INTRODUCTION

1. INTRODUCTION

1.1. FEATURES & ABILITIES

The Voltech PM6000 is a powerful and versatile precision power analyzer. The

accuracy and bandwidth of the PM6000 allow definitive measurements of all power

quantities to be made on all electrical and electronic products. In applications ranging

from a power supply operating in standby mode, through high-frequency power

converters, to large power transformers, the PM6000 provides stable, reliable, and

accurate measurements every time.

VOLTECH PM6000 USER MANUAL ISSUE 20 PAGE 1

use this Voltech product. If you experience any difficulty during

installation or use of the Voltech PM6000, or are unsure of any of its

features or abilities, please do not hesitate to contact either your

local Voltech supplier or one of our Voltech main service centers.

INTRODUCTION

Versatile Technology

The PM6000 couples a fast PCI bus architecture with powerful digital signal processing

to provide 5 mega-samples per second (MSPS) - processed on all channels -

simultaneously and continuously. This ensures that accurate real-time measurements

can be made on products such as power supplies, motor drives and lighting ballasts.

Up to 40 MSPS are available for burst and transient measurement modes.

There is room for up to 6 wattmeter channels to be installed into a PM6000 with a

variety of shunts and current sensors, creating flexible test options.

Rugged Performance

Each measurement channel can measure up to 2000Vpk and can accept a range of

Voltech plug-in current shunts and other current transducers. The PM6000

automatically recognizes Voltech shunts when the instrument is powered up and reads

the shunt’s own calibration data to ensure optimum accuracy. In this way, only the

standard measurement channel is required for all applications.

An embedded PC running the Linux operating system is used to display, communicate

and control all the available measurements.

Easy to use

The display soft keys and rotary control are used to select and group measurements,

display multi-phase sum quantities, calculate efficiency and to display waveforms. The

menu items may also be selected using the front panel short-cut keys or remotely on a

PC.

In this way, the PM6000 can be set up to make complex measurements in seconds.

Front panel settings may be stored for future use.

For on the spot assistance, a comprehensive help system is built in to the analyzer.

Evolving capability

A program of software enhancement is further developing the power of the PM6000.

Regularly visit the Voltech website to keep up to date with developments

QUICK START

2.4. WIRING AND GROUPS

The analyzer uses the concept of groups of measurement channels for many of its

functions. By default each channel is assigned to its own group, so Channel 1 is Group

A, Channel 2 is Group B, and so on.

For multiphase measurements, a number of channels can be assigned to a group

allowing precise frequency and phase analysis of the multiphase signals. The

frequency of the first channel in the group is used as the fundamental frequency for all

channels in the group, and all phase measurements are relative to the phase reference

(Voltage by default) of the first channel in the group.

Channels are assigned to a group by selecting the required wiring configuration from

the [WIRING] menu or by remote commands. The appropriate number of adjacent

channels will be included in the group.

This should be done before connecting the test leads to avoid confusion when wiring

up to the PM6000

Channel 1

QUICK START

1. In the [WIRING] menu, choose how you wish to group measurements together,

if required

In this example, CH1 and CH2 have been grouped together to measure a 3-phase

input, and CH3 and CH4 have been grouped together to simultaneously measure a

3-phase output

2. Choose and set up current and voltage transducers, as required and described

below.

3. Then make the physical connections, taking care to observe health and safety

regulations.

Each measurement channel has inputs for both voltage and current. The inputs are

fully isolated from each other and from ground. The instrument chassis must be Earth

grounded at all times

VOLTECH PM6000 USER MANUAL ISSUE 20 PAGE 6

QUICK START

For a discussion of three-phase measurements, see Voltech application note 104-022

‘Three-Phase Measurements’.

The three-phase 7-wire configuration may be used to measure total power on

distribution systems with center-tapped three-phase transformers. The connection

method is similar to the three-phase 4-wire 3-wattmeter method above, with all VLO

terminals of the analyzer common and a VHI terminal taken to each of the 6 line wires

VOLTECH PM6000 USER MANUAL ISSUE 20 PAGE 7

QUICK START

2.4.1 Voltage and Current Input Overview

Voltage

Voltages of up to 2000V peak may be connected directly to the black and yellow 4mm

safety sockets at the bottom of the channel. A yellow and black lead set is provided

with each voltage channel. When connecting the leads, ensure that the end closes to

the ferrite bead is connected to the PM6000.

