24 Nov How to test an appliance with a multimeter?
Various electrical problems result in the malfunctioning of appliances and make them stop working. Before assuming that the device is defective and sending it away for repair or throwing it away, you can simply test it with a multimeter. A multimeter is a small handheld tool that is capable of testing the electrical wiring of appliances.
How to test an appliance using a multimeter?
Here’s how you can use a multimeter to test your appliances:
- First of all, turn off the appliance and unplug it to eliminate the risk of electric shock
- Turn your multimeter on and set it at the lowest setting for resistance (ohms). If you are testing an analog device, hold both the probes together and then adjust the needles of the meter to 0.
- Next, access the element of the appliance that you wish to test. This method can vary depending on the type of your appliance. If you are testing a small appliance like a toaster, you will just need to access its plug. On the other hand, if you are testing a larger appliance such as a refrigerator, you might need to remove the panel or its individual components to test them.
- Take alligator clips and attach them to each of the terminals you want to test, such as the leads. For instance, if you wish to test the temperature control of a refrigerator, you will need to pull the temperature control knob away from the wall of the refrigerator and then touch each alligator clip to the terminals of temperature control.
- Then turn the knob of the device as you do while using the device normally. In the case of refrigerator temperature control, you will just have to turn the knob as you do to make the fridge cooler.
- Then read the multimeter. A low reading on the multimeter will indicate that your element is working fine. On the other hand, the infinity/o.L reading or a reading higher than 120 ohms would mean that your element is faulty or defective.
However, you must not test and tag the equipment at your workplace yourself unless you are a qualified technician. Providing a safe environment to your business, clients, and employees is your duty, and you must hire professional help to get your compliance in accordance to the government’s regulations.
