Description
The Hioki DT4200 Digital Multimeter Series consist of a complete lineup of 9 models ranging from professional to industrial to pocket meters, delivering a super fast response rate and safety features that take electrical testing to a higher level. The DT4256 is a digital multimeter designed to deliver maximum functionality for use in a wide range of settings.
CAT IV 600 V, CAT III 1000 V
Easily Transfer Measurement Data to a PC
If you connect the DT4256 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 without concern for electrical hazards.
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.
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.
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.
