PX and PX TRMS three and single phase digital wattmeters For measurements onsite or - PDF document

For measurements on-site or in a laboratory, ¥¥¥¥¥ DC or AC TRMS networks: balanced single-phase (PX 110) or three-phase (PX 120) Â¥ ltage, current, active/reactive/apparent powers and power factor measurements Â¥ High degree of sensitivity Â¥ Simple and quick implementation with direct access keys Â¥ Numerous automatic functions: current range switching, HOLD, filtering, starting current, etc. Â¥ Excellent readability: 3 quantities displayed simultaneously with Â¥ Digital transmissions protected by infrared communication interface Â¥ Mains power supply (optional) ottering contacts are a thing ofperformed merely by a mag- sensitivity, the PX 120 and PX 110 arevocational training; examples of which areinstallers and comdepartments. To be more precise, theirability to measure RMS values in AC + DCmeasurements in the 4 quadrants on sig-nals which are disturbed and polluted bytalking about a new breed of instrument:The only difference between the two mod-els is that the PX 120 measures powersusing the three-phase three balanced wiresystem, whereas the PX 110 is reserved for Smoothing function The SMOOTH function is very useful fromthe moment the measurement in questionmeasurements with a time constant ofapproximately 3 seconds. Display stabilitythen goes from 5 counts to 2 counts. Exceptional readability In addition to a particularly large digit size(14 mm), the readout unit of the PX 1209,999 counts (4 digits) on three lines. Theuser thus simultaneously displays threevalues. Two different tables then suffice todisplay all the quantities measured by thedifferent symbols which, at any moment,battery. Protected digitallink and software The PX 120 and 110 have an infrared digitalnection into place. Moreover, this trans-improved safety; besides, the PX 120 and110 comply with the IEC 61010-1 standardA processing software package thenenables different quantities to bedisplayed on the screen of a PC, screenmeasurement files to be transferred to aspreadsheet and stored. User comfort and sturdiness Their casing reinforced with an elastomerhandholding capability and a sturdinessstand allows the instrument to be proppedto read the results. This stand is retractedwhen measurements are carried out on site. Easy implementation Although they offer elaborate functions, thePX 120 and PX 110 are very simple to(PX 120) keys corresponds to a singlethen accessible via a single press of thekey. Finally, the automatic change of rangebe powered by batteries or the mainspower supply. Starting current There are loads, such as engines, someheating resistors or lighting systems which,rush of current. Although they last only ashort time, these currents can triggerinstallation. To counter this, the PX 120and PX 110 are provided with the INRUSHmeasured).
