1. cccccccsssseseeeeeeeees 5 3 ANSWERS TO THE MOST COMMONLY ASKED QUESTIONS 6 1 il SETTING UP AND USING THE ELITEpro and DATApro LOGGERS Introduction The ELITEpro and DATApro instruments are interval data recorders that can be used to measure and record a wide variety of physical parameters volts watts temperature 4 20 mA and more Despite their small size and relatively low cost these instruments are very sophisticated accurate and versatile The measurements are stored in on board memory in a time series format or time bins at an interval selected by the user The time bins can be as short as every 3 seconds or as long as every 24 hours Regardless of the storage interval selected the logger is sampling its sensors every three seconds when on external power from the included wall transformer or every minute when using its internal battery These readings are then used to determine the average or maximum or minimum value that is stored in each time bin The Loggers require a computer PC and special software ELOG for initial setup and later data retrieval and analysis To use the ELOG software it must first be installed on your computer Do this by putting the CD into the appropriate drive or Disk 1 if using floppies The CD is auto loading so simply follow the directions on the screen When the ELOG software Is run the MAIN MENU will appear which consists of one line of standard Windows menus structur

15. there are two times when it may be desirable to use the 3 watt element method They are 1 The 3element method is more intuitive By placing a CT on each phase wire it is easier to understand what is happening in each phase without referring to phasor diagrams 2 Different power factor calculation As noted in the description of the Power Sum Equations above the System VA and consequently System Power Factor are calculated differently between the 2 and 3 element methods In 2 element measurements Systems VA is calculated from Watts and VARs using the power triangle In 3 element measurements System VA is calculated as the sum of the VAs from the individual phases Both methods are completely valid The major difference is how harmonics are treated When harmonics exist they are usually only or mostly present in the current and not in the voltage Because watts and VARs are calculated as the instantaneous product of volts and amps and because an existing third or fifth harmonic current does not have a corresponding voltage harmonic then the harmonics products are zero Therefore the instantaneous product of volts and amps used to obtain watts and VARs does not include any harmonic component Thus the 2element method does not include any harmonic content in the calculation of System VA or System Power Factor The Power Factor calculated in this way is also known as the Displacement Power Factor 5 1 In 3 element systems b

Serial Adapters A growing number of laptop computers and other devices no longer have serial ports on them Instead the serial ports have been replaced by USB Universal Serial Bus ports USB ports may be connected to ELITEpros and DATApros by using a suitable USB to Serial adapter These may be found from a number of sources including office equipment stores such as Office Max and Staples To use simply connect the adapter between the logger and the PC and connect to the logger as you normally would We have noticed that sometimes the adapters drop or repeat characters between the logger and PC causing a communication failure This can be minimized by using a lower baud rate In general use the highest baud rate that gives a reliable connection For a direct serial connection that is almost always the maximum rate of 57 600 baud With the USB adapter it may need to go to 28 800 or even 9 600 baud to get reliable communication A description of changing the baud rate is found in Section 2 Tools PC Setup ELOG 2002b October 20 2002 or higher is required to use the USB adapters Consult DENT Instruments if you have any problems 2 USING THE 3 WATT ELEMENT 3 CT METHOD ON A 3 WIRE DELTA SERVICE Using the two watt element method on 3 phase 3 wire Delta services is a perfectly valid measurement technique The 2element method also uses less logger memory and hardware channels and allows measuring two Delta 3 wire loads simultaneously However
