FET Voltmeter 3040

Categories: Instrumentation


* Completely self contained stand – alone unit.

* Demonstrates the principle and working of a FET voltmeter.

* Supply required 230V, 50Hz AC.

* Built – in IC based DC regulated power supply with short circuit protection and LED indication for supply “ON”.

* Built – in two range voltmeter ( 0.5V & 1.0V f.s.d ).

* Built – in FET unity voltage gain buffer amplifier for high input impedance.

* Built – in bridge circuit for zero quiescent voltage across meter.

* Built – in source follower for minimum drift with zero correction potentiometer.

* Helps in understanding the advantage of FET voltmeter over regular analog voltmeter.

* Multi – coloured test points are provided at various stages in the circuit to observe the waveforms and voltages.

* Housed in an elegant cabinet with a well spread intelligently designed circuit layout on the front panel.

* Strongly supported by a comprehensive instruction manual complete with theory and operating details.
