How to use DY15 wireless voltage tester

When using a voltage tester, you can directly put one end and then point it into the circuit to measure.

The new voltage tester is a hard rock tool product, which is suitable for direct detection of AC and DC voltages of 12V and 250V, and indirect detection of neutral wires, phase wires and break points of AC current, and can also measure the on/off of uncharged conductors. Intuitive readings, full of features, and cheap.

This kind of voltage tester can be used, first of all, you have to see if there is electricity in the battery, if there is electricity, you can directly plug this car shop into the power supply to display.

The test pen is also called the voltage tester, referred to as the "electric pen". It is an electrician's tool used to test whether there is electricity in a wire. There is a neon bubble in the pen body, if the neon bubble glows during the test, it means that the wire is electrified, or it is the live wire of the path.

The nib and tail of the pen are made of metal materials, and the barrel is made of insulating materials. When using the tester, be sure to touch the metal part at the end of the tester with your hands, otherwise, because the charged body, the tester, the human body and the earth do not form a loop, the neon bubble in the tester will not glow, resulting in misjudgment

The voltage tester forms a circuit through the human body to the ground, so the voltage tester needs to touch the metal part of the watch pen with your hands. The electric pen measures the zero line, and the light of the electric pen does not turn on.

This radio cake is very easy to use, you put that um one finger on top of the electric pen, put that electric pen in the socket and you can try it.

When the voltage tester is in use, you can connect one end to the circuit and use it directly.

DIY wireless how to use this workshop ratio, this is still relatively simple, he asked the second question of this voltage tester, then there is a finale at the top of it directly pressed down for him, and it can be measured later.

This way of using it is very simple, you can use it directly after powering it up.

This kind of battery needs to put the motor on the wire, and then it can sense whether there is electricity or not.

Well, this is generally a case of measuring some current, and you can see it in a specific manual.

This wireless voltage tester must be noted, it can be used to measure the live wire remotely.

In this case, you can take a look at one of its related instructions, or some use of the situation to solve the problem.

How to use a wireless detection pen in Dubai, you can refer to the manual to use it, it's very simple.

The method of using the electric tester is: one-handed operation, clamp the back half of the pen barrel with the index finger and the middle rotten skin smiley finger, and press the metal part of the tail of the electric pen with the thumb, so that the current of the charged body to be measured is introduced to the earth through the pen tip, 5 trillion current limiting resistance, neon bubble, spring, pen tail, and the human body to form a loop, and the neon bubble can shine normally. In addition, people wear insulated shoes or stand on a wooden bench to measure the charged body, and the electric pen can also correctly display the charged, which is the distributed capacitance between the human body and the ground to provide an AC path (the two conductors are close to each other and insulated from each other, forming a capacitor).

Touch the metal at the end of the tester with your hand and measure it directly.

One end is connected to the positive electrode, and the other end is connected to the negative electrode.

A friend's power socket ignited due to loose screws, resulting in poor contact. So, he pulled down the gate knife on his line, and confirmed that the lights that had just been on were turned off at the same time, and prepared to overhaul himself. But when he opened the socket cover and tested it with a voltage tester, he couldn't help but be shocked.

The neon tube of the voltage tester is bright, and the socket is obviously live (it was later found that it was caused by sharing the zero line with a neighbor). Fortunately, he prepared a test pen, and he had an extra eye before the test, otherwise the consequences would be unimaginable.

In our daily lives, we often encounter electric shock accidents caused by leakage of household appliances and live metal conductors being mistaken for no electricity. In fact, if you have a voltage tester at home, use a voltage tester to measure the relevant conductors when checking the leakage of household appliances or repairing electrical circuits, and how to use it to identify whether it is electrified, and some electric shock accidents can be completely avoided. Moreover, a voltage tester is only a few yuan, and under normal circumstances, a little consultation with an electrician will quickly grasp the essentials of safe use.

Therefore, it is recommended that every family should have a voltage tester, especially with the increasing household electricity consumption and the increasing popularity of household appliances, it is more prepared to prepare a voltage tester.

Before testing whether the electrical appliances and circuits are electrified, you should try it in a place where there is electricity to see if the voltage tester is in good condition to prevent electric shock due to misjudgment.

