Introduction The following paragraphs outline some of the differences between this version of PAS in comparison to previous versions you may have used. Installation If you install the new PAS into the same directory where your current version of PAS is installed, it is recommended that you do not uninstall your old PAS before installing this version; otherwise, your present PAS configuration database will be destroyed.
1 Chapter Communicating with Your Meters Creating a New Site In order to communicate with your meters, you should create a separate site database for each one where all meter settings are stored. PAS keeps all site settings in a file with a name you give it and the extension .mdb. When you install PAS on your computer, a directory named "Sites" is created in the PAS installation directory. It is advised to keep all your site databases in this directory.
C O M M U N I C A T I N G W I T H Y O U R M E T E R S options for your meter. If the meter has an onboard logging memory, select the correct memory module size for your meter. You can add any comments to the 'Comments' box, such as meter location or any other data concerning this particular site. You cannot change the site properties or communication settings when the 'On-line' button on the toolbar is checked. Uncheck it before entering the 'Configuration' dialogs.
C O M M U N I C A T I N G W I T H Y O U R M E T E R S The remaining settings in this dialog do not normally need to be changed. The 'Response Time-out' box defines the maximum time in milliseconds that PAS will wait for the meter response before announcing a failure. When communicating through a modem, especially over long distances, this time may require some adjustment.
C O M M U N I C A T I N G W I T H Y O U R M E T E R S Communicating through a Modem On the 'Connection' tab, select in the 'Device' box a local modem installed on your PC through which you will communicate to your meter. Click on 'Phones' to add the phone number of the remote modem to the phone list. Type the phone number in the 'Phone number' box, add comments if you desire, click 'Add', and then click 'OK'. In the 'Phone number' box on the 'Connection' pane, select the phone number from the list.
2 Chapter Programming Your Meters Creating Setups for Your Meters Off-Line PAS allows you to prepare setup data for your meters off-line without the need to have the meter connected to your PC. You can save these data in the meter's site database, and then recall and download it to the meter when you have the meter on-line. T o prepare a setup for your meter, select a meter site from the list box on the toolbar, and then select the desired setup group from the 'Meter Setup' menu.
P R O G R A M M I N G Y O U R M E T E R S PAS uses the Basic Setup data as a reference in all setup dialogs. Create the Basic Setup configuration for your meter first and save it to the site database before preparing other meter setups. Note If you want to reuse setups from another site, you can simply copy setups from that site to your present site database. Click 'Open', select the desired site database, and then click 'OK'. The opened setup will be copied to your site database.
3 Chapter Monitoring Your Meters Viewing Real-time Data Real-time data can be continuously retrieved from your meters and updated on the screen at a rate you defined in the Instrument Setup. T o poll your instrument, select a meter site from the list box on the toolbar, select 'RT Data Monitor' from the 'Monitor' menu, and then select a data set you want to view. PAS supports 33 programmable data sets each consisting of up to 40 data parameters.
M O N I T O R I N G Y O U R M E T E R S To run data polling, check the 'On-line' button on the toolbar, and then click on either the 'Single poll' button or 'Continuous poll' button . When in continuous poll, you can stop it by clicking on the 'Stop' button . You can open as many data monitor windows as you want, either for different sites, or for the same site using different data sets. When you open a data monitor window, it is linked both to the current site and to the selected data set.
M O N I T O R I N G Y O U R M E T E R S Select a directory where you want your log files to be kept. To avoid confusion, do not store data files into the 'Sites' directory where site databases are located. Select an existing file or type the name for a new file, and then click 'Save'. Printing Data to a Printer To print retrieved data to a printer, click the print button on the toolbar, select a printer and click 'OK'.
M O N I T O R I N G Y O U R M E T E R S suspend logging by un-checking this button, and then resume logging by checking it again. Viewing Real-time Min/Max Log T o retrieve the real-time Min/Max log data from the meter, select a meter site from the list box on the toolbar, select 'RT Min/Max Log' from the 'Monitor' menu, and then select a data set you want to view. PAS supports nine programmable data sets each consisting of up to 40 data parameters.
M O N I T O R I N G Y O U R M E T E R S Updating the Clock in Your Meters T o update clock (RTC) in the meter, select a meter site from the list box on the toolbar, check the 'On-line' button on the toolbar, and then select 'RTC ' from the 'Monitor' menu. The RTC dialog displays the current PC time and the time in the meter. To synchronize the meter clock with the PC time, click 'Set'.
4 Chapter Retrieving Historical Data from Your Meters If your meter has on-board logging capabilities, you can retrieve the historical logs from the meter and save them to the database for later analysis. This can be done in two ways. The first is uploading historical data on demand at any time you need them. The second is using the upload scheduler that runs at predefined intervals on your schedule, for example, daily, weekly or monthly. Historical logs are stored as separate tables to the .
