Measuring energy consumption during product development is crucial, especially for battery powered and always-on devices. However solutions to measure energy consumption accurately are normally expensive, tricky to use and also error prone. To solve this issue the team at Jetperch have created the Joulescope imprecision DC energy analyser. Watch the demonstration video below to learn more about the Joulescope and its features, which display waveforms of voltage, current, and power over time, like an oscilloscope.
Joulescope accurately measures electrical current over 9 orders of magnitude from amps down to nanoamps. This wide range allows accurate and precise current measurement for modern devices. Sleep modes are often just nanoamps (nA) or microamps (µA). Active modes are often milliamps (mA) or amps (A).
Features of the Joulescope include :
– Low voltage drop: Most multimeters and current meters have a significant voltage drop (sometimes called burden voltage or insertion loss) which effects the actual voltage delivered to the device under test. Joulescope has a total voltage drop of 25 mV at 1 A, which keeps your target device running correctly. Joulescope’s extremely fast current range switching maintains low voltage drop even under rapidly varying current demands.
– Makes the invisible visible: Joulescope measures current and voltage 2 million times per second with 250 kHz bandwidth. This high sampling rate makes the power consumption of interrupt service routines, inrush currents and other short events visible.
– Easy to use: Joulescope reports cumulative energy consumption along with real-time current, voltage, and power. The multimeter view clearly shows the most recent value while the oscilloscope view allows you to explore changes over time. Much simpler and more accurate than anything in its class!
