If a product uses power, then power consumption and power quality measurements must be made as part of product design and test. These measurements are essential to optimize product design, comply with ...

Measurement of average power in a 60Hz circuit (equivalent to V RMS × I RMS × cos(ø)) can be done by sampling the product of voltage and current and averaging. This requires four quadrant ...

You almost never hear of a DC Watt Meter – one just does some mental math with Volts and Amps at the back of one’s head. An AC Watt Meter, on the other hand, can by pretty useful on any workbench.

The demand to increase energy efficiency in electrical products is driving the development of more accurate measurement instruments. Modern instruments now can quantify incremental gains made as ...

Focusing on power calibration to deliver quality results at a reasonable cost Yokogawa Meters & Instruments Corporation announces that it has developed the LS3300, an AC power calibrator that can ...

If you want to measure voltage you reach for a voltmeter. Current? An ammeter. Resistance? An ohmmeter. But what about measuring AC power? A watt meter? Usually. But if you know what to do, you could ...

Intended for reliable and comprehensive calibration of power meters, the LS3300 Precision AC Power Calibrator outputs highly accurate and stable power calibration signal, which now include harmonics, ...

A novel sensor enables them to do just that, and thereby comply with the new government regulations. The new metering device will be presented at the Sensor+Test 2012 trade fair in Nuremberg from 22 ...

A new DC input power supply option is available for the vendor’s DL750 ScopeCorder, a modular measurement tool that can capture up to 16 analog inputs as fast as 10 MS/s plus 16 logic inputs ...
