How does Rectifier type instrument work?

The rectifier type instrument converts AC input to unidirectional DC output and then uses a meter responsive to DC to indicate the value of rectified AC. It is primarily a voltmeter. Measurement is carried out on a communication circuit, where voltage is low and resistance is high.

What is Meter Sensitivity?

Meter sensitivity is a measure of the change in total effective resistance in a voltmeter when there is a change of 1V in the full-scale voltage reading. High Sensitivity is desirable in instruments. Highly sensitive instruments produce less error.

How to Calculate DC Meter Sensitivity?

DC Meter Sensitivity calculator uses Sensitivity of DC Meter = 1/Full Scale Current Deflection to calculate the Sensitivity of DC Meter, The DC Meter Sensitivity describes the smallest absolute amount of change that can be detected by a measurement. Sensitivity of DC Meter is denoted by S_dc symbol.

How to calculate DC Meter Sensitivity using this online calculator? To use this online calculator for DC Meter Sensitivity, enter Full Scale Current Deflection (I_fs) and hit the calculate button. Here is how the DC Meter Sensitivity calculation can be explained with given input values -> 9.090909 = 1/0.11.

FAQ
