Yes it is necessary to calibrate the tester first before you use it so it would properly work.

In order to maintain this in a good condition you just need to keep it a safe place and clean it for some time.

There are tools that created for a designated use to make things easier for us. Say example are you gonna use a hacksaw to cut a paper? just because it will work too. Very Happy I bet you won't that's why they created the scissor.

Yes we also have ammeter for the current.

and we also have multitester. These multitester is composed of ammeter, voltmeter and ohmmeter.

Yeah! That's right. Smile
or VOM the combination of voltmeter,ohmmeter and the milli ammeter

for me as a beginner i want to use the digital becuase it is easy it is easy to measure but but now i want to use analog beacuase although it is not easy but it is accurate.

first, you have to look at pointer if it is at the zeroand if it is...then use the range selector to how adjust the range put the test probe components and it gives you the reading

To used it properly you always need to check the pointer if it is located exactly 0 if it is not then you need to adjust it by zero ohm adjustment knob if it we only tend to measure the resistance.

What is parallax error?

a parallax error occur when theres an improper viewing position or when viewing an object at an oblique angle

Parallax is an apparent change in the position of an object when the person looking at the object changes position or line of sight. In meter reading, this error occurs when your line of sight is not perpendicular to the plane of the meter dial. Rolling Eyes

If you want accurate measurement, it is much more advisable if you will use digital tester.

Me too! I'm in favor of using digital tester (even though im using analog). It offers you more accurate readings.

If I'm using a voltmeter, and I want to measure the voltage output of the outlet. Is it advisable for me to directly connect the probes to the outlet?