Current

The measurement channel accepts a voltage of up to 2.5Vpk that is proportional to the

current being measured. This input allows a very wide range of external current

transducers to be connected, from low mA current shunts to MA current transformers.

For each type of transducer, the PM6000 may be scaled to read the correct current.

See the [SCALING] menu.

Any combination of Voltech shunts or other transducers can be used simultaneously on

different channels of the PM6000

The choice of current transducer will depend on:

• The current being measured, including peaks and transients.

• The accuracy required.

• The bandwidth required: Unless the waveforms are purely sinusoidal, a bandwidth

in excess of the fundamental frequency will be required.

• Whether there is DC current present.

• Convenience of connection – E.g. using a clamp-on current transformer, with jaws

that open, for quick connection in a fixed wiring loom.

• The effect of the transducer on the circuit.

VOLTECH PM6000 USER MANUAL ISSUE 20 PAGE 8

QUICK START

2.4.2 To connect an external resistive shunt:

1. Use the plug supplied to make the connections to the measurements

channel connections

2. Use good quality shielded twisted pair cable to minimize pick-up

•Figure 3 External Resistive Shunt with Shielded Twisted Pair

3. For optimum rejection of common mode signals, the 0V guard terminal

must be used. Connect this to the shield of the twisted pair cable, if

VOLTECH PM6000 USER MANUAL ISSUE 20 PAGE 9

QUICK START

available. If there is no shield, connect this directly to the ELO terminal

4. Enter the value in mΩ of the external shunt into the PM6000. See the

[SCALING], [External Shunt mV/A] menu. E.G. For a 100mΩ shunt, enter

the value 100

QUICK START

1. Follow the manufacturer’s instructions for the safe use and installation of the

transducer.

2. Connect the voltage output to the EHI and ELO terminals of the PM6000 channel

as above.

3. Connect the 0V guard terminal to 0V on the transducer if one is available. If not,

connect the 0V guard to ELO along with the transducer. Use the 0V guard

terminal as the 0V return for those transducers that require one.

2.4.4 To connect a transducer with a current output only

To use a conventional current transformer like the Voltech CL series, use a Voltech 1A

shunt as described later, and use the [SCALING] [AMPS SCALING] function to enter

the ratio of the current transformer. Low level blanking may need to be turned off (see

section 3.2.11).

2.4.5 Voltech Shunts

For optimum performance, Voltech provides two resistive shunts which mount directly

onto the measurement channels. These shunts include a precision resistive element

designed with minimum inductance for maximum high frequency performance. The

Voltech shunts:

• Connect directly to a measurement channel without any extra wiring.

• Have a very low effect on the circuit.

• Excellent high frequency performance.

• Automatically recognized by the PM6000 during power on and scaled

appropriately.

• Calibration constants are stored within the shunt module and read automatically

by the PM6000 for optimum traceable accuracy.

• 4mm safety connectors for direct connection to the circuit or current transducers

with a current output (e.g. current transformers). . A yellow and black lead set

is provided with each shunt channel. When connecting the leads, ensure that

the end closes to the ferrite bead is connected to the shunt.

• Two models, 30Arms and 1Arms.

The current range will be displayed as a measurement item when this is selected.

3.2.3 Coupling

Default: AC+DC

In AC+DC mode, the PM6000 includes DC signals in its analysis.

Select 'AC' to measure AC signals only. This is useful when attempting to measure the

ac characteristics of a signal that are superimposed on a high level of dc. For example, to measure the ac ripple on a dc bus, select 'AC' only.

In either coupling mode, the analyzer will accept peak voltage or current up to its

normal rating. It is therefore safe and accurate to measure small amounts of ac ripple when connected to a 350V dc bus with ‘AC’ coupling selected.

3.2.4 Scaling

Scaling is used to adjust the scaled output of transducers such a current transformers

such that the true measured current is displayed on the PM6000

Maximum scale factor: 100 000

Minimum scale factor: 0.000 01

Amps Scaling

Default: 1

Enter the scale factor of the transducer being used. For example, the Voltech

CL1000 produces 1 amp for every 1000 amps flowing in the opening of the CL. It

is a 1000:1 current transformer. Enter the scale factor 1000 and the PM6000 will

display the correct current.

