The Analyst 3Q power analyser offers the full range of power quality measurements required for professional testing in accordance with EN50160.
The Analyst 3Q power analyser offers the full range of power quality measurements required for professional testing in accordance with EN50160.
The new analyser uses a central rotary selector to simplify complex measurements.
Clear, understandable measurement information is achieved with a bright colour display with a two level backlight.
The display offers a quick and easy-to-understand presentation of digital and graphical parameters; an oscilloscope view shows three phases of voltage and current waveforms simultaneously.
The Analyst 3Q offers 10 days of recording with 10min averages or up to 66 days of recording in its power quality overview mode.
It measures all the parameters required by the EN50160 standard, including voltage, frequency, voltage dips, harmonics, flicker and unbalance.
For fully fledged troubleshooting, the Analyst 3Q also measures current and power variables; the capability of correlating all these measurements can speed and simplify problem analysis.
In the PQ power quality measurement mode, the colour bargraphs show whether all measured parameters are within acceptable limits; if any parameter is outside the limit, another one of the measurement positions can be used to 'drill' into the problem.
The wide range of measurements available allows power quality problems to be quickly resolved.
The Analyst 3Q is supplied in a protective, rubber holster and with voltage measuring leads, a three phase or four phase LEM-Flex flexible current probe set (depending on model), voltage measuring leads, PC connecting lead, PQLogView software and a rugged carrying case.
The PQLogView software is a one-step download, analysis, exporting and reporting software package.
The process makes measurement and reporting a straightforward, intuitive operation.
The tabbed operation of the PQLogView software enables all available views of the captured data to be displayed and reported with a click of the mouse.
Additional current probes are available for low current measurements.
Safety features conforming to IEC1010 provide confidence when working in hazardous voltage areas, while conformance to EMC standards ensures high reliability through reduced susceptibility to electromagnetic influences.
