With the increasing use of particle accelerators in various fields, construction has developed. In these accelerators, measurement instruments that measure important and versatile quantities are very important. Due to role electric potential acceleration, accurate at any time is essential. this research, design, fabrication testing a non-destructive measuring device called Generating Voltmeter ...

Thousands of dendritic spines on individual neurons process information and mediate plasticity by generating electrical input signals using a sophisticated assembly of transmitter receptors and voltage-sensitive ion channel molecules. Our understanding, however, of the electrical behaviour of spines is limited because it has not been possible to record input signals from these structures with a...

This article discusses the advantages of using a substitution measurement topology in place of the conventional common-current series connection arrangement employed in bridges or potentiometric resistance instruments working at the highest (sub ppm) accuracies. Most high accuracy resistance instruments pass a common AC or DC current through the device-under-test (DUT) and a reference standard ...

We describe the development of a multi-frequency electrical impedance tomography (EIT) system (KHU Mark1) with a single balanced current source and multiple voltmeters. It was primarily designed for imaging brain function with a flexible strategy for addressing electrodes and a frequency range from 10 Hz-500 kHz. The maximal number of voltmeters is 64, and all of them can simultaneously acquire...

Automatic test systems that check components “in-circuit” have reawakened interest in multiterminal techniques for measuring impedance, initially developed for laborato y applications. State-of-theart impedance measurement methods, incorporated in complex bridge configurations, use as many as ‘four-pair” (or eight-terminals “for determining a single component value. Starting with “two-terminal:...