Scale factor = Transducer Input Current / Transducer Output Current

Volts Scaling

Default: 1

Enter the scale factor of the transducer. E.g. a 100:1 voltage transformer is used

to measure 15kV. The output of the transformer is 15000 / 100 = 150V. Enter the

scale factor 100, and the PM6000 will display 15,000 V

External Shunt Scaling mV/A

Default: 12.5 or value for detected Voltech Shunt

External shunt scaling is automatic when Voltech current shunts are used. Shunt

types are detected during power up of the analyzer.

This scaling is applied to the current measurement channel voltage inputs. This is

used for current transducers that have a voltage output. These include Hall-effect

transducers as well as simple resistive shunts.

Enter the scaling of the chosen transducer. For example a clamp-on Hall-effect

current transducer measures up to 100A. It has a voltage output of 10mV per

amp. Enter '10' and the PM6000 will display the correct system current.

VOLTECH PM6000 USER MANUAL ISSUE 21 PAGE 7

MENU SYSTEM

3.2.5 Filter

Default: 2MHz

This is the filter applied to all measurements for the group. It defines the measurement

bandwidth. Different filter settings may be applied to different groups.

The default setting of 2MHz is suitable for most general applications. The PM6000

always maintains a sample rate sufficient to avoid aliasing problems at any filter setting.

A range of filters is provided to allow the user to optimize the measurement

performance. The nominal filter frequency corresponds to the -3dB frequency so allow

sufficient bandwidth to include all harmonics of relevance to the measurements with

some margin.

As a guideline select a filter of ten times the highest frequency of interest.

Selecting a lower frequency filter will help reduce noise on some measurements or may

be useful to eliminate unwanted higher frequency components of low frequency

signals.

For settings of 2MHz and below, the signal is analyzed continuously; ensuring no

characteristic of the signal is missed.

The 10MHz filter puts the instrument into a 40MSPS burst mode, allowing analysis of

signal components up to 10MHz. This mode is only suitable for signals with a

fundamental frequency greater than 10 kHz.

Experiment with filter settings to find the most appropriate for each application

3.2.6 Frequency Source

Source

Default: Volts

Many measurements (including rms volts, amps and watts) are based on

calculations that are dependant on the correct fundamental frequency being

determined by the analyzer.

The PM6000 uses proprietary techniques to determine frequency that eliminate

the problems created by noise when simple zero-crossing techniques are used.

It is therefore not normally necessary to adjust the settings from the default of

VOLTECH PM6000 USER MANUAL ISSUE 20 PAGE 8

MENU SYSTEM

Volts is the default frequency source and is suitable for most applications.

Amps may be selected if the voltage waveform is heavily distorted, but the

current is not. The waveforms at the output of a PWM motor drive are an example

of this.

External sets the external input at the back of the PM6000 as the frequency

source. Choose this option if the frequency cannot be detected from volts or

amps but is available elsewhere. Apply a TTL compatible square wave to the

external input at the required frequency.

Fixed Frequency Enter a frequency and this will be used as the fundamental

frequency for measurements.

Phase Reference

Default: Volts

This is the zero reference for phase angle measurements in each group.

Volts Phase is calculated with respect to the voltage signal on the first channel in

the group

Amps Phase is calculated with respect to the current signal on the first channel in

the group

Low Frequency

Default: OFF

Tick this option if the fundamental frequency is expected to be below 5Hz.

Enter sub menu to specify the frequency

1 - 5Hz - The analyzer will update once per second and a half

< 1Hz - The analyzer will update once every 16 seconds, allowing

measurements down to 0.1Hz.

MENU SYSTEM

3.2.7 Mode

Default: Normal

This menu contains the special application modes of the PM6000. When selected, the

analyzer will be automatically set to use the optimum measurement techniques for the

waveforms under test

Normal

This is the default operating mode of the analyzer and is ideal for making

measurements in most applications. The frequency will be continuously detected

(unless fixed) and the graph timebase will be set to show two cycles of the

fundamental frequency of the first displayed channel

PWM Output

This mode should be used to analyze the output of electronic motor drives.

The output waveform of a PWM drive is a complex mixture of high and low

frequency components that can be difficult to accurately assess. In this mode, the

data is sampled at high speed but aligned with and over an integral number of

cycles of the low frequency motor frequency. The modulation (or motor)

frequency is specifically detected every few seconds from the voltage signal.

