The capacitor meter presented here can measure capacities between 100pF and 1uF on five areas of measurement, more we can say multimeter or tester. Circuit consists of an oscillator with variable ...

Digital multimeters (DMM), once called voltmeters, have been described as the tape measure for engineers in the new millennium. With electronics and electrical circuits included in almost every ...

Magnetic field (Gauss) meter circuit design. The principle of the present meter is shown in the block diagram in Figure 1. The induction coil used to detect the magnetic field is represented by an ...

Most circuit breakers have similar internal structures, which makes the technique broadly applicable. There are two types in the US, according to the Lab: bimetallic thermal and solenoid magnetic. The ...
