Description
The Hioki DT4255 is a versatile digital multimeter that combines safety, accuracy, and durability. It features a True RMS measurement capability, ensuring precise readings of both sinusoidal and non-sinusoidal waveforms. The device covers a broad frequency range, from 40 Hz to 1 kHz for AC voltage measurements, making it suitable for various applications, including testing electrical wiring and equipment.
One of the standout features of the DT4255 is its fuse-protected voltage measurement terminals, which significantly reduce the risk of short-circuit accidents—a critical consideration for professionals working in high-voltage environments. The inclusion of a low-pass filter (selectable at 100 Hz or 500 Hz) allows users to isolate the fundamental frequency when measuring inverter outputs or other sources with harmonic components.
The multimeter’s dual display enables simultaneous viewing of primary and secondary measurements, enhancing efficiency during testing. Additionally, it offers a broad operating temperature range of -25°C to 65°C, ensuring reliable performance in various environmental conditions.
For data management, the DT4255 supports USB communication (optional), allowing users to transfer measurement data to a PC for further analysis or record-keeping. This feature is particularly beneficial for documentation and reporting purposes.
