the meter. Check calibration of the meter at least every 12 months. Each input and input type must be recalibrated

separately.

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. Select channel A (Ch-A) or channel V (Ch-v) and press enter.

4. The meter displays either current calibration (C CAL) or voltage calibration (v CAL) depending on whether channel A (Ch-A) or channel V (Ch-v) is selected. Press Enter to start the calibration process.

Example of Internal Calibration for current input:

5. The meter displays low input current message (C lo). Apply the low input 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, 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.

7. Set the display value to correspond to the input signal being calibrated (e.g. 0 VDC).

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

9. Set the display for the high input calibration, in the same way as it was set for the low input calibration (e.g. 300 VDC).

The graphic above shows the calibration of the current input. The voltage input is calibrated in a similar way.

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.

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 two input channels (A and V) of either current (0-5 AAC/DC) or voltage signals (0-300 VAC/DC) and displaying these signals in engineering units from -99999 to 999999 (e.g. a 15 A signal could be displayed as -50.000 to 50.000).

A power function channel (P) is available to perform the power operation (P = IV) on channel A and V, with adder and factor constants, and display the results. Engineering units or tags may be displayed with these three channels.

The dual-line display can be customized by the user. Typically, display line 1 is used to display the channel V, while line 2 is used to alternate between displaying input channels A and P.

Additionally, the meter can be set up to display any channel on line 1 and a unit or tag on line 2. The relays and analog output can be programmed to operate based on any channel.

During operation, the programmable function keys operate according to the way they have been programmed in the Advanced Features – User menu.

The table above shows the factory default settings for F1, F2, and F3.

F4 Operation

A digital input, F4, 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 to COM, or with an active low signal. During operation, F4 operates according to the way is 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 momentary:

1. Display briefly by assigning to the F1-F3 function keys or to the digital inputs in the User menu.

2. Display continuously by assigning either display to max/min through the Display menu.

Any of the F1-F3 function keys (buttons) and the digital inputs can be programmed to reset the max & min readings. The meters are set at the factory to display the max reading by pressing the Up arrow/F2 button and to use the Right arrow/F1 button to access the Reset menu.

To display max and min channel A reading using function key with factory defaults:

1. Press Up arrow/F2 button to display minimum reading of channel A since the last reset/power-up. The display will then display the maximum reading of channel A since the last reset/power-up.

2. Press the Up arrow/F2 button again to display the minimum reading of channel A since the last reset/power up.

3. To reset max/min press Right arrow/F1 button to access the Reset menu. The max & min displays are reset to actual values.

4. Press Menu to exit max/min display reading.

Troubleshooting

Due to the many features and functions of the meter, it’s possible that the setup of the meter does not agree with what an operator expects to see. If the meter is not working as expected, refer to the Diagnostics menu and consult the recommendations described below.

Diagnostics Menu (diag)

The Diagnostics menu is located in the Advanced Features menu, to access Diagnostics menu see Advanced Features Menu, page 36.

This menu allows the user to test the functionality of all the meter LEDs, check the meter’s software and version information, and erase the MeterView Pro software installation files from the meter. Press the Enter button to view the settings and the Menu button to exit at any time.

For a description of the diagnostic messages, see Advanced Features Menu & Display Messages, page

36.

Determining Software Version

To determine the software version of a meter:

1. Go to the Diagnostics menu (diAG) and press Enter button.

2. Press Up arrow button and scroll to Information menu (Info).

3. Press Enter to access the software number (SFT) and version (UER) information. Write down the

information as it is displayed. Continue pressing Enter until all the information is displayed.

4. The meter returns to Run Mode after displaying all the settings.

Reset Meter to Factory Defaults

When the parameters have been changed in a way that makes it difficult to determine what’s happening, it might be better to start the setup process from the factory defaults.

Instructions to load factory defaults:

1. Enter the Advanced Features menu. See Advanced Features Menu, page 36.

2. Press Up arrow to go to Diagnostics menu

3. Press and hold Right arrow for three seconds, press Enter when display flashes reset. Note: If Enter is not pressed within three seconds, the display returns to Run Mode.

4. The meter goes through an initialization sequence (similar as on power-up), and loads the factory default settings.
