Potentiometric Recorder Working Principle (Multipoint): Potentiometric Recorder Working Principle - The thermocouple or millivolt signal is amplified by a non-inverting MOSFET, chopper stabilized, feedback amplifier. This configuration has a very…
XY Recorder Working: XY Recorder Working - In most research fields, it is often convenient to plot the instantaneous relationship between two variables [Y = f(x)], rather than to plot…
Wheatstone Bridge Diagram: A Wheatstone Bridge diagram in its simplest form consists of a network of four resistance arms forming a closed circuit, with a dc source of current applied…
Megger Circuit Diagram: Another common method of measuring resistances above 50 M Ω is the Megger Circuit Diagram (megaohmmeter) shown in Fig. 10.23(a). This instrument is used to measure very…
Fibre Optic CRT Recording Oscilloscope: Fibre Optic CRT Recording Oscilloscope - The familiar CRT oscilloscope has an extremely HF response, but permanent records, normally photography of the screen, cannot be…
Measure of Capacitance and Inductance in Oscilloscope: Measure of Capacitance and Inductance in Oscilloscope - Capacitance may be measured from a capacitor discharge curve. This requires a dc oscilloscope with…
Dual Trace Oscilloscope: Figure 7.19 (a) shows a block diagram of Dual Trace Oscilloscope. This CRO has a single electron gun whose electron beam is split into two by an…
Vertical Amplifier: The sensitivity (gain) and frequency bandwidth (B.W.) response characteristics of the oscilloscope are mainly determined by the vertical amplifier. Since the gain B.W. product is constant, to obtain…
