Five ways to use a digital multimeter

Answer: A digital multimeter can be used to measure voltage, current, resistance, test diodes and capacitance. Instructions for use: Measure voltage: Place the multimeter in the voltage range, connect the test leads to read the voltage value. Measuring current: Connect a multimeter in series with the circuit and read the current value. Measuring resistance: Place the multimeter in the resistance setting and connect the test leads to read the resistance value. Test the diode: Connect the test leads, the positive voltage value will be displayed when forward biased, and the infinity symbol will be displayed when reverse biased. Test capacitance: Connect the test leads and read the capacitance value on the display.

Five ways to use a digital multimeter

1. Measure voltage

• Put the multimeter to the voltage range.
• Connect the red test lead to the positive terminal of the voltage source and the black test lead to the negative terminal.
• Read the voltage value on the display.

2. Measure the current

• Place the multimeter in the current setting.
• Connect the multimeter in series with the circuit.
• Read the current value on the display.

3. Measure the resistance

• Put the multimeter to the resistance position.
• Connect the red test lead and black test lead to both ends of the resistor.
• Read the resistance value on the display.

4. Test the diode

• Put the multimeter to the diode setting.
• Connect the red test lead to the anode of the diode and the black test lead to the cathode.

• Observe the reading on the display:

  • Forward bias: The display shows a positive voltage value (0.5-0.9V).
  • Reverse bias: The display shows the infinity symbol (INF).

5. Test the capacitance

• Put the multimeter to the capacitance setting.
• Connect the red test lead and black test lead to both ends of the capacitor.
• Read the capacitance value on the display.
