The DT830D is the most popular, compact, and reliable entry-level digital multimeter used by students, hobbyists, and technicians worldwide. It is a 3.5-digit instrument designed to measure DC and AC voltage, DC current, and resistance with high accuracy. Unlike the basic DT830B, the DT830D model includes a built-in continuity buzzer, which is an essential feature for troubleshooting wire breaks and PCB trace connectivity. Its pocket-sized design and overload protection make it an indispensable tool for every workbench at Robogears.


Key Highlights

  • Essential Troubleshooting: Includes a dedicated Continuity Buzzer that sounds an alarm for low resistance, making it easy to test circuits without looking at the screen.


  • Transistor (hFE) Testing: Features a specialized socket to measure the DC current gain (hFE) of NPN and PNP transistors—a vital feature for circuit design.


  • High Voltage Capability: Safely measures up to 1000V DC and 750V AC, covering everything from small battery projects to household mains.


  • Clear LCD Display: Large digital readout with a maximum reading of 1999, ensuring error-free data collection.


  • Overload Protection: Equipped with internal fuses (typically 200mA/250V) to protect the circuitry against accidental over-current on the lower ranges.

Technical Specifications

  • Input Impedance: 1M$\Omega$

  • Diode Test: Test current ~1mA, Test voltage ~2.8V

  • Signal Output: Built-in square wave generator (approx. 50Hz) for audio testing.

  • Dimensions: ~126mm x 70mm x 24mm


  • Weight: ~150g (including battery)


Prototyping & Installation Tip When measuring high current (up to 10A), ensure the red probe is moved to the "10A" jack and limit the test duration to less than 10 seconds to prevent overheating. For continuity testing, always ensure the circuit power is OFF before touching the probes to the terminals to avoid damaging the meter's internal resistance chip. If the display shows a "1" on the far left, it indicates an Overrange—simply switch the dial to a higher range.
