PX 120 and PX 110 TRMS three- and single phase digital wattmeters For measurements on-site or in a laboratory, a new concept: the digital power meter! * DC or AC TRMS networks: balanced single-phase (PX 110) or three-phase (PX 120) * Voltage, current, active/reactive/apparent powers and power factor measurements * High degree of sensitivity * Simple and quick implementation with direct access keys * Numerous automatic functions: current range switching, HOLD, filtering, starting current, etc. * Excellent readability: 3 quantities displayed simultaneously with a digit height of 14 mm * Digital transmissions protected by infrared communication interface * Mains power supply (optional) PX 120 and PX 110: TRMS three- and single phase digital wattmeters More than a wattmeter, a power meter! Given their wide measuring range and their sensitivity, the PX 120 and PX 110 are intended for both general teaching and vocational training; examples of which are installers and company maintenance departments. To be more precise, their ability to measure RMS values in AC + DC (or TRMS) enables them to carry out measurements in the 4 quadrants on signals which are disturbed and polluted by harmonics. For these applications the PX 120 and 110 go well beyond the functions generally available on traditional wattmeters. That is why we should be talking about a new breed of instrument: the power meter! The only difference between the two models is that the PX 120 measures powers using the three-phase three balanced wire system, whereas the PX 110 is reserved for single-phase networks. Easy implementation Starting current Smoothing function Exceptional readability Although they offer elaborate functions, the PX 120 and PX 110 are very simple to implement. Each of the five (PX 110) or six (PX 120) keys corresponds to a single clearly identifiable function. The latter is then accessible via a single press of the key. Finally, the automatic change of range means that the user avoids having to carry out any adjustments. The instrument can be powered by batteries or the mains power supply. There are loads, such as engines, some heating resistors or lighting systems which, when started up, cause a considerable rush of current. Although they last only a short time, these currents can trigger the safety devices or even damage an installation. To counter this, the PX 120 and PX 110 are provided with the INRUSH function, which consists in measuring the maximum value of the samples over a halfperiod (with this value being maintained until a new and higher value is measured). The SMOOTH function is very useful from the moment the measurement in question is an unstable one. It filters the measurements with a time constant of approximately 3 seconds. Display stability then goes from 5 counts to 2 counts. In addition to a particularly large digit size (14 mm), the readout unit of the PX 120 and PX 110 has a display capacity of 9,999 counts (4 digits) on three lines. The user thus simultaneously displays three values. Two different tables then suffice to display all the quantities measured by the instruments. This digital display is supplemented by different symbols which, at any moment, indicate the operating mode used, the units of each quantity or the state of the battery. User comfort and sturdiness Their casing reinforced with an elastomer mould gives these instruments an excellent handholding capability and a sturdiness which is second to none. In the event of it being used on a table, a stand allows the instrument to be propped up at an angle of 30, thus making it easier to read the results. This stand is retracted into its housing on the back of the casing when measurements are carried out on site. Protected digital link and software The PX 120 and 110 have an infrared digital link, thus making it easier to put the connection into place. Moreover, this transmission mode guarantees the user improved safety; besides, the PX 120 and 110 comply with the IEC 61010-1 standard (Category III - 600 V - Pollution level 2). A processing software package then enables different quantities to be displayed on the screen of a PC, screen print-outs to be obtained, and even measurement files to be transferred to a spreadsheet and stored. Display kept visible Smoothing mode Units Communication mode Starting current mode Balanced three-phase Power factor Owing to their stand, the PX 120 and PX 110 are as much at ease on a table as in your hand. Tottering contacts are a thing of the past, the connection is now performed merely by a magnetised optical head which is simply placed on the front panel of the instrument. Battery rundown With the 73 x 54.3 mm LCD display, the user knows what the situation is at a glance. The battery rundown indicator light warns him when the period of autonomy is down to one hour.
