Analog Multitester Made Simple
The analog multitester is a device that uses a pointer or galvanometer on a predetermined scale. As a portable device, this can be used to read the current, voltage and resistance of the device. This device is used by expert technicians. This device needs to be used properly and read properly so that you can get the accurate reading for electric potential otherwise, you could bust the device upon first use, cause problems due to inefficient reading and this could lead to massive problems to the job you are working on. Using the analog multitester properly can help you resolve countless device issues.
In the digital age, learning how to read the analog multitester is a skill that you can take advantage of. Yes, there are digital options that easier to use but there are some kinds of electrical repairs where the readings can fluctuate. This tester can effectively offer tangible results in your readings. The analog multitester's display is designed like a protractor with several lines and scales. The lower half of the device has a number of knobs that you can use to adjust the measurements. The middle of the display has a very fine piece of metal or needle that points in the left side. Now, the scales are divided into 3 readings. There is the reading for DC, AC and ohms.
Let us get a device first, let's say, a 1.5V DC battery. Dial down your analog multitester up to the tester where it will offer the most accurate reading. The tester will have to wires or leads. The black one is negative and you place it on the negative side. The red lead is to be placed on the positive end. As you dial the meter, you see that the pointer heads in between 1 and 2 meaning it is 1.5. Now, let us check the car battery. Try the same system and the device must point to a 10+2 mark meaning the car battery is 12 volts. You will find that on a functioning device, it will offer the right measurement. Now, if you have made the standard setting and the analog multitester does not give the right reading, the source may have a problem and should be replaced with a new battery.
As said, the analog multitester is best for fluctuating electrical circuits. Let us try now a speaker. Dial the device to DC and place the leads to the proper terminals. Once you have turned the speaker up and the meter lower, you will find the needle bouncing. If you wish to measure pulses and other kinds of moving electrical currents, you need to use the analog multitester since digital testers will not do that for you. As you can see, the analog multitester is a very useful device but if you do not use it properly, you will end up with a lot of problems. It is necessary to learn how to read the scales, make conversions and know where to use it. There are settings you cannot use on one item and there are those you can use on others.
