Battery Operated Auto Ranging DVM

Related Page - Battery Operated Auto Ranging DVM with the ICL7106

This application note describes a technique for auto-ranging a battery operated DVM suitable for panel meter applications. Also, circuit ideas will be presented for conductance and resistance measurement, 9V battery and 5V supply operations, and current measurement. The control signals necessary for auto-ranging are over-range, under-range, and clock. The over-range and under-range inputs control the direction of a scale shift, becoming active ....

Microwave networks are harder to analyze than their lower-frequency counterparts. The reason is that the size of a typical microwave circuit is comparable the wavelength, so phase variation along a portion of the circuit cannot be ignored as is the case at lower frequencies.
