( Actual Size )Capable of measuring AC and DC current up to 100Awith the newly developed open current tester• True RMS reading is an essential feature for accurate measurement (see rear page).
• " 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• Auto Power Off• Data Hold (AC A / DC A only)• Designed to international safety standard IEC61010-1 CAT.3 300V
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
Averaging Value

True RMS Value

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 isaffected by some distortions such as inverter, etc ,averaging value type clamp meter indicates 5.5A instead of 9.7A and true RMS typeclamp meter indicates 7.9A instead of 9.7A with irregular wave-form. Accordingly, true RMS type clamp meter is recommendable for themeasurement of the equipment with inverter
control devices.

Instruction Manual, R03 (AAA) × 2, Carrying CaseDue to the use of thyristors, inverters and otherenergy-saving controllers in recent electric wiring,
current waveforms often include harmoniccomponents and are distorted compared tosinusoidal waves (50/60Hz).
The Kyoritsu True RMS value tester is able tomeasure distorted waveforms using true RMS
since waveforms are being internally calculatedcontinuously. In contrast, when measurements
are made with a averaging value tester, errors are
generated in the measurement value because thetester cannot continuously track distortedwaveforms.
(Compared to the true RMS value tester, measurement values forthe averaging value generate more than 30% errors in some cases.)Crest Factor
The ratio of peak value to root mean square value,
expressing the dynamic range. The crest factor on anundistorted sinusoidal wave is 1.41. Any value outside of thismeans that the waveform is considered to be distorted.

Please read the "Safety Warnings" in the instruction manual supplied with the instrument thoroughly andfor correct use. Failure to follow the safety rules can cause fire, trouble, electrical shock, etc. Therefore,
Safety Warnings : completely
make sure to operate the instrument on a correct power supply and voltage rating marked on each instrument.
