Użu ta ' il multimeter 's live wajer rikonoxximent funzjoni

Electricians used to use electric pens for maintenance and troubleshooting, but now they use a multimeter. In fact, not only can electric pens distinguish between live and zero wires, but a multimeter can also distinguish between live and zero wires, but a multimeter can also distinguish between live and zero wires, li is just unknown to many people

Il-Metodu ta' Tiddistingwi Live Line u Zero Line with Electric Pen

Ordinarju elettriku pinna: In the past, for electricians to repair and troubleshoot, it was just one electric pen li went global. Ordinary electric pens distinguish between live wire and zero wire, and most people basically know that using an electric pen to directly measure the live wire and zero wire, the light system and the light off the electric pen is the żero wajer

Digital electric pen: Since the advent of digital electric pens, ordinary electric pens have been rarely used. For digital electric pens, there are many functions, such checking for broken wires when not charged, distinguishing between zero and live wires, distinguishing between zero and live wires, distinguishing between the positive and negative poles of DC batteries, and determining jekk wires are short circuited. Therefore, ordinary electric pens have gradwalment issir skadut. Jekk digital electric pens are used to distinguish between live and zero wires, they can directly measure the live and zero wires with an electric pen and observe the voltage of the digital electric pen, pen, If the massimu voltaġġ voltaġġ displayed is 220V, it proves to be a live wire. If the maximum voltage displayed is 12V or 36V, it proves to be a zero wire

Inductive breakpoint measuring pen: The main function of a breakpoint pen is to locate the internal breakpoint of the circuit after the wire is not powered on. The breakpoint pen distinguishes between the live wire and the zero wire, and uses the breakpoint pen to measure the live wire and the breakpoint pen to measure the live wire and the zero wire separately. When measuring the live wire, the sound emitted by the breakpoint pen is relatively rapid, filwaqt li meta kejl il żero wajer, il ħoss emitted huwa relattivament bil-mod

Method for distinguishing between live and zero lines with a multimeter

Għal a multimeter, there is an AC voltage range. For an AC voltage range, the voltage of the AC power can be measured. When measuring the voltage, a red and black probe is used, placed on the live and zero lines rispettivament, to display its voltage. However, when measuring the voltage, it should placed placed in the appropriate range. For example, when measuring household 220V and 380V vultaġġi, il multimeter għandu ikun imqiegħed fi il ac vultaġġ firxa ta ' 700V

For AC voltage levels, not only can voltage be measured, but it can also distinguish between live and zero lines. It's just that many people don't know. A multimeter distinguishes between a live wire and a zero wire. Place the multimeter in the AC voltage range, place the black probe aside, and use the red probe to measure the live wire and zero wire separately. Osserva in-numri fuq il multimetru, u dawn ma the the larger numbers are the the larger numbers are the live wire and the ones with the smaller numbers are the zero wire. If you feel that the numbers are not very obvious, you can adjust the range to a smaller one, so that the numbers will be more obvious

For the AC voltage range of a multimeter, not only can it measure voltage and distinguish between live and zero wires, but it can also find internal breakpoints in the wires
