DIGITAL MULTIMETER DT4255

Digital Multimeter with Fuse-protected Terminals Ideal for Harsh Work Environments


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

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 sensor based current measurement eliminates the cause of accidents

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 DT4255 eliminates the root cause of such accidents by providing clamp-on
sensorbased current measurement functionality instead of using conventional probes.
Measure output voltage on the secondary sides of inverters by eliminating harmonic components

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.

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 with peace of mind.
True RMS measurement for accurate measurement of even distorted current waveforms

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

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.

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.
