What is Multitester?
Multitester or multimeter is a device that can be used to collect electrical circuit data. The basic multitester can measure resistance, voltage and continuity, while more advanced versions can be able to provide additional data. This tool can be very useful for having around the house and anyone who plans to perform electrical repairs should definitely use a multitester for safety reasons. In most cases, Multitesters can be used with a current off or on, although the use of a device with a power current can sometimes lead to damage to the device.
This device is manually held and powered by batteries. It consists of two probes connected to a central package that can be digital or analogue. The device has a number of buttons or switches that can be used to set the measurement type. A rubber case can be used to facilitate the multimeter handling. For a continuity test, the device is set to "Ohms" and AC or DC, depending on the current measured thanWith the probes on the device inserts into the circuit. If the perimeter is completed, it is evaluated between 0 and 0.05 Ohms. Measurement of infinity suggests that the perimeter is open, which means there is a problem.
In addition to being used as a basic continuity tester, a multimeter can also be used to test ground failure, which is a very dangerous electrical problem. To use a ground failure, the "OHMS" settings should be selected before inserting one probe into the terminal and the other is located on the perimeter cover. Reading should be infinity, suggesting that the perimeter is open. Furthermore, the probe should be moved to the second terminal and returned further reading infinity.
The use of a multimeter can help narrow the ELECHECHLE CTRICALLY and test the repairs of the electrical system. Multimeters usually come up with instructions providing information about all measurements that can make a device and indicate whether performance wouldwas to be turned off or on before performing the tests. As always, it is good to know where the circuit breakers or fuses for the house are, so in an emergency you can quickly turn off the energy.
