How to use a Multimeter (Digital multimeter manual)

Digital multimeter manual . Using a multimeter is a little tricky but not si hard as it is considered so far. You just have to figure to some reading basics that may help you take the desired readings. Here we’ll be discussing the manual ranging meter instead of the auto-ranging meter. So you will know how you can set it up to get the desired reading.

A manual ranging multimeter is termed as multimeter because it can gauge a wide range of different types of current and resistance values for your convenience. So, if you want to learn how you can use it perfectly, you should be knowing the basic features and its capacities, so that you will get the accurate readings to help you out in various tasks.

Here are some basic things you may know

The manual multimeter has 4 different settings according to the type of current you want to measure about. One is the V DC which works for the direct current voltage. The second is the V AC that helps in measuring alternating current voltage. There are two options, in which one is A DC which is sufficient to measure Amps obtained from direct current, while another is the OHM gauge that may help you measure the resistances.

All these gauges help in performing various electrical tasks, either you are working with a car to fix its electrical faults or you have to fix some faulty switches, you can make use of the multimeter to gauge the amount of current or resistance that is there.

So, let’s have a look at the various uses of the multimeter and what things are important to consider when you are working with it:

At first, we’ll be seeing a 12-volt battery which is VDC and we’ll be measuring the voltage in the battery using this multimeter. The important things are that when measuring the voltage you will have to adjust the positioning of the meter gauge. So, in this condition you need to take the pointer to the VDC side and set it to the 20 VDC because we are testing a 12-volt battery so the voltage is expected to be within 20 volts. Make sure you don’t adjust the dial below or too high above the expected value as it will not give you the correct reading. In case you try out, you will see nothing or a reading of 1, which indicates that you have adjusted the dial at the wrong position.

You need to put the two leads on the battery having the positive terminal with red lead and negative terminal with the black lead. This will show you the amount of voltage in the battery.

The next use for which the multimeter can be used is to check the voltage in the 120-volt household switch. You will have to adjust the dial to the V AC 200 because it will be below the 200 VAC value. After that, you just have to put one lead in the one hole and the other in the second hole and you will get the reading on your multimeter

The third use of the meter could be the measurement of the resistance. You can check the resistance as if you are checking the resistance of a spark plug. Make sure you set the dial to the approximate value to get an accurate reading.

You can set the dial for 20 K ohms which can cover the resistance range and if you select lower value, you may not get the reading. So make sure select the right value.

You can also check a diode with the help of the multimeter. But in this case, as well, you will have to set the dial to the point at ohms range values, where the diode is indicated and attach the two leads with the two points. In case you get the reading of 1, it means they are connected wrong, but if you get the reading numbers around some value of 500-550, it would indicate that you have connected it correctly and the diode is a good diode. You can also measure the current drawn in amps, from the battery to a headlight bulb.

Conclusion

Mentioning all the uses of this simple gadgets, we can say that it can play an important role in determining the exact value of current flowing in a circuit, either it’s a diode, a battery, a spark plug or a bulb, you can measure what you want to, with a high level of accuracy and precision.
