Thoroughly prevent accidental short circuit accidents
Thoroughly prevent accidental short circuit accidents
By using the resistance measurement function, the protection circuit plays a role in preventing short circuit accidents when voltage is inputted due to misoperation. In case of a short circuit inside the multimeter, the current limiting resistor will control the short-circuit current, and the fast tripping fuse can quickly and completely cut off the circuit, thereby preventing short circuit accidents.
Measure current through clamp sensors to eliminate the cause of danger
Measure current through clamp sensors to eliminate the cause of danger
When measuring voltage within the current range, a short circuit accident may occur.
By using clamp sensors for current measurement, the cause of short circuits can be fundamentally eliminated.
Removing harmonic components and accurately measuring the output voltage of the secondary of the frequency converter
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
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 effective 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. To provide high-quality products to everyone with advanced technology in the industry.
In order to achieve safe measurement, it is necessary to use testing instruments suitable for the measurement site
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.
