The Design of this DC Millivoltmeter presented here is a sensitive dc. electronic meter of several Megaohms input resistance and covering range from 5 Volt f.s.d to 5 mV f.s.d.
This D.C. voltmeter designed to be used with 1 mA meter movement, this unit can be used as a pre-amplifier for a conventional test meter when switched to its 1 mA range for 5 V range. The range of meters from 5V f.s.d ,0.5V, 50mV, and 5mV f.s.d are provided, with input several Mega Ohm.
