multimeter may seem complicated and intimidating at first glance, but it is extremely simple to use.For voltage measurements need to install the counter provided for the high range VAC.The highest possible range is selected so that the device was not damaged by stress more than expected.
If the counter has been set to the range of 50 volts and you want to check electrical outlet, 120 volt electrical outlet may cause irreparable damage to the multimeter.It is better to start with a high range and work down to the low range that can be safely mapped device.If you're doing it for the first time and did not know how to test the circuit multimeter, then just follow the instructions.
Insert the black test lead to "COM" or "-" in the socket.Insert the red test lead into the "V" or "+" in the socket.Find the magnitude of the voltage.There may be several volts values with different maximum values.Selected range switch
Check all electrical outlet.In Russia, you can expect 120 volts or 240 volts.In some places, 240 or 380 volts also possible.Using the method of how to ring circuit multimeter, be careful when working with the instrument.Click on the black test lead to one of the outlet openings.You must use the black lead, as usually insert the plug into the socket.
Insert the red probe into another hole outlet.The instrument should display the voltage is very close to 120 or 240 volts (depending on the type of scanned output).Remove the sensor, and turn the knob to the lowest offered volt range, it is more than the specified voltage (120 or 240).
This method is to ring circuit requires care when working.Insert the sensors again, as described above.The device may indicate between 110 and 125 volts at this time.The range of the meter is important to get a precise measurement.
If the cursor does not move, it is likely that DC was chosen instead of AC.AC and DC modes are not compatible.the correct mode must be set.If it is not installed correctly, the user will mistakenly believe that there is no tension.It can be deadly.Be sure to try both modes, if the pointer does not move.Set the meter to AC power mode and try again.
