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 ....

It is important to understand the difference between accuracy and precision. Using the simple analogy of a game of darts, accuracy is consistently hitting the true mark, or bull’s-eye. Precision is consistency, but not necessarily accurate consistency. This fact sheet provides information on the types, use, and calibration of temperature measuring devices.

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.
