The basic steps on how to test house wiring with multimeter,
First, make sure you follow safety rules. Wear rubber footwear and keep your hands dry.
Switch off the main power supply before touching any wires. Check the multimeter and probes for damage. Set the meter correctly before testing.
To check voltage, turn the multimeter to AC voltage mode. Now switch the power on. Place the black probe on the neutral wire and the red probe on the live wire. Look at the display.
If the meter shows a normal reading (around 220 to 240 volts), power is present, and the wiring is working. If the meter shows zero or a very low value, there may be a wiring problem.
Next, turn the power off again. This step is very important. Never test resistance on a live circuit. Set the multimeter to ohms mode.
Touch one probe to one end of the wire and the other probe to the other end. If the meter shows a low value or beeps, the wire is continuous and in good condition. If the meter shows no reading or “OL,” the wire is broken.
You can also test a switch or a socket the same way. Check the voltage when the power is on. Check continuity when the power is off.
Always keep the multimeter on the correct setting. Do not touch the metal parts of the probes. After testing, turn the meter off. A multimeter helps you find wiring problems safely when you use it correctly.
I hope you know now how to check house wiring with a multimeter.

To know how to test house wiring with multimeter, follow these steps;
To prevent unintentional shocks, switch off the main power source.
Ensure the batteries are charged, check the multimeter for damage, and make sure the probes are undamaged.
Select a range greater than the voltage in your house (230V/120V) and set the multimeter to AC voltage mode.
Place the red probe in the VΩ port and the black probe in the COM port.
Touch the black probe to the neutral wire and the red probe to the live wire after temporarily turning the power back on. A correct configuration will display the anticipated voltage.
Place the red probe on the live wire and the black probe on the earth wire to verify grounding; the readings should match the standard voltage.
There may be a problem with the wiring if readings are zero, erratic, or abnormally low.
Turn off the power once more and turn the dial to either resistance or continuity mode to test continuity.
Prior to restoring full power, always wear insulated gloves, keep the area dry, and double-check connections.
