Theworking principle of Q meteris series resonant because the resonant exists within the circuit once the reactance of capacitance & reactance is of the same magnitude. They induce energy to oscillate in between the fields of electric & magnetic of the inductor & capacitor respectively. This meter...
using an Audio Wattmeter. the name Audio Watt Meter’ is a collective name for all devices that are used to measure the output of an amplifier, so many kinds of equipment fall under this category. What we intend in this project is to create a simple circuit that can measure the output o...
The circuit diagram of the Capacitance Meter using Arduino is shown in below figure. Circuit is simple, aLCD is interfaced with Arduinoto display the measured Capacitance of capacitor. A Square wave Generator Circuit (555 in Astable mode) is connected to Arduino, where we have connected the Ca...
Circuit Diagram and Explanation In thisLC Meter circuit diagram, we have used Arduino to control the project operation. In this, we have used an LC circuit. This LC circuit consists of an Inductor and a capacitor. To convert sinusoidal resonance frequency to digital or square wave we have use...
1.1.1Circuit Diagram Circuit Operation The circuit functioning may be understood with the following points: As we all know that inductors are fundamentally related to generating frequencies or in other words with pulsating or AC supplies. Therefore for measuring such components we need to force them...
Due to varying tolerances of used components, it is vital to perform a calibration exercise. This is used to correct any errors due to varying tolerances. Further details including source code, schematics, and manufacturing files can be found in the EnAccess github repository Infrastructure diagram...
The circuit is built on the back of the panel of a small box. Why brass instead of aluminum? Brass looks classier. The BNC input is at far right in the views of the interior of the meter face, then the 50Ω load and diode rectifier. Above that is the potentiometer. The meter ...
A directional SWR meter is used to measure the magnitude of the transmitted and reflected waves by sensing each one separately, with the help of directional couplers. The circuit diagram of a Directional SWR Meter is shown below. Directional SWR Meter ...
Circuit Diagram: Circuit for thisArduino Sound Level Meteris a very simple in which we have used the LM386 Audio amplifier circuit to amplify the signals from a condenser microphone and supply it to the Analog port of Arduino. We have already used this LM386 IC to build alow voltage audio...
LCR Meter Block Diagram The above block diagram clearly describes the LCR meter connection. In this type of meter, the DC quantities measurement can be done by stimulating the bridge through DC voltage. In contrast, the AC measurements need the Wheatstone bridge excitation through an AC signal. ...
