10 Problems That You Can Solve by Using a Multimeter
There are many uses for a multimeter, which measures current, voltage and resistance in electric devices. Here are some common uses for multimeters, which are helpful for diagnosing technical problems.
Electrical Outlet Concerns A multimeter will help you determine if an AC electrical outlet is providing sufficient output voltage.
Circuit Breaker Issues After switching off all electronic components, flip the breaker back and forth. If there is no voltage on the "on" position, the breaker must be replaced.
Check Washing Machine Condition Find the appropriate button on the multimeter for the RX1 setting to test resistance in the motor of your washing machine. The reading should be close to zero.
Burned Out Lamps A multimeter will assist you in deciding if a lamp has burned out or if there's some other electrical problem.
Faulty Fuses The fuses of many electronic instruments can be tested by setting the multimeter to CONT (continuity).
Check Battery Life You can check the life of various batteries for your car or electronic gadgets.
Measure Resistance in Capacitors By setting the multimeter to Ohms you can find out the resistance level in capacitors.
Identify Hot vs. Neutral Wires To make sure the black wire is hot, you will need rubber gloves to avoid electric shock. The wire is hot if you get a reading when placing the multimeter's prong from the black wire on the bare metal section of the white wire.
Laptop Repair The multimeter can tell you if your laptop needs repair work for problems such as unexpected shutdowns, startup warnings and overheating.
Inspecting AC Thermostats You can check upper and lower thermostats. The upper thermostat needs repair or replacement if the meter reading is near zero, while the lower thermostat reading should be around 120 volts.
Conclusion Many issues with electronic components can be resolved without an electrician by using a multimeter. Learning the values for current, voltage and resistance can help you determine which parts needs to be replaced or what other action needs to be taken to restore the device's performance.
