How to check the battery multimeter: that allows to measure the meter

There are many types of AA batteries. Outwardly, they practically do not differ from each other, but they are in their largely technical parameters are different. Over time, these batteries begin to lose their charge - it means that from time to time there is a need to check them. This can be done with a special device - a multimeter. It is truly versatile and can replace several instruments.

battery types and their characteristics

Batteries come in several forms. First of all, it is a disposable galvanic cell. Use it for as long as it is not fully discharged. Then disposed of and replaced with a new one. They can not be recharged, but our craftsmen sometimes neglect this rule, trying to extend the life of batteries. But only rarely manage to fill it charge for at least 15 percent. In other situations, it may simply explode.

In turn, disposable batteries are alkaline and saline. The latter have a longer service life. However, their cost may be higher by 1.5-2 times.

batteries also exist. They can be recharged several times. To this element include lithium type batteries for gadgets, and alkaline batteries. They are characterized by tension and, of course, cost.

Which allows to measure the meter

Even the most simple multimeter is a versatile instrument for measuring various parameters in electrical appliances. It allows you to determine the voltage, current, resistance, and even conduct a routine check of the wires to break. Also it can be used to check the batteries in the fitness and see the condition of the electronic circuit.

Multimeter combines all the functions of a voltmeter, ammeter and ohmmeter. On sale you can find two kinds: analog and digital. Each has its pros and cons. Let's take a closer look at each of them.

Analog multimeter is equipped with an arrow to the scale on which can be observed and measured results. In some instruments (specifically, on cheap Chinese product) scale realized not the most convenient way, and the beginner is sometimes difficult to understand in such a device. However, they are very popular, as the cost of such products is not more than a couple of dollars.

The downside analog multimeter measurement error is small. To obtain higher accuracy, it is necessary to set up trimmer. However, if you want to get more accurate data, it is best to take advantage of digital multimeter.

The main difference is that the measurement results are shown on the display. Such devices have higher accuracy and are easy to use because it is not necessary to understand all the nuances of a graduated scale.

The device itself has two outputs, which are connected to the wires (red - plus, and black - weight). Nests themselves are signed, so they are difficult to confuse. If you want to make Multimeter worked in ohmmeter mode, it is enough to put the selector knob to the desired position.

How to check the penlight batteries Multimeter

To check penlight batteries must use a digital multimeter, since he will show more accurate results. To properly conduct an audit, feelers device must be installed in their nests. Now you need to set the switch to a value of 20. Then take the red test lead and connect it to the "plus" batteries. Then to the "minus" attach black probe.

The device will power, and there is nothing wrong if the figure was highlighted in the display, for example, 1.45. This item is suitable for work, even though he does not show the maximum voltage. Just had low amperage or in case there is minor damage.

It is worth noting that if the battery is under load, then it can also be checked. To do this, you need to attach it to any electrical device, and to make contacts multimeter probes.

Reference. As an experiment, you can take even the simplest motor in the 3 (they put many toys, so this option is best). During voltage drop can occur procedure. This is due to the fact that the motor works hard and takes the energy of the battery.

Check mizinchikovoy batteries

In general, the most significant differences is simply no test procedure. The only thing that mizinchikovoy size batteries a little less so, to measure its performance will be a little more difficult.

checking algorithm is as follows:

• connect probes to the measuring device;
• the lever on the numerical value "20";
• Connect the red test lead to the "plus" batteries;
• attach the black test lead to the "minus".

Important! If you are using a stylus instead of conventional wires, for convenience they can be stuck with tape or duct tape.

How to check other types of batteries

Verifying other types of batteries will not be materially different from the procedure described in the preceding two paragraphs.

If you want to check the phone battery or other mobile device, simply attach the probes corresponding to the color "plus" and "minus" terminal on the battery. If the marking on the element is missing, it can be determined independently.

Important! Typically, mobile phone battery voltage is 3.7 volts. If this value is higher, then most likely the battery is simply outdated, and perhaps somewhere a bit swollen.

Another plus analog multimeter is that it allows you to check even the battery from the wrist watches, which is characterized by its small size. To do this, you need to lean against the black test lead to the top of the "pill", and the red to the side, because this element plus power covers almost the entire area of ​​the batteries.
