2.2. AVIGATING THE YSTEM The menu system provides complete access to all settings of the PM6000. The menu system may be accessed as follows: 1. By use of the 6 soft keys found to the right of the display 2. By using the short-cut keys on the front panel. These keys are grouped in a logical left to right sequence for setting up the instrument and provide fast access to the top-level menu items.

Page 22 Having an appropriate choice of voltage and current transducers and a careful wiring arrangement, the PM6000 can now be set up via its menu system to make a wide variety of power related measurements. For a description of each of the menu options, see the next section.
Page 23: Menu System
3.1. AVIGATION The PM6000’s menu is a powerful yet easy-to-use system for control of the analyzer. See the ‘Quick Start’ section of this manual for an overview of how to access and use the menu system. The soft-key actions are repeated here for convenience.

Page 27 200V then signals with a peak of ± 200V can be measured. Voltech Shunts will be scaled on instrument power up. For other shunts the relevant scaling should be applied using the External Shunt Scaling menu (see 3.2.4)
Page 28 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.
Page 29 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.
Page 30 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.
Page 31 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.
Page 32 YSTEM 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.
Page 33 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.
Page 34 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...

Page 70: Remote Command Syntax And Conventions
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.

Ethernet is required for firmware upgrades (section 9.4) and for access results via FTP (section 5.2). 5.1.1 Network Connection Method This would be the method that you would use if you were to attach your PM6000 to a local area network. The PM6000 supports networks with and without DHCP (Dynamic Host Configuration Protocol).

Security Center icon on the Control Panel. From there, select Windows Firewall and then select Off. You should now have an Ethernet link between your PC and the PM6000. This can be tested by typing ‘ping’ followed by the PM6000 IP address (e.g. ‘ping 169.254.110.254’) at a DOS prompt.
Page 116 CCESS 5.2.1 Anonymous or User login The PM6000 allows both Anonymous and user logins. The differences are that in anonymous mode files can only be copied from the PM6000. If a user login is provided, files and directories can be copied, deleted and created, allowing better management of the PM6000 storage media.
Page 117 Files can now be copied from the PM6000 to your PC. In the case of FileZilla, this can be done by dragging the desired file from the PM6000 window in to the desired directory on your PC as listed in the windows on the left.
Page 118 EMOTE CCESS 5.2.4 Finding your way around The PM6000 allows FTP to all available storage media on the instrument. As such, once connected, the files and directories of interest need to be found. The file system is organized as follows /pub/floppy/ (if fitted) Contains files on the floppy disk in the instrument.
Page 119 Only files and directories in or below these directories will be visible and accessible from the instrument. WARNING: Various other files and directories may be visible by the FTP browser. Do not attempt to modify or delete these files as this may damage the instrument. PM6000 U OLTECH ANUAL SSUE...

3. Switch on the PM6000 and the new shunt will be automatically recognized by the PM6000. This can be confirmed in the [CONFIG] menu. If the shunt is not available, or any warnings are displayed during switch on, please contact you Voltech service center.

PM6000 easily meets the requirements of the latest version of EN61000-4-7 (harmonic measurement instrumentation) including the requirements for inter-harmonic grouping and a 200ms measuring window. The PM6000 also implements the requirements for a reference instrument by using a discrete Fourier transform as opposed to a fast Fourier transform (FFT), providing reliable, error-free harmonic measurements in all conditions.
Page 123 NOTE: When using the USB-6009 box from National Instruments, it is essential to ensure that the voltages applied to the USB-6009 do not exceed the rate voltage, which is nominally +/- 20V. Exceeding thr rate voltage could well result in permenant damage to the USB-6009. PM6000 U OLTECH ANUAL SSUE...

When comparing the current readings of a PM6000 without a shunt to the signals derived from an external source such as a calibration amplifier, to is essential to ensure that the calibration amplifier is loaded correctly as specified in it's user manual. For example, on a Fluke 6100A, a 10 Ohm resistive load would work.

This utility will provide all the instruction you need to finish the upgrade of the firmware for the PM6000. If your PM600 has version 1.06.01 firmware or earlier and/or you do not have a DHCP Ethernet connection, then you will need a keyboard connected to the PM6000.
Page 143: Safety Information
AFETY EATURES The PM6000 has been designed with safety features, such as shrouded safety connectors, that provide the operator with a high level of protection against the risk of electric shock. As with any dangerous equipment, however, it is important that an assessment of the overall risk to safety is made during installation.
