To check AC and DC voltage with a multimeter, follow these steps:
### Checking DC Voltage:
1. **Set the Multimeter:**
- Turn the dial to the "DC Voltage" setting (usually marked as "V—" or similar).
2. **Connect the Probes:**
- Insert the black probe into the "COM" (common) terminal.
- Insert the red probe into the terminal labeled for DC voltage (often marked as "VΩmA").
3. **Measure Voltage:**
- Place the black probe on the negative side of the circuit and the red probe on the positive side.
- Read the voltage value on the display.
### Checking AC Voltage:
1. **Set the Multimeter:**
- Turn the dial to the "AC Voltage" setting (usually marked as "V~" or similar).
2. **Connect the Probes:**
- Same as for DC: black probe in "COM," red probe in the AC voltage terminal.
3. **Measure Voltage:**
- Place the probes on the AC voltage source (e.g., an outlet or appliance).
- Read the voltage value on the display.
### Safety Tips:
- Ensure the multimeter is rated for the voltages you are measuring.
- Avoid touching the metal parts of the probes while measuring.
- If measuring high voltages, take extra precautions and ensure you’re familiar with safe practices.
Always consult the multimeter's user manual for specific instructions related to your model!