When performing harmonic analysis of PWM motor signals there are several

factors that affect the measurement update rate. The harmonic analysis time

increases as the motor frequency decreases. Since the PM6000 will complete the

analysis of all requested harmonics before measuring the motor frequency,

increasing the maximum harmonic number will make the motor frequency

detection less frequent. As such, if the motor frequency is fluctuating significantly

or if close tracking of the motor frequency is required, then reduce the maximum

harmonic number or turn harmonic results off.

The graph display will attempt to display the modulated waveform for both voltage

and current at the motor frequency

See the Voltech Technical Note 86-165 for a more detailed discussion of the

application

VOLTECH PM6000 USER MANUAL ISSUE 20 PAGE 10

MENU SYSTEM

Minimum Fundamental Frequency

Default: 5Hz

Set this to allow for the lowest expected fundamental frequency. The

instrument will increase the analysis time so that the lowest frequency can

be detected. The results update rate will be correspondingly affected.

0.1 Hz

1 Hz

5Hz

HF Ballast (AM)

This mode is ideal for making accurate measurements on AM (amplitude

modulated) power signals or signals with fluctuating or unstable frequencies.

These waveforms are found at the output of electronic lighting ballasts, ultrasonic

supplies for cleaning, medical imaging and radio frequency cutting equipment.

The PM6000 sets the sample time to be an integral number of cycles of the

modulation frequency to ensure accurate results.

This frequency can be determined in a number of ways allowing the user

significant flexibility

To minimize the effect of modulation on the results, a Harmonic Scaling

technique is used. This uses the harmonic analysis to compensate for the effect

of the modulation on the harmonic parameters

For more information, see Voltech Application Note 101, part number 98-030

VOLTECH PM6000 USER MANUAL ISSUE 21 PAGE 11

MENU SYSTEM

Freq source

Default: 50/60Hz

This setup parameter allows the user to control how the instrument

determines the modulation frequency. This is important for AM signals as

the PM6000 will adjust the analysis period to an integer number of complete

cycles to ensure accurate results

From Channel

The modulation frequency can be taken from the detected frequency

of another channel. This channel must be in Normal mode. Available

channels are shown in the selection menu. If the selected channel is

unable to detect a valid frequency then the Ballast mode results will

show invalid results

50/60Hz

When selected the analysis period is set to 300ms ensuring an

integer number of cycles for both 50Hz and 60Hz modulation

Fixed Frequency

If known, the modulation frequency can be entered directly

Harmonic Scaling

Default: ON

This provides a correction for the variation of the signal harmonics due to

the modulation frequency. This only affects harmonic and THD results

The accuracy of the harmonic results improves with increasing number of

harmonics enabled.

It is recommended to set the maximum harmonic number to at least 20

3.2.8 Integrator

Default: OFF

The integrator is used to determine the characteristics of an electrical system over time.

For example, a washing machine consumes different amounts of power at different

times. The energy rating over an operating cycle can be determined using the

integrator.

The PM6000 provides a highly flexible integration system that allows multiple

integrations to be configured and run independently.

Enabling the integrator will display rows for the integration parameters and show results

for each channel in the integrated group

Using the remote commands the PM6000 can be used to perform high speed, complex

or repetitive measurements. Many of the PM3000 commands are supported although

the increased flexibility of the 6-channel PM6000 design brings the new concept of

multiple groups of channels.

Many of the functions apply to the currently selected group of channels. By default,

each measurement card is grouped individually. Read the section on Wiring for further

discussion on groups.

4.2. INTERFACING WITH GPIB SYSTEMS

The PM6000 remote commands are compatible with IEEE488.2. However a hardware

GPIB interface is not provided. Commercially available GPIB to RS232 converters can

be used to provide connection to GPIB control systems. One example is the National

Instruments GPIB-232CV-A that has been reliably used with the PM6000 at 38400

baud. Refer to the National Instruments documentation for more details.

4.3. INTERFACING WITH RS232 SYSTEMS

The RS232 port is a standard PC type 9 way male D-type located on the rear of the

instrument and may be used for remote control of the PM6000. A null modem cable

should be used.

The RS232 port uses 8 bit, no parity, one stop bit and hardware flow control.

See section 8.4.1 for a detailed pin description of the RS232 connector.

See section 3.2.14 for details on the interface menus.

NOTE: To avoid any communications problems, a delay of 250mS should be included between each command sent to the PM6000.

