Q7: When was the multimeter invented?
The multimeter came onto the market in 1923, so its creation was a couple of years earlier. It arose as a response to the need to unify the functions of three devices, the ammeter, the voltmeter and the ohmmeter into one, to simplify work. His invention is entrusted to the engineer Donald MacAdie and was called Avo. In its beginnings, it was a device for direct current circuits And over the years new functions were added, being possible to measure alternating current. Later, the digital prototypes came onto the market, whose basis of operation is the same as the analog ones. However, they do include other features for troubleshooting electrical problems.
Q8: Why doesn’t my multimeter sound?
There could be several reasons why the multimeter is not beeping. One of them may be that it does not have this option within its functions or that this property is broken. Another simpler reason may be due to the fact that the measurement is in direct current. The buzzing usually starts when continuity is measured with values between 0 and 10 ohms. In the 2K resistors there are more ohms and it will not ring.
How to use a multimeter
A multimeter is a device that is used to measure current and is usually a widely used device today. Due to the fact of having contact with electrical current, great care must be taken in handling. Next we will give you some indications to use a multimeter properly.
Identify the multimeter
Before starting to measure, it is necessary to review what type of multimeter will be used, whether digital or analog. Next, it is necessary to identify the kind of measurement that will be carried out, whether it is current or resistance.
Read the manual carefully
Before starting to work with a multimeter it is important to read the manual and know the maximum voltage capacity, as well as the specifications of the equipment to avoid accidents.
Select the function
By turning the knob, which is usually in the middle of the device, a function can be selected according to what is going to be measured, such as temperature, direct voltages, alternating voltage, alternating current amperage, resistance or others.
connect the probes
For this step it is necessary to be careful and connect the probes correctly: the black one in the general socket and the red one in the socket to measure the voltage. Next, the other side of the probe must be connected to the object. Some models are able to show if there is reversed polarity and in this case the cable entry must be changed.
Measures alternating voltages and others
In case of measurement for alternating voltages, the knob must be placed in the measurement of alternating voltage and the probes in the points of the current socket. The same action must be executed for the rest of the measurements that the device has available within its functions.
measures intensities
This step can be more complex. First, it is necessary to set the multimeter to intensities with the rotating wheel. Next, the circuit must be opened to locate the terminal of the red cable and that the current passes through the tester.
Disconnect the resistor
Disconnect the electrical power supply going to the circuit. Remove the solders to be able to insert the probes of the multimeter cables.
Select the type of current and connect the probes
On the multimeter, set the type of current to be tested whether it is alternating current or direct current. Next, it is necessary to connect the black probe to the COM input of the multimeter, while the red cable must be connected to the input of the multimeter called amps. Then, it is necessary to connect the other side of the cable in the circuit so that the current can flow and enter the multimeter in order to return the data. In order for the energy to come into contact with the cables and pass to the multimeter, it is necessary to reactivate the circuit.
read the measurement
On the device screen you will see some values that correspond to the measurement that has just been made. Write down these data and remember to consider the unit of measurement.
Be careful
When working with electricity it is necessary to be careful and pay attention to the type of measurement that is carried out. Avoid connecting test leads to current inputs and making a voltage measurement. This can cause a short, as well as damage to the circuit being measured, the meter, and the user.
What can you measure in your car with a multimeter?
The multimeter is a versatile tool, with which to carry out all kinds of electrical measurements. Something that is quite useful in our vehicle, as an aid when looking for faults or breakdowns in its components.
Although a car is essentially a mechanical vehicle, the truth is that it also has a fundamental electronic part. From the starter to power windows to a host of car accessories, they all depend on electricity. All this without forgetting the battery, which is responsible for storing all the vehicle’s energy, which is obtained through the alternator.
All these systems require some control and periodic verifications, in which having the best multimeter can be of great help. It is true that we are not talking about something that is within the reach of all users, but they are easy measurements to carry out if we have the right tool and knowledge. So that you have an idea of the usefulness of this product, we leave you some of the most frequent uses that it has in the car.
battery voltage
Traditionally, the use of the multimeter to measure the battery voltage has been the most common that has been given to a device. Something that allows estimating the state of charge of the battery and its capacity, being useful to assess if it is really necessary to change said battery or if we can keep it longer.
The measurement process is as simple as placing the test rods on the battery terminals, starting with the black rod, which is placed on the negative terminal. The red cable, for its part, will be placed on the positive terminal. At the moment, we will have the measurement on the screen. If this measurement shows values greater than 12.5 volts of charge, then the battery is in good health. But if the battery is below 12.2 volts, then you will have to charge it and even think about replacing it.
Ignition System Check
All the systems that manage the ignition require electrical current to function. From the spark plug to the ignition coil, without forgetting the corresponding voltage regulators.
All these elements can also be verified with a multimeter, in order to assess whether they meet the expected parameters within normal vehicle operation. As a reference, in the case of the ignition coil we can measure the electrical resistance offered at the time of ignition, which can vary from 0.3 to 1 ohm for electronic ignition coils, increasing that range to 3 to 5 ohms for ignitions with breaker.
Regarding the spark plugs, this element allows to measure the intensity of the electrical charge that they develop when igniting the mixture of air and fuel. In the event of a spark plug failure, it is always a good idea to verify that the electrical wiring is carrying the energy correctly, in addition to checking that the state of the spark plug itself is adequate. However, in case of failure, this is an economic problem to solve.
As for the regulator, the multimeter allows us to verify that it is adequately fulfilling its mission, so that we do not perceive large voltage variations in the system when the vehicle is switched on or when it is operating. In both cases, it is advisable to carry out measurements on the input and output elements of this regulator, to check that the voltage varie
