We can help you to know what to consider while shopping for the best multi-meter under 100 USD. Let’s dig deeper into our expert buying guide to know what to take into an account.
1. How Much Should You Spend?
At first, ask yourself how much you want to spend even under 100. Your recommended price range will narrow down your choices. Check which brand comes under your budget.
In the case of a multi-meter, you need what is accurate and affordable. Note that a high price doesn't always mean high quality. You can even get the best multi-meter without breaking the bank.
If you are ready to spend anything between 40-60 USD, you can get a great deal. Do you know, even some people think 40USD is too much for a multi-meter. They buy some units at less than 10USD.
You shouldn't be astounded to know that those multi-meters are total crap and don't have proper safety. That's why you have to careful while setting your budget. The expert buyers should not have any issue to find a quality multi-meter at an affordable price.
2. Analog or Digital?
You can also choose another necessary need to make is if you need a digital or analog multi-meter?
Most people prefer using an analog multi-meter over digital units. They find the readouts for better and visible. Also, they claim that the changing trends are easier to see in an analog multi-meter.
However, we found digital multi-meter more useful. Let us explain why! First of all, digital multi-meter features excellent visual readouts, e.g., bar graphs. It goes beyond the three primary measurements.
Also, the efficacy of digital multi-meters can be convenient while working on multiple electronics. We found few issues in an analog multi-meter. For instance, it has a lower impedance, which affects the voltage measurements.
An accurate analog multi-meter is hard to find these days. So, you better check a better digital multi-meter in your price range.
3. Display Count and Rate
No matter what an analog or digital multi-meter, there is a small display unit above. It shows the reading and measurements. The display count is scale-dependent that denotes how large the number displays on the total digits.
The display count should be higher so you can better see the readings. Similarly, the display rate determines how fast the reads on the unit refreshes. More accurate and fast reading comes from a better display rate.
4. Parameters to Look for!
You possibly know that a multi-meter has some essential functions like measuring voltage, current, and resistance. Any multi-meter should do at least these three tasks.
Along with these, a multi-meter should have continuity mode, a diode, and a backlit. Moreover, few units can count extra parameters, including capacitance, inductance, and more. A multi-meter, including all these parameters, comes within 100USD. So, decide your needs and buy accordingly.
5. Auto Ranging or Manual Ranging
Most contemporary multi-meter comes with a feature auto-ranging. It refers to the ability to identify what you are going to test. Here you don’t have to input the range. It is too useful for beginners and students.
With this feature, you don’t have to know capacitance, voltage, resistance, and other values. The multi-meter will do it for you. Conversely, in manual ranging multi-meter, you have to see the range of benefits.
There is no doubt that a multi-meter must provide 100% accurate readings. But, sometimes, there may have few units with imperfect manufacturing and cheap components. Because of this, those unit offers readings with the error.
In that case, you have to be more careful. You need to make sure that the money you spend is well worth it. Read customer feedback if buying online. Also, be prepared to pay extra for a professional-quality multi-meter.
7. Safety Features
When you are using a multi-meter, safety comes first. That is because the multi-meter is going to tackle circuits with more than 30 to 35V. While testing any circuit, there can be any current and voltage ratings.
That's why you should check how it is designed and measurement ratings. Check if it has any shrouded banana plugs on the multi-meter's probes or internal blast shields.
Also, there should have broad flanges to avoid slippage and isolation slots to prevent arc over. Check on the package whether it has these handful features. If that model comes at a bit high price, don't compromise with safety. It’s about your safety, which is way more important.
8. Design and Build-Quality
When it comes to multi-meter design, most people ignore this thing. Folks, you should look at this. Mostly high-quality multi-meter comes with a durable casing and finish. Also, note that the multi-meter with bright orange or yellow keeps it visible.
9. Ease of Use
Finally, your multi-meter should be easy to use, as it is the deciding factor. The features should not be so tough to understand. A decent multi-meter let you decide on selections for variables. It should be usable for both newbie and experts.
How to Use a Multi-Meter?
Once you brought a multi-meter, the first thing comes in mind that how to use a multi-meter? So, if you are getting started, here we will tell you how to use a digital multi-meter.
Mostly a multi-meter includes three essential parts;
1. A display,
2. Selection knob,
1. Know the Symbols:
In the selection knob section, you’ll see a range of symbols and values. You may not need half of them in your projects. Still, it is better to know them for further needs. Here are a few symbols in a multimeter.
1. Direct Current Voltage (DCV): It is used to measure the DC voltage and sometimes denotes as V-.
2. Alternative Current Voltage (ACV): It is used to measure AC voltage from an outlet and sometimes indicates as V~.
3. Direct Current Amperage (DCA): It measures the DC.
4. Resistance (Ω): It measures the opposition in the circuit.
5. Continuity: It tests whether the circuit is closed and if any current is flowing. It usually denotes as diode or wave symbol.
6. Direct Current Gain (hFE): It tests the transistors and its DC gain.
Now, let’s know how to measure voltage, current, and continuity in the following step by step guide.
2. Testing the Voltage
1. Turn on the multi-meter and plug in the probes in their corresponding ports. Here we will measure the voltage on an AA battery.
2. Set the selection knob to the highest setting (say 200V) as you don’t know the voltage range.
3. Now set the black probe on the contrary end and red probe on the positive end of the battery.
Check the reading on display, and it shows 1.6, which means 1.6Volts.
4. For a more accurate reading, you may want to change the selection knob to 20V. It will show the rest readings after the dot, e.g., 1.61V.
5. You can set the selection knob more or less based on the thing you are going to measure.
3. Testing the Current
1. To measure current, you’ll need a series connection. It means you need to interrupt a completed circuit to know the current is flowing there.
2. Here we will measure the current flowing from the battery to the internal circuit.
3. Take two wires of white and red color. Place the red wire at the positive side of the battery and white cable to the negative side.
4. Now interrupt the circuit by cutting in between red wire. Place two probes at two-point and complete the circuit again.
5. Set the setting in the selection knob to a range. Check the multimeter display shows the current that the clock is dragging.
4. Testing Continuity
1. Firstly, turn the selection knob to the diode symbol to check continuity.
See, it shows '1', which means we haven't connected anything to the probes.
2. Now to measure the continuity in any circuit, turn off the power. Connect one probe to one end and other to the other end.
3. If the circuit is completed, then it will show '0' reading. Otherwise, you'll see a value other than 1. In that case, you have to take the necessary step to complete the circuit.
1. Does the Fluke 117 Measure Temperature?
