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 DT4255 is a digital multimeter designed for maximum safety with voltage measurement terminals that are protected by a fuse. CAT IV 600 V, CAT III 1000 V Key Features • Prevents short-circuit accidents with a fast-blow fuse and current-limiting resistor (DT4255) • Prevents accidents with clamp-on sensor-based current measurement (DT4254, DT4255) • Voltage detection function (DT4254, DT4255) • Low-pass filter cuts high harmonics (when measuring inverter fundamental waveforms) • Broad -25°C (-13°F) to 65°C (149°F) operating temperature range (DT4254, DT4255) • Dual display lets you check voltage and frequency simultaneously

Thorough prevention of shortcircuit accidents
When using the resistance measurement function, a protective circuit functions to prevent a short-circuit accident in the event of erroneous operation such improperly supplying voltage input. Even if a short-circuit occurs inside the tester, a current-limiting resistor will limit any short-circuit current while a fast-blow fuse quickly and reliably disconnects the tester circuitry, preventing a short-circuit accident.
Clamp-on sensorbased current measurement eliminateｓ the cause of accidents
Mistakenly measuring voltage using the current range may lead to a short-circuit. The DT4255 eliminates the root cause of such accidents by providing clamp-on sensorbased current measurement functionality instead of using conventional probes.
Measurement data can be downloaded to, reviewed on, and saved to a computer.
If you connect the DT4255 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.
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.
