Digital Multimeter Model: DT-830D, Made in China

  • ·         Small and easy usable yellow color multimeter that work with DC Volt, AC Volt, DCA, hFE 
  • ·         Error Free Measurement
  • ·         Long Lasting Lithium Battery
  • ·         Clear Display
  • ·         Including Stand and Probe


Common Uses:

·         Measuring Voltage (AC/DC):

o   DC Voltage: Measure the voltage of batteries, power supplies, and circuits.

o   AC Voltage: Measure household electrical outlets, appliances, and other AC power sources.

·         Measuring Current (DC):

o   Useful for measuring current in circuits, automotive applications, and electronic devices.

·         Measuring Resistance:

o   Check the resistance of resistors, wires, and other components.

o   Useful for troubleshooting and verifying circuit continuity.

·         Diode Testing:

o   Test the functionality of diodes and semiconductor devices.

·         Continuity Testing:

o   Check if a circuit is complete and continuous. The meter beeps if the circuit is continuous.

·         Transistor Testing:

o   Some models, including the DT-830D, can test transistors by measuring their hFE (DC current gain).

Steps for Using the DT-830D:

  1. Measuring Voltage (DC/AC):

·         Turn the rotary switch to the appropriate voltage range (e.g., 200mV, 20V, 200V).

·         Connect the red probe to the VΩmA port and the black probe to the COM port.

·         Place the probes across the component or circuit where the voltage needs to be measured.

  1. Measuring Current (DC):

·         Turn the rotary switch to the appropriate current range (e.g., 200µA, 20mA).

·         Connect the red probe to the VΩmA port (for lower currents) or the 10A port (for currents up to 10A) and the black probe to the COM port.

·         Place the probes in series with the circuit under test.

  1. Measuring Resistance:

·         Turn the rotary switch to the appropriate resistance range (e.g., 200Ω, 20kΩ).

·         Connect the red probe to the VΩmA port and the black probe to the COM port.

·         Place the probes across the resistor or component to measure its resistance.

  1. Diode Testing:

·         Turn the rotary switch to the diode symbol.

·         Connect the red probe to the anode and the black probe to the cathode of the diode.

·         A typical forward-biased diode should show a voltage drop (typically around 0.7V for silicon diodes).

  1. Continuity Testing:

·         Turn the rotary switch to the continuity testing symbol (often depicted as a sound wave).

·         Connect the probes to the two points in the circuit.

·         The meter will beep if the circuit is continuous.

  1. Transistor Testing:

·         Turn the rotary switch to the hFE range.

·         Insert the transistor's leads into the corresponding hFE sockets (E, B, C) on the multimeter.

·         The meter will display the hFE value.