R E T R I E V I N G H I S T O R I C A L D A T A Adding a New Site to the Schedule Click 'Add Site', select the site database for which you want to organize the schedule, and then click 'OK'. Configuring a Schedule for the Meter Click 'Configure' or double click with the left mouse button on the site row. Click on the 'Select logs' button, check boxes for logs you want to upload on a schedule from the meter, and then click 'OK'. Pay attention to the Note in the previous section.
R E T R I E V I N G H I S T O R I C A L D A T A To keep the Upload Scheduler running, the 'On-line' button on the toolbar must be checked all the time. If you uncheck it, the scheduler will stop operations. This will not cause loss of data, since the scheduler will resume operations when you check this button again. Keeping it running Suspending the Scheduler To suspend the Upload Scheduler, check the 'Suspend Scheduler' box at right. To activate the Upload Scheduler, leave this box unchecked.
5 Chapter Viewing Log Files Data stored into data files can be viewed on the screen in different formats. You can see how they look on your screen and check different options by opening sample files you received with PAS. They are located on your disk in the 'Samples' directory under the PAS installation directory. Opening a Log File T o open a log file, click on the 'Open' button at left of the toolbar, or select 'Open...' from the 'File' menu.
V I E W I N G L O G F I L E S Select an existing file or type the name for a new file, and then click 'Save'. Printing Data to a Printer To print data to a printer, click the print button on the toolbar, select a printer and click 'OK'. If you want to check how your document appears on the printed page, select 'Print Preview' from the 'File' menu. Viewing the Event Log E vent log files are displayed in a tabular view, one event per row.
V I E W I N G L O G F I L E S Viewing the Data Log D ata log files are displayed in a tabular view, one data record per row. PAS loads the entire data log file (or database table) to a window. There are no any specific controls available for data log views. Viewing the Waveform Log W aveform log data can be displayed in five different views. When you open a new file, PAS shows you a waveform graph with overlapped waveforms.
V I E W I N G L O G F I L E S If you do not want to view all waveforms together on one screen, you can use filtering to work with a subset of waveforms that meet your criteria. PAS will temporary hide waveforms you do not want displayed. To select desired waveform channels, click with the right mouse button on the waveform window, select 'Options...', check the channels you want displayed on the 'Channels' tab, and then click 'OK'.
V I E W I N G L O G F I L E S Viewing Phasor Diagrams Waveform views have an additional pane at the lower right, where PAS draws phasor diagrams for displayed waveforms. The phasor diagrams show you the relative magnitude and angle of the fundamental harmonic for the selected voltage and current channels. All angles are taken relative to the reference voltage channel. To change the reference channel, click with the right mouse button on the waveform window, select 'Options...
V I E W I N G L O G F I L E S Using the Marker Lines Waveform and RMS panes have two blue dashed marker lines. The left marker indicates the position from where data will be taken to calculate the harmonics spectrum and phasor diagrams, and also the starting position for calculating the RMS, average and peak values. The right marker indicates the end position for calculating the RMS, average and peak values. The minimum distance between the two markers is exactly one cycle.
V I E W I N G L O G F I L E S local toolbar; to select a non-overlapped view, click on the button two waveforms. showing Waveform data are recorded to files in series that may contain many cycles of the sampled waveforms. A waveform window can display up to 64 waveform cycles. If the waveform contains more than 64 cycles, the scroll bar appears under the waveform pane allowing you to scroll through the entire waveform.
V I E W I N G L O G F I L E S Viewing a Spectrum Chart To view the spectrum chart for the selected waveform channel, click on the button representing a spectrum graph. The spectrum is calculated over four cycles of the selected waveform beginning from the point where the left marker line is located in the open waveform view. If both waveform views are open, PAS gives the priority to the overlapped waveform view.
V I E W I N G L O G F I L E S Viewing a Spectrum Table To view the harmonics spectrum in a table view, click on the button on the local toolbar. PAS allows you to view either a spectrum table for the selected channel, or all channels (V1-V3 and I1-I3) in a single table. Refer to section 'Selecting Waveform Channels' above for instructions on how to select waveform channels.
6 Chapter Customizing Your Views Customizing Date Format T o change the way PAS displays the date, select 'Customize' from the 'Tools' menu, click on the 'Preferences' tab, select the preferred date order, and then click 'OK'. Customizing Timestamp T he timestamp is normally recorded in the data log files and displayed on the screen at a 1-ms resolution. If you have an application that does not support this format, you can instruct PAS to drop the milliseconds.
