Check battery multimeter

How to check the battery power multimeter

To do this, follow these steps:

1. Turn on the device.We expose the switch to "DC" icon.
2. sets the maximum range.Usually it is 10 or 20 mA.
3. Now we connect the probes to the battery contacts.If you want to learn how to measure the capacity of the battery multimeter, you should remember that you need to connect minus to plus and minus to plus.
4. After that, if the pins are connected correctly, the multimeter screen battery indicator appears.Usually it ranges from 0 to 1.5.It is necessary to quickly disconnect the electrical circuit after measurement.
5. comparing the resulting value on the package, make conclusions about the future of its operation.

How to check the vehicle's battery capacity multimeter

Usually, if a car stops to wind up, the question arises, how to check the battery charge multimeter.

Responding to a question, how to measure capacitance multimeter battery, you need to carry out a final check, which is done by loading the plug.On the battery no-load is usually shown in 12-12.5 and the load - no more than 11 V.

Answering the question of how to measure capacity, some indicators need to know:

1. If the battery is fully charged, the densitythe electrolyte should be 1.24 g / cc.cu.
2. If electrolyte density decreased by 0.04 - the battery is discharged by a quarter.
3. Reduced electrolyte density n 0.08 g / cm.cube shows that the battery is half the village.

Checking the Battery Charge reduced to a multimeter measure the voltage at the terminals with no load.When fully charged battery the device will show approximately 12 6. If the reading is reduced and the meter shows 12.2 - the unit should be charged.

Means of verification

There are several ways to check a car battery multimeter.The first method is the classic - Check the battery capacity discharge control is performed.

, it is necessary to resort to the second way to check the battery capacity of the multimeter.This load must be such that it could take half the current, which is designed battery.Check if there should be a full battery charge.At the same time, connect the load as a conventional light bulb can act.If the light is dim bulbs - non-working battery.

If the multimeter showed 12.4 V, the full capacity of the battery is ready for use.

measurement of battery voltage

Typically, the terminal voltage does not exceed 24 V and observe special precautionary measures are required.To check the battery voltage or the battery, you must first measure them direct and alternating current.Measurements were carried out at the terminals, which are located at the end of the battery.To answer the question, how to check the battery voltage multimeter, you need only know the rules of the use of this device.In particular, the meter should be connected to the terminals and the switch handle on it to a pointer "AC".
