Current measurement multimeter alone

How to measure current multimeter?

First you need to understand how this device.Let's start with the symbols on the multimeter.On any device always has:

1. resistance icon.It shows the mark, which you need to put the pointer.It also specified resistance range.Typically, it ranges from 0 ohms to 200 megohms.
2. DC.It indicates where to place the switch.Approximate measuring range: 0 - 1 kA.
3. similar icon for the AC.Measurement range - 0 - 750 A.
4. icon measure DC and AC voltage.I measure the voltage in the range 20V
5. icon diode continuity.Its peculiarity is that when the resistance value of 100 Ohm Multimeter comes the peak signal.

Responding to a question, how to measure the force of the current multimeter, it must be said that while the test leads are connected in series with the load.Thereafter, the handle is placed on the corresponding icon, in this case, a constant current.

For example, the load is the fan from the computer.Then the one who wants to know how to measure the force of the current multimeter should put on the screen 12 and twist the knob of DC.The instrument will exhibit a limit current measurements up to 20 A.

First you need to check the unit for a certain device, the current in which is known in advance.For those who already know how to measure the current power multimeter, it will be very easy to do this.

Usually, those who know how to measure AC multimeter, connect the device to one of the phase conductors breaks device.When the current frequency measurement is worth considering that if the current is 200 mA, and a special terminal, the probe must be moved for him.

As multimeter measures the resistance?

a part of any multi-function multimeter always have an ohmmeter.With his help and the resistance measurement is performed.With this device it is possible to easily know the resistance network, circuit or resistor.In addition, measurement of resistance allows you to check the serviceability of many elements of the power grid -. Resistors, transformers, fuses, inductors, etc. With the help of a multimeter resistance measurement, you can also check the performance of the capacitors, transistors detect breakages transitions, to determine the integrity of the electrical connections.

Responding to a question, how to measure the resistance of the resistor multimeter, you first need to select the section labeled omega icon.If you do not know how to measure the resistance of the network, start with an exemplary determination of its size in the measured network.Exposing the limit of measurement, make sure that it was more than the expected resistance of the resistor.

Knowing how to check the resistance of the multimeter, you can easily avoid many failures of network elements.When measured can not be touched by hand probes and other live parts of the device, as this device is to measure the resistance of your body, which means that the result will be incorrect.The video shows in detail the measurement process.

Ability to work with this device it is important for those who want to learn how to measure the resistance of the multimeter to the ground.Knowing the grounding resistance can easily avoid many of the difficulties in the work.
