The DT4254-20, suitable for maintenance and upkeep of PV and power equipment, can measure up to DC1700V during the open circuit voltage inspection of solar panels.
The basic accuracy of DC V is ± 0.3%, and the frequency characteristics of AC V are between 40Hz and 1kHz
● Use low-pass filtering to remove harmonics (measurement of the fundamental component of the frequency converter)
● USB communication function corresponding to PC measurement (optional)
● Wide temperature range for use: -10 ℃ to 50 ℃

Accuracy of DMM
Due to its multiple measurement functions and ranges, DMM's basic accuracy is described as a representative value.
Please refer to the sample PDF for the accuracy of each range.

Introduction video of usage methods and functions

This is a video introducing the usage and main functions of the DT4200 series digital multimeter.
HIOKI's multimeter is safe and fast for measurement, supporting the daily work of electrical engineers.

Digital multimeter capable of measuring high voltage up to 1700V DC

The "Standard DT4250 Series" is designed for different purposes for each model.
DT4254 can measure up to 1700V DC, a model suitable for PV and high voltage measurement.
·DC voltage 600.0mV/6.000V/60.00V/600.0V/1000V/1500V
·Equipped with electrical verification function

Can measure the open circuit voltage of megavolt solar energy

Because it can measure up to 1700V DC, it can be used for open circuit voltage inspection of megavolt solar energy.

Notify after determining polarity

When a negative voltage greater than 10V is detected, a red LED and buzzer sound will be used to notify.
It can effectively prevent recording erroneous measurement values.

Removing harmonic components and accurately measuring the output voltage of the secondary of the frequency converter

By using low-pass filtering function, harmonic components can be removed and only the fundamental wave can be measured correctly.

The measurement data is transmitted to the computer, which can confirm and save the data

By using the communication package DT4900-01 in the optional package and connecting it to a computer, the measurement results can be displayed in real-time on the computer. Moreover, the displayed measurement values can be directly saved in text format.
The computer and tester host are isolated through fiber optic communication, ensuring safe measurement.
The software included in communication package DT4900-01 can display charts at specified intervals.

It also has the ability to accurately measure the true effective value of distorted waveforms

There are two measurement methods for a digital multimeter: average value and true effective value.
If the current waveform has a lot of distortion, the measurement results will also vary greatly due to different measurement methods.
In order to make accurate measurements, it is necessary to use testing instruments that use the true significant value method.

Designed/manufactured in Japan, with a reliable 3-year warranty

The development, design, and manufacturing of HIOKI's digital multimeter were all completed at our headquarters in Nagano Prefecture, Japan. We provide high-quality products to everyone with industry-leading technology.

In order to achieve safe measurement, it is necessary to use testing instruments suitable for the measurement site

For the safe use of testing instruments, the safety level standards used as measurement levels in IEC61010 are divided into CAT II to CAT IV according to different usage locations.
Using measuring instruments that do not meet safety standards can lead to electrical accidents.
