JOULEWATT.jpg (144649 字节) 

The Joule/Watt Meter measures the cumulative electrical energy delivered to a load from a power supply as well as instantaneous power. This instrument is designed for the direct measurement of the electrical energy or instantaneous power supplied to a load. It eliminates the need to calculate results obtained from readings gained using a voltmeter, ammeter and stopwatch.

The instrument takes low experimental input of 24VDC or 18VAC max. To enable measurements of heat or energy in electrical circuits as well as LCR circuits.

Output can be measured using the pulsed out put on a external counter or a data-logger.

Output voltage: 3.3V

Similarly the power can be measured between 0-1V on the terminals for data-logging.
