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 ...

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 ...

Design engineers use digital multimeters (DMMs) almost every day. They’re the most commonly used instruments on any design engineer’s bench. A DMM could be utilized to make quick and simple voltage ...
