열화상 카메라가 내장된 멀티미터가 필요한 5가지 이유
산업 시스템 및 공정을 안전하고 효율적이며 비용 효과적으로 유지 및 실행하는 일을 담당하는 전기 기술자 또는 엔지니어라면, 문제를 빨리 찾을수록 더 빨리 해결할 수 있다는 것을 알고 있습니다.
멀티미터 열화상 카메라로 문제 해결
사용 가능한 최신 기술은 디지털 멀티미터와 열화상 카메라를 결합하고 무선 기능을 추가하여 안전한 거리에서 측정을 수행하고 저장할 수 있으며 나중에 분석할 수 있도록 테이터를 보관할 수도 있습니다.
클램프 미터와 디지털 멀티미터 비교
디지털 멀티미터는 기본적으로 전압 측정 도구로서 일부 전류 측정 기능이 있습니다. 클램프미터는 기본적으로 전류 측정 도구로서 일부 전압 측정 기능이 있습니다. 이들은 명백히 다른 기구이며, 각각 고유한 장점을 가지고 있습니다.
디지털 멀티미터의 정확도와 정밀도가 중요한 이유
올바른 측정값을 제공하는 멀티미터를 사용하는 것이 중요합니다. 이러한 측정값의 의미를 아는 것은 더욱 중요합니다. 정확성과 정밀도로 측정이 유용할 수 있습니다. 더 높은 정밀도는 더 정확한 반복성을 가능하게 하고 더 높은 정확도는 판독값이 완벽에 더 가깝다는 것을 의미합니다.

How a few good test tools saved motor replacements at a pulp and paper company
Few things are as disposable as paper towels. But the next time you nonchalantly toss away (or compost) a paper towel, keep in mind that there's a lot more to it than meets the eye.
Measuring a rectifier with no load
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.
Solid ground: Increasing parallel conductor ampacity
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.
