The presented circuit measures currents and voltages with precision that depends on the tolerance of the resistors used. The instrument is a microammeter and more scales can be added.
This old circuit, from the 80s, was found in American documentation. The circuit uses dual gate...
The value of R1 given by I = R1 / 5 determines the load current of this circuit. The maximum...
