Zeroing in on the right voltage measurement device is critical to achieving the accuracy and speed of measurement required for your voltage measurement task.

While there are other safe methods for measuring line voltage or protecting your oscilloscope, [Jason]’s isolated amplifier method uses high voltage capacitors to achieve isolation.

Physics of wireless voltage measurement All conductive objects have some capacitance, which we can separate into self-capacitance, and capacitance with respect to other conductors. For isolated ...

Find out how a digital technique performs multiplication on two bitstreams and avoids the cost of the analog multiplier.

This project is a great example. [Scott Daniels] takes a look at the other voltage measurement options available to AVR chips used by Arduino.

Theory for Characterizing Capacitance versus Bias Voltage A circuit to measure the DC bias characteristic is shown in Figure 1 .

This is possible in principle, but there’s a drawback: The switching noise generated in a switched-mode power supply can easily couple into a voltage measurement via a shunt resistor.

For more than a century, scientists have relied on separate tools to measure the three core building blocks of electricity: ...

Its measurement frequency bandwidth (-3dB point) is 47 kHz and the DVC 1000-P consumes only 35 mA at no primary voltage when power supplied under +5 VDC. The model weighs only 22g and is more than 60% ...
