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.
솔리드 접지: 병렬 도체 전류 용량 증가
병렬 도체가 필요한 가장 일반적인 이유는 단일 도체가 제공할 수 있는 것보다 더 높은 전류용량을 제공하기 위해서입니다. Divine은 "전형적인 건물 설계에서, 가장 큰 도체는 보통 500kcmil 또는 600kcmil입니다. 그리고, 많은 전기 계약자들은 실제로 600kcmil에 반대할 것입니다. 400A 이상의 전류용량이 필요한 경우 병렬 도체를 사용하는 것이 유일한 합리적인 솔루션입니다. 실제로 병렬 연결을 위한 1/0AWG 도체의 하한은 시설의 전기 설계에 큰 영향을 미치지 않습니다."라고 말했습니다.

Troubleshooting with the Fluke 116 Multimeter
Read success stories from ONSITE PC Assitance owner Robert Johns. Working on mostly low voltage equipment for home offices and small-to-medium business, Johns uses the Fluke 116 to measure for low voltage, auto-ranging and min/max temperature.
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.
