  1. Circuits Measurement Maxim MAX4172 MAX495
    Although an analog moving-coil meter may lack the resolution and accuracy that a digital readout provides, a meter remains the display of choice for certain applications. A digital readout simply cannot provide information about a measurement's ...

  2. Circuits Measurement Maxim MAX4172 MAX495
    A previous Design Idea describes an interesting and useful method for using a moving-coil analog meter to measure currents in the less-than-1A range ( Reference 1 ). The design offers considerable flexibility in the choice of meter-movement ...
