Study Notes
Multimeter Use
Measuring Voltage
- Types of Voltage Measurement: AC (Alternating Current) and DC (Direct Current).
-
Setting Up:
- Turn the multimeter dial to the appropriate voltage type (AC or DC).
- Select the correct range if the multimeter is not auto-ranging.
-
Connection:
- Connect the black lead to the COM (common) terminal.
- Connect the red lead to the VΩmA terminal.
-
Procedure:
- Place the probes across the component or circuit.
- Read the voltage on the multimeter display.
Current Measurement
- Types of Current Measurement: AC and DC.
-
Setting Up:
- Turn the multimeter dial to the appropriate current type.
- Select the correct range if needed.
-
Connection:
- Disconnect the circuit to insert the multimeter in series.
- Connect the black lead to the COM terminal.
- Connect the red lead to the A terminal (or mA for smaller currents).
-
Procedure:
- Reconnect the circuit ensuring the multimeter is in series.
- Read the current flowing through the circuit on the display.
Continuity Checks
- Purpose: Verify if a circuit is complete; useful for detecting broken connections.
-
Setting Up:
- Turn the multimeter dial to the continuity setting (often indicated by a sound wave or diode symbol).
-
Connection:
- Connect the black lead to the COM terminal.
- Connect the red lead to the VΩmA terminal.
-
Procedure:
- Touch the probes to the two points of the circuit.
- If there is continuity, the multimeter will beep or show a low resistance value.
- Note: Ensure power is turned off before performing continuity checks to avoid damage to the multimeter.
Measuring Voltage
- Types of Voltage: Two voltage measurements are commonly used: AC (Alternating Current) and DC (Direct Current).
- Setup Process: Set the multimeter to the relevant voltage type (AC or DC) and select the correct measurement range unless using an auto-ranging model.
- Lead Connections: Connect the black lead to the COM terminal and the red lead to the VΩmA terminal.
- Measurement Procedure: Place the probes across the component or circuit to measure voltage, then read the result displayed on the multimeter.
Current Measurement
- Types of Current: Measurements can also be taken for AC and DC currents.
- Setup Process: Set the multimeter to the appropriate current type and range as necessary.
- Circuit Connection: Disconnect the circuit to insert the multimeter in series; ensure the circuit is opened before connecting.
- Lead Connections: Connect the black lead to the COM terminal and the red lead to the A terminal (or mA for smaller currents).
- Measurement Procedure: Reconnect the circuit, confirming the multimeter is in series, and observe the current flow on the display.
Continuity Checks
- Purpose: Used to check if a circuit is complete; essential for identifying broken connections within the circuit.
- Setup Process: Rotate the multimeter dial to the continuity setting, often marked by a sound wave or diode symbol.
- Lead Connections: Connect the black lead to the COM terminal and the red lead to the VΩmA terminal.
- Testing Procedure: Touch the probes to two points in the circuit. If continuity exists, the multimeter will produce a beep or display a low resistance value.
- Safety Note: Always turn off power before performing continuity checks to prevent damage to the multimeter.
