Many research and productionapplications require low-level voltage measurements to characterize materialsand devices. When signal voltages approach the microvolt ...

Common traits of digital multimeters (DMMs). Classifying DMMs by their amount of digits. What role do digitizers play in making voltage measurements? Measuring voltage may be the most basic ...

A three-point-delta method provides more accurate resistance measurements in low-voltage applications. Electronic components are continuing to shrink as consumers demand faster, more feature-rich ...

I work a lot with high voltages and others frequently replicate my projects, so I often get asked “What voltage is needed?”. That means I need to be able to measure high voltages. Here’s how I do it ...

Imagine a satellite, floating in space. How would you measure its voltage? Yes, it probably has a non-zero voltage, a consequence of geospatial electric fields and ion and electron currents. The ...

A farmer is watering an alfalfa field 24 hours a day using a 3-phase 100-hp electric motor and adjustable speed drive (ASD). The farmer checks on his field to find the water not flowing and the pump ...

Proper calibration of this test equipment is crucial to meeting the strict performance requirements of many high-voltage systems. Calibration results often need to comply with national or ...

Allegro MicroSystems has integrated power, voltage and current monitoring into a single chip with reinforced isolation. Only a handful of resistors are needed to complete the high-voltage interface ...

Patch-clamp recording techniques have revolutionized understanding of the function and sub-cellular location of ion channels in excitable cells. The cell-attached patch-clamp configuration represents ...
