One of the most vital tools in your toolbox—both physically and in terms of your know-how and experience—is a digital multimeter. A lot of people are leery working with electricity, and for a good reason: electricity could be risky when working on any appliance. Knowing when you are doing something right or wrong can be quite a challenge.
Many appliances with electrical parts go bad when some circuit components are no longer conducting electricity properly. Hence, being able to isolate the parts and test them will be a frequent part of your task.
The capability to measure resistance, current, and voltage all using the same tool—an Etekcity Multimeter is still a wonder if you think about it. Owning a properly functioning multimeter—with some smart features such as memory and hold—is essential to the success of any electrical or electronic project.
Nonetheless, it’s also crucial to own a multimeter that’s well-fitted for your particular tasks.
Are you currently searching for a good quality multimeter to replace your old measurement device? Look no further because this is where Etekcity Multimeter comes to the rescue.
What is the Etekcity Multimeter?
Etekcity is a company that has established a reputation for manufacturing quality products without costly price tags. Their digital multimeters like the Etekcity Multimeter MSR-A1000 have many of the features and protections desired by users, not to mention you don’t need to pay extra for them.
The Etekcity Multimeter is big enough to include all the important options but small enough to be simple to use and carry. The DMM includes features that make it hassle-free to use, like a big LCD screen display. Further, it has a hook to clip the device out of the way, as well as a rotary dial that’s simple to use.
The Etekcity Multimeter was created with safety in mind. The best part here is that an automatic shutoff feature restores the batteries. You will find a non-contact voltage mode, allowing you safely test potentially live or hot wires without any direct contact.
Did you know that this digital multimeter offers overload protection and reverse polarity protection? How amazing is that? The Etekcity Multimeter also features two ceramic tube fuses instead of a single ceramic tube fuse that most DMMs use for protection purposes.
In case you didn’t know, Etekcity was in the world of business way back in 2011. The company was established to offer its consumers practical, robust products at affordable prices. This ecommerce retail company has established a global presence, along with many happy customers situated all across the globe.
Testing Voltage with Etekcity Multimeter
Etekcity Multimeter measures DC and AC voltages. Keep in mind that car batteries supply DC voltages, while wall outlets inside your home supply AC Voltage. Further, DMMs offer you measurements on a digital screen.
Here are the steps you need to do to test a voltage with your digital multimeter.
- Choose either DC or AC volts on your Etekcity Multimeter. Are you testing a car security installation or a car stereo? Then you need to test for DC voltage. Set your Etekcity Multimeter to the correct range for the voltage you want to find.
In a car, that would be around twelve to fourteen volts DC. In your home, you will get at least 120 volts of AC. If you measure an unknown voltage, choose the highest range and work down.
- Attach the negative lead to a known ground and touch the positive probe to the wire you are testing. For exact readings, ensure the ground is bare metal.
- Now, see the reading on the meter’s display.
Testing and Measuring Current with Etekcity Multimeter
Current or amps is the electrical charge flow through a conductor or component. Current is measured in amperes or amps.
- Remove the power source before you start testing.
- Remove the completed circuit at the end of it.
- Put the multimeter in series along with the circuit.
- Reattach the power source and turn it on.
- Choose the highest current setting, and you can start your work way down.
Testing for Continuity
A circuit is said to have continuity if it has a path through which electricity can flow. Keep in mind that a circuit with continuity is called “closed.” If the current can’t flow due to a break in the circuit or extremely high resistance, the circuit is often known to be “open” or to have continuity. Testing for a continuity enables you to determine whether a circuit is closed or open.
- Turn off the circuit’s power. You will damage your Etekcity Multimeter if the voltage source is connected to the circuit during the test.
- Choose resistance on your Etekcity Multimeter. Touch the tips of the probe across the component or portion of your circuit for which you like to determine the continuity.
- Read the readings on your Etekcity Multimeter. If the reading is low, it indicates you have continuity. If the reading is infinity, it indicates there’s no continuity. Thus, the circuit is open.
Testing for Resistance
Resistance is measured in ohms. It will tell you how much circuit resistance the electric current flows against. Resistance values could differ substantially, from several milliohms for contact resistance to billion ohms for insulators.
- Turn off the circuit. Take note that a resistance test should be done with the circuit power off. Or else, it may lead to damage to your Etekcity Multimeter or circuit.
- Choose “ohms” on your meter.
- Touch the probe tips across the portion of the circuit or component you like to measure the resistance. For a precise reading, ensure to detach the measured component from all other parts. Ensure you also don’t touch the metal probes with your fingers. The resistance within your body will only confuse the Etekcity Multimeter and give you an incorrect reading.
- Read your Etekcity Multimeter. Ensure you read the unit of measurement on the display of your meter.
You see, electricity performs an integral role. Still, the current and voltage by which electricity is measured can’t be seen directly. How can such things be observed with a bare-naked eye? Resistance, current, and voltage can all become observable if you use your Etekcity Multimeter properly.
