Let's start with DC voltage, one of the simplest and most-used multimeter measurements. The DC voltage measurement is used to determine the difference in electrical potential between two points in a ...

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 ...

Adigital multimeter (DMM) may look complicated and intimidating at first glance, but once you understand the display, dial, and port panel, you'll have a better grasp of DMM basics. Multimeters come ...

Digital multimeters (DMM), once called voltmeters, have been described as the tape measure for engineers in the new millennium. With electronics and electrical circuits included in almost every ...

Although a power supply and a DMM are fine for some measurements, there are many advantages to having sourcing and measuring in the same instrument. Yet many engineers I encounter are not familiar ...

Measuring AC current (220-V mains RMS current) is not as simple as measuring DC current. In DC current measurement, you can simply hook the oscilloscope probe to the shunt resistor and calculate the ...
