What Is the Potential of Oscilloscopes in Electrical Testing?

The oscilloscope has been a shining example of innovation in electrical testing disciplines for more than 50 years. It has remained a vital tool for scientists, engineers, and professionals working in fields like aerospace and defense ever since it was first developed. In contrast to conventional meters, which only display numerical data, an oscilloscope shows test signals visually, revealing complex characteristics including amplitudes, frequencies, forms, and distortions. This article explores the oscilloscope’s historical significance, development, and essential function in contemporary testing techniques.

Meter Sensitivity and Accuracy

Every meter coil has a certain amount of dc resistance. The amount of resistance depends upon the number of turns on the coil and the size of the wire used to wind the coil. The strength of the magnetic field about a coil increases as the number of turns of the coil increases. Therefore, if more windings are placed on a meter coil, a small current can create a magnetic field strong enough to cause the coil to deflect full scale.

Moving-Coil and Moving-Iron Meter Scales

Scales for Moving-Coil Meters

Moving-coil meter movements have a linear scale; that is, a scale in which the space between numbers is equal. The distance that the pointer deflects across the scale is directly proportional to the amount of current flowing through the meter coil.

Ultimate Resistance Testing Guide

Welcome to the “Ultimate Resistance Testing Guide,” where we’ll dive into the complexities of resistance testing with a streamlined process.

Resistance tests differ from voltage and current tests; they typically involve turning off the equipment and disconnecting its components to guarantee precise measurements. Come along as we examine the several types of resistance tests and discuss the fundamentals of this essential area of electrical testing.
