FET VOLTMETER


Posted on Feb 5, 2014

A2N3819 FET provides a solid state VOM ‚The 2N3819 acts as a cathodefollowerin a VOM The biasoffset(meter null) is obtained with R14 and R12 sets full scale calibration R2 through R9 should totalabout10 M © R10 is a protective resistor and C2 provides ac bypassing to limit rf and noise pickup
