When load current is not affected by the distortion, both averaging value type and true RMS (root mean square) type clamp meters show the almost same value of about 10A with constant wave-form as the above display samples. However, when load current is affected by some distortions such as inverter, etc...,averaging value type clamp meter indicates 5.5A instead of 9.7A and true RMS type clamp meter indicates 7.9A instead of 9.7A with irregular wave-form. Accordingly, true RMS type clamp meter is recommendable for the measurement of the equipment with inverter control devices.
Due to the use of thyristors, inverters and other energy-saving controllers in recent electric wiring, current waveforms often include harmonic components and are distorted compared to sinusoidal waves (50/60Hz).
The Kyoritsu True RMS value tester is able to measure distorted waveforms using true RMS since waveforms are being internally calculated continuously. In contrast, when measurements are made with a averaging value tester, errors are generated in the measurement value because the tester cannot continuously track distorted waveforms.
(Compared to the true RMS value tester, measurement values for the averaging value generate more than 30% errors in some cases.) | |

1 전압감지기능(NCV:Non Contact Voltage)
전선, 전극등에 접촉하지 않고 전압의 유무를 확인하는 기능입니다. (케이블. 콘센트.휴즈. 회로차단기. 배전반등에서 안전하게 AC전압의 존재를 간단히 확인할수 있습니다.)
2 CF(파고율)
파고치와 실효치를 비교하는데 있어 다이나믹렌지의 넓이를 나타냅니다. 파고율은 파형 왜곡없이 정현파로서 1.41입니다. 이 값에서 벗어나면 파형이 왜곡되었다는 의미입니다 | | |
