A digital multimeter is essentially a voltage-measuring tool with some current abilities. A clamp meter is basically a current-measuring tool with some voltage abilities. They are distinctly different instruments, each with its own advantages.
Expert Chuck Newcombe compares digital multimeters of yesterday with today's DMMs with true-rms ac measurement capability. Get the facts about the subtle points you should know when making rms measurements.
- The 189 was the first Fluke handheld DMM that offered two ways to measure AC volts. In the Vac function, the measurement was essentially the same as most Fluke DMMs, but the 189 also allows you to measure ac volts while in the Vdc function.
The most popular reason for paralleling conductors is to provide higher ampacity than a single conductor can provide. "In a typical building design, the largest conductors are usually 500 kcmil or 600 kcmil". "And many electrical contractors will actually object to 600 kcmil. If ampacity above 400 A is necessary, using parallel conductors is the only reasonable solution.
