When measuring electrical current, the goal is to insert an ammeter in series with the circuit so that the current measured by the ammeter is identical to the current flowing through the circuit. In ...

If a product uses power, then power consumption and power quality measurements must be made as part of product design and test. These measurements are essential to optimize product design, comply with ...

CLEVELAND--(BUSINESS WIRE)--Keithley Instruments, Inc., a world leader in advanced electrical test instruments and systems, announced today that the editors of R&D magazine have presented the company ...

MEASURING live voltages and current in today's high-energy environments can result in a severe hazard to equipment and users if proper precautions are not applied. Given the risk of transients, surges ...

Measuring current is always a nuisance because you have to break the circuit to put the measuring device in series with the circuit. That problem never goes away. Still, any high-end digital ...

One application that uses a precision power supply and DMM involves characterizing the current drawn by a device or circuit board at different voltage levels. Figure 1 shows a typical setup. Engineers ...
