How to use digital multimeters
This video introduces how to use the DT4280 series of digital multimeters as well as some of the instrument’s featured functionality. Hioki multimeters are engineered to help professional electricians do their jobs safely and quickly.
The ultimate digital multimeter, featuring a design focused on safety that’s critical for electrical work
The DT4281, which is part of Hioki’s DT4280 series of high-end digital multimeters, is designed for maximum safety in electrical work. Connect an AC clamp to safely measure current.
Accurately measure the voltage output from the secondary sides of inverters by eliminating harmonic components
Measure the fundamental wave alone by eliminating harmonic components with the DT4281’s low-pass filter function.
Measure the ripple voltage of DC charging systems
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 multimeter 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.
Clamp-on sensor based current measurement eliminates the cause of accidents
Mistakenly measuring voltage using the current range may lead to a short-circuit. The DT4281 eliminates the root cause of such accidents by providing clamp-on sensor based current measurement functionality instead of using conventional probes.
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.
Connect the DT4281 to a PC with the optional Communication Package DT4900-01 to easily graph data stored in the DMM’s internal memory and display measurement results in real time on the computer. Save important measured values in text format.
Designed and manufactured in Japan to ensure high quality and guaranteed with a 3-year warranty for peace of mind
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.
