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

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

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.

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 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

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.
