The Sections of a Multimeter And When To Use it
The electrical multimeter is what a thermometer is to a doctor to an Engineer. Now, can a doctor work without thermometer. One of the first things medical practitioner to their patient is to check their body temperature, Similar, an electrical/electronics Engineer or technician would need to troubleshoot(check temperature if doctor) of a faulty device before taking repair measures. The report of the multimeter determines the repair measure to be executed or component to be changed. Lest we forget, the multimeter comes in two forms, which are the digital multimeter and the analog multimeter.
Basically, there are four major sections in a multimeter which are:
The instrument used in measuring voltage is voltmeter anyways, but it is interesting how the voltmeter is also integrated in the electronic multimeter.
The voltage section still has two subsections, one for measuring alternating voltage(AV) while the other is for measuring Direct voltage(DV). The alternating voltage subsection has the symbol V~ while the Direct voltage subsection has the symbol V—
Also this subsections has voltage magnitude. The average multimeter can measure voltage upto 500V
Yet another section is the current section. Current simply means electron in motion. You can actually measure the electrons in motion a device is using, to do so you would need an ammeter.
However, the ammeter is also integrated in the multimeter. And just like the voltage section, the ammeter section has two subsections which are the direct current subsection with symbol A~ and the alteranting current subsection with symbol A–
3. Resistance Section
Resistance is the measure of opposition to the flow of current right? You can actually determine the resistance of a path using your multimeter. unit of resistance is in ohms
The resitance section has no subsection. This is so because resistance elementary remains the same both for AC and DC. The symbol in the multimeter is
4. Capacitance Section
Capacitance is the ability of a system to store electric charge. While a capacitor is a device capable of storing electric charge; the unit is Farad.
You can measure the capacitance of a capacitor using your electronic multimeter. The higher the capaitance, the more the charge stored in a short time. The symbol is F
The final section which you might not find in all multimeter is the buzz. This is only used for measuring continuity.
Now you have learnt the sections in a multimeter, what next? Come as regular as you could and I would be updating you on how to troubleshoot with multimeter, that’s not all, also other electrical/electronic solutions that would catch your interest.
