Overview
The Hioki DT4256 is a professional-grade digital multimeter designed for electricians and field technicians who need a reliable, accurate tester with a broad range of functions. It belongs to the DT4200 series, offering high safety standards, robust measurement capabilities, and the flexibility to handle both basic and advanced electrical tasks.
It’s especially useful for measuring inverters and systems with high harmonic content because of its low-pass filter, and it supports direct 10 A current input, making it versatile for many test scenarios.
Key Features
| Feature | Description |
|---|---|
| Accuracy | ±0.3% basic accuracy for DC voltage. |
| AC Voltage | Measures from 6 V to 1000 V; supports True RMS, frequency range from 40 Hz to 1 kHz. |
| DC Current | 60.00 mA → 10.00 A direct input. |
| AC Current | 600.0 mA → 10.00 A (True RMS), and with a clamp sensor it can measure up to 1000 A. e |
| Low-Pass Filter | Cuts high-frequency harmonics so you can isolate the fundamental wave — great for inverter measurements. |
| Dual Display | Lets you simultaneously read two parameters (e.g. voltage + frequency). |
| USB Communication (Optional) | Use an optional adapter to connect to a PC and download measurement data. |
| Safety Rating | CAT IV 600 V / CAT III 1000 V — very high safety for demanding environments. |
| Operating Temperature Range | −25 °C to +65 °C (–13°F to 149°F) — works in hot or cold environments. |
| Other Functions | Capacitance, diode test, continuity, max/min/average, relative value, auto hold, and more. |
| Power Supply | 4 × AAA batteries. |
| Build & Durability | Drop‑proof (designed for fieldwork), rugged housing. |
