| • |
True RMS reading is an essential feature for accurate
measurement. |
| • |
“Non Contact” voltage function indicates
the presence of AC voltage by warning the user with an audible signal. |
| • |
Set the DC current range to zero in one touch with
the Zero Adjust function. |

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.) |
