Introduction to Oscilloscopes: Introduction to Oscilloscopes - The Cathode Ray Oscilloscope is probably the most versatile tool for the development of electronic circuits and systems. The Cathode Ray Oscilloscope allows…
Microprocessor Based Instruments: Microprocessor Based Instruments - Digital instruments are designed around digital logic circuits without memory. The use of microprocessors as an integral part of measuring instruments has given…
Digital Capacitance Meter Block Diagram: Digital Capacitance Meter - Since the capacitance is linearly proportional to the time constant, when a capacitor is charged by a constant current source and…
Different Modes of Operation of Electronic Counter: The decade counter can be easily incorporated in a commercial test instrument called an electronic counter. A decade counter, by itself, behaves as…
Successive Approximation Type DVM: The Successive Approximation Type DVM principle can be easily understood using a simple example; the determination of the weight of an object. By using a balance…
Dual Slope Integrating Type DVM (Voltage to Time Conversion): Dual Slope Integrating Type DVM - In ramp techniques, superimposed noise can cause large errors. In the dual ramp technique, noise…
Working Principle of Multimeter: A multimeter is basically a PMMC meter. To measure dc current the meter acts as an ammeter with a low series resistance. Range changing is accomplished…
Multirange Ohmmeter: The Multirange Ohmmeter circuit shown in Fig. 4.28 (a) is only for a single range of resistance measurement. To measure resistance over a wide range of values, we…
