KEW FORK 2300R can be used in crowded connection boxes, where cables
are very short, and space is too limited to clamp cables using with a
traditional clamp meter. |

 True RMS (Root Mean Square) Value Measurement |
 |
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.) |
