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.
Measurement data can be downloaded to, reviewed on, and saved to a computer.
If you connect the DT4252 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). *The computer and multimeter are electrically isolated by means of optical communications so that data can be sent with peace of mind.
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.
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.
