The JS220 is the second generation Joulescope instrument. It measures current, voltage, power, energy, and charge. Like the first generation JS110, the JS220 contains an autoranging shunt ammeter that supports an amazing dynamic range, a perfect match for characterizing and optimizing modern electronics. The JS220 offers significantly higher performance with even more features than the JS110.
