DIGITAL MULTIMETER DT4254

Digital Multimeter for Efficiently Maintaining Power Equipment, PV and Megasolar Devices


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 DT4254 is a voltage measurement only model designed for measuring photovoltaic modules and other high-voltage targets up to 1700 V DC (*1).

CAT IV 600 V, CAT III 1000 V

Key Features

• The voltage measurement model, which is ideal for solar power system and power equipment management, measures up to 1700 V DC (*1) during open voltage inspections (DT4254)

• 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

*1 Your instrument can be used to measure voltages in excess of 1000 V DC if and only if both of the following conditions are satisfied: 1. The circuit under measurement is isolated from the commercial power grid. 2. The circuit under measurement is isolated from ground.

 

High-voltage measurement digital multimeter that measure up to 1700 V

The DT4254, which is part of Hioki’s DT4250 series of standard digital multimeters, is ideal
for measuring photovoltaic modules and other high-voltage targets at up to 1700 V DC.

・ DC current 600.0mV / 6.000V / 60.00V / 600.0V / 1000V / 1500V

・ Voltage detection function

Test no-load voltage at megasolar installations

Test no-load voltage at megasolar installations

The DT4254 can measure DC voltages up to 1700 V, enabling you to make no-load
voltage inspections of megasolar installations.

Polarity detection and notification

Polarity detection and notification

The DT4254 can detect a load voltage in excess of -10 V and notify the operator with
a red LED and beep. This feature helps prevent recording of erroneous measured values.

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 DT4254 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

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

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.
