The ultimate digital multimeter, ideal for use R&D applications
The DT4282, which is part of Hioki’s DT4280 series of high-end digital multimeters, is designed for use in
laboratories and R&D applications where you wish to measure a wide variety of parameters.

・ DC current 600.00μA / 6000.0μA / 60.000mA / 600.00mA /6.0000A / 10.000A
・ AC current　600.00μA / 6000.0μA / 60.000mA / 600.00mA /6.0000A / 10.000A
・ Conductance　600.00nS

Measure output voltage on the secondary sides of inverters by eliminating harmonic components
Accurately measure the fundamental wave alone by eliminating harmonic components with the DMM’s
low-pass filter function.

Measure ripple voltage of DC charging systems
You can measure ripple voltage with a superposed DC signal by using peak value measurement and
DC + AC voltage measurement.

Percentage display for 4 to 20 mA instrumentation signals
The digital multimeters can convert and display instrumentation signals of 4 to 20 mA or 0 to 20 mA
representing properties such as temperature, pressure, and flow rate from a transducer or other device
that converts sensor data into an electrical signal.

600.00 μA range for measuring very low currents used by gas-burning devices
Accurately measure the very low currents such as burner flame currents.

True RMS measurement for accurate measurement of even distorted current waveforms
Digital multimeters implement two types of measurement: mean-value measurement and true RMS
measurement. The two methods yield significantly different measurement results for current waveforms,
which are often distorted. For accurate measurement, it is necessary to use an instrument with true RMS
capability.

Measurement data can be downloaded to, reviewed on, and saved to a computer.
If you connect the DT4282 to a computer with the optional Communication Package DT4900-01,
you can graph data stored in the instrument’s internal memory and display measurement results in
real time on the computer. In addition, displayed measured values can be saved (in text format).

*Use of optical communications keeps the computer and instrument electrically isolated to ensure safety.

*The computer and multimeter are electrically isolated by means of optical communications so that data
can be sent without concern for electrical hazards.

Designed and manufactured in Japan to ensure high quality and guaranteed with a 3-year warranty 
All development, design, and manufacturing processes for almost all Hioki digital multimeters are
carried out at our Head Office in Nagano Prefecture. Some of the industry’s most advanced technological
capabilities enable us to deliver products of the highest possible quality

Safe measurement requires use of an instrument that suits the measurement location.
To ensure operators’ ability to use measuring instruments safely, IEC 61010 classifies the locations in
which instruments are used into a series of safety-based measurement categories (ranging from CAT II to
CAT IV). Using an instrument that does not satisfy the required safety level can lead to an electrical accident.
