Magnetic Tape Recorder Working Principle: The major advantage of using a Magnetic Tape Recorder Working Principle is that once the data is recorded, it can be replayed an almost indefinite…
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…
Null Type Recorder: These Null Type Recorder Working Principle of self-balancing or null conditions. When an input is given to the measuring circuit of the recorder from a sensor or transducer,…
Detectors Types: The Detectors Types are as follows For low frequency, the most convenient detector is the vibration galvanometer. For ordinary laboratory work at frequencies up to a few 100 Hz,…
pH Measurement Methods: pH is defined as the negative logarithm of the active hydrogen ion. It is a measure of the acidity or alkalinity of an aqueous solution. The pH…
Transistor Tester and its characteristics: The term Transistor Tester (or analyser) used in this text is for instruments giving quantative measurements of transistor parameters. The tester should be able to…
RX Meter Circuit in Measuring Instruments: An RX Meter Circuit in Measuring Instruments is used to measure the separate resistive and reactive components of a parallel Z network. It is…