4.4. INTERFACING WITH ETHERNET SYSTEMS

You can remote control your PM6000 through Ethernet port by using the Microsoft

Telnet Client.

• On Windows XP, click Start > Run and type telnet xxx.xxx.xxx.xxx where

VOLTECH PM6000 USER MANUAL ISSUE 21 PAGE 1

MENU SYSTEM

• xxx.xxx.xxx.xxx is the IP address of the PM6000. (see section 3.2.14 on how to

obtain the Ethernet IP address).

• At the login: prompt type:

pm6coms

• You should see a response from the instrument, such as:

Welcome to Voltech PM6000 Power Analyzer

PM6000>

• Enter commands for the PM6000 after the 'PM6000>' prompt.

• To finish the remote control by enter command:

Exit

Note: During Ethernet connectivity all write commands have a return string sent back containing a space. Therefore during programming a receive buffer flush is required

after every write command.

4.5. REMOTE COMMAND SYNTAX AND CONVENTIONS

The following conventions are used for command syntax

• Square brackets indicate optional parameters or keywords [ ]

• Triangle brackets indicate values to be specified < >

• Vertical bar indicates the choice of parameters |

Commands and responses are sent as ASCII strings terminated with a carriage return

(ASCII 13). The PM6000 is not case sensitive and white space characters are ignored

except where required between command and parameter.

Multiple commands can be sent in a single string where a ‘;’ character is used at the

end of each command.

The PM6000 will respond to invalid commands by adding an error message to the error

queue. It is recommended that the error queue is checked after issuing command

sequences by using the SYST:ERROR queries to ensure successful configuration

PM6000 will always replys at least one char to the clinet socket.

During Ethernet connectivity all write commands have a return string sent. If the

command that the client socket sent to the PM6000 was a asking command (e.g.

VOLTECH PM6000 USER MANUAL ISSUE 20 PAGE 2

MENU SYSTEM

:BRF?), then the return string is the results were asked. If the command is a configure

command (e.g. :SEL:VLT) that no result was asked, PM6000 will send a " " (a space)

as the reply. Thus in your program, writing a configure command must followed by a

read (i.e. during programming a receive buffer flush is required after every write

command), otherwise all the " " chars will prefixed the next real result, that will cause

error in the results process methods.

4.6. STATUS REPORTING

The PM3000 had four status bytes used to determine the overall status of the

instrument. These have also been included in the PM6000, although the background

status register and display data status register are effectively the same because in the

PM6000 there are not separate averaging buffers for both remote commands and the

display.

4.6.1 Status Byte Register

This register is read using the “*STB?” command. A value is returned representing a bit

pattern. Each bit represents a condition

Bit Condition Description 0 DAS Summary bit for data status 1 BAS Summary bit for data status. This condition is exactly the

same as DAS on the PM6000, but is preserved for

backwards compatibility

2 3 4 MAV Always 0 for RS232 5 ESB Summary bit for data status 6 MSS Master summary status, set if any of the other bytes in the

service request enable register is also set

VOLTECH PM6000 USER MANUAL ISSUE 21 PAGE 3

MENU SYSTEM

4.6.2 Background and Display Status Register

In the PM3000 these were separate status registers. In the PM6000 the same register

is used. Both the “:BSR?” and “:DSR?” commands read from this register.

Bit Condition Description 0 DVL Set when data is available 1 NDV Set when data is available 2 AVF Set to when the averaging buffer is full to the specified

depth

3 OVV Set when a voltage over range has occurred 4 OVA Set when a current over range has occurred 5 6 7

4.6.3 Standard Event Status Register

This register is read using the “ESR?” command.

Bit Condition Description 0 OPC Set after a *OPC command has been received, once all

messages sent have been processed

1 2 QRE Un-terminated query error 3 4 EXE Execution error. A command parameter was invalid or out

of range

5 CME Command error. The command was not recognized 6 7

Description: Sets up the averaging buffer for the measurements made

by the PM6000. The sample period is approximately a third

of a second so for an averaging buffer depth of 16, the

buffer will fill in around five seconds. When in ‘auto’ mode,

the buffer will be cleared if a significant change in value is

detected. This has the effect of minimizing the drift

between values. It will however affect the use of the

Average Buffer Full status bit, as this will only be set when

the buffer has valid values to its full depth. If this status bit

is being polled, it is recommended to use fixed averaging

mode.
