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 ....
Here is a Simple Voltage and Current Regulated Power Supply using the LM723 IC. With the Values Shown, It is Adjustable from 3 to 30 Volts and 0 to 3 Amps. This circuit does NOT have Output SHORT CIRCUIT Protection, So a 3 Amp Fuse on the Output would be a Good Idea. Ideally you will put an Amp-Meter,
Temperature is one of the most frequently measured parameters in industrial processes. A wide variety of mechanical and electrical thermometers are used to sense and control process temperatures. Regular calibration of these thermometers is critical to ensuring consistent quality of product manufactured, as well as providing regulatory compliance for some industries.
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.
