The Digital Multimeter DT-830B is a compact, pocket‑sized 3½‑digit multimeter designed for measuring DC and AC voltage, DC current, resistance, and performing diode and transistor tests. Renowned as one of the most affordable multimeters worldwide, it is ideal for students, hobbyists, and beginners working with low‑voltage circuits.
Key Features
- 3½‑Digit LCD Display (1999 Counts) – Large, easy‑to‑read LCD screen with a maximum reading of 1999. The display includes low‑battery indication and automatic polarity display.
- Wide Voltage Measurement – DC voltage up to 1000V, AC voltage up to 750V. Both ranges have overload protection for safe operation.
- DC Current Measurement – Measures DC current from 200 µA up to 10 A. The 10 A range is ideal for automotive and battery applications.
- Resistance Measurement – Resistance ranges from 200 Ω up to 2 MΩ, sufficient for most hobbyist and repair tasks (200 Ω / 2 kΩ / 20 kΩ / 200 kΩ / 2 MΩ).
- Diode & Transistor Testing – Built‑in diode test and hFE test socket for NPN and PNP transistors, allowing quick semiconductor checks.
- Overload Protection – Overload protection on all ranges helps prevent accidental damage during misuse.
- Low Battery Indication – Automatic low‑battery indicator warns when the 9 V battery needs replacement.
- Compact & Portable – Lightweight (≈150 g) and small enough to fit in a pocket or toolbox, ideal for field use and bench work.
- Backlight Display (on most variants) – Some variants include a backlight for improved visibility in low‑light environments.
- Data Hold Function (on some models) – Freezes the current reading on the display for easy recording.