When holding the pen, press and hold the tail of the voltage tester with your fingers, and hold the pen with the rest of your fingers.

When measuring electricity, the tip of the pen touches the test body, and the hand touches the tail of the tester. If the test body is electrified, the neon tube of the voltage tester will glow; If the neon tube does not emit light, the test body is not charged.

Voltage testers with an insulation resistance of less than 1 trillion ohms cannot be used.

When using an electric pen, the neon tube window should be backlit so that it can clearly see the red light emitted when it detects the charge of the charged body.

After the pen is held, generally touch the top metal with the thumb and index finger, touch the test point with the tip of the pen, and observe whether the neon tube is glowing at the same time.

If the neon tube of the electric pen emits a weak light, it must not be concluded that the voltage of the charged body is not high enough, perhaps there is dirt at the test point of the electric pen or the charged body.

It is also possible to test the ground wire of the charged body, in which case it is necessary to wipe the electric pen or re-select the test point, and after repeated testing, it can be determined whether the test body is charged or not.

Proper use of the electric pen:

Place your index finger against the cap end of the pen, gently pinch the pen with your thumb, middle finger, and ring finger to keep it stable, and then insert the metal nib into the socket panel hole on the wall, or into the socket hole of the external power strip.

To judge whether it is charged, it is necessary to check whether the neon tube in the middle of the voltage tester is glowing, and the one that emits light is charged. If the light is not obvious during the day or in a place where the light is strong, you can block the light with your hand and observe carefully.

Before using the tester, first check whether there is a safety resistance in the tester, and then intuitively check whether the tester is damaged, whether it is damp or watery, and can only be used after passing the inspection.

When using the tester, do not touch the reed branch with your hand to touch the metal probe on the front end of the tester, which may cause an electric shock accident.

When using the tester, you should touch the metal part at the end of the tester with your hand, otherwise, because the charged body, the tester, the human body and the earth do not form a loop, the neon bubble in the tester will not emit light, resulting in misjudgment, thinking that the charged body is not charged, which is also very dangerous.

The tip of the home electric pen is in contact with the wire, and the rear end of the electric pen is pressed with the thumb, and if the light is on, it proves that there is electricity.

1. Physical electric pen: The index finger is against the cap end of the electric pen, and the thumb, middle and middle split finger and ring finger are gently pinched to keep the electric pen stable.

2. The neon tube in the middle of the electric pen is charged if it is luminous, and it is not charged if it does not shine.

3. Digital display voltage tester: the object tests whether there is electricity inside or inside the wire with insulated skin.

4. The electric tester with Weisen display lightning symbol indicates that it is electrified, otherwise it is not electrified.

How to use:

1. Determine AC and DC formula: The electric pen determines AC and DC, AC is bright and DC is dark, AC neon tube is bright throughout, and DC neon tube is bright at one end.

Before using a low-voltage electric detector, it must be tested on a confirmed live body; Do not use the electric tester until it has been confirmed that it is normal. When distinguishing between AC and DC, it is best to make a comparison between the "two currents", so that it is obvious. When measuring alternating current, both ends of the neon tube shine at the same time, and when measuring direct current, only one end of the neon tube is extremely bright.

2. Determine the positive and negative electrodes of direct current: the electric pen determines the positive and negative electrodes, and the neon tube should be carefully observed, the front end is bright and the negative electrode, and the rear end is bright and positive.

The front end of the neon tube refers to the end of the tip of the electric pen, the back end of the neon tube refers to the end of the hand, and the front end is bright as the negative pole, and vice versa. During the test, it is necessary to pay attention to: the power supply voltage is 110V and above; If people and the earth are insulated, one hand touches either pole of the power supply, the other hand holds the voltage tester, the metal head of the electric pen touches the other pole of the tested power supply, the front pole of the neon tube is shiny, and the power supply touched by the measurement is the negative pole;

If the rear pole of the neon tube is shiny, the power supply of the measured touch is the positive pole, which is based on the principle of DC unidirectional flow and electron flow from the negative electrode to the positive electrode.

3. The difference formula for determining whether the DC power supply is grounded and the positive and negative electrode grounding: the DC coefficient of the substation, the electric pen does not shine when touched; If the light is close to the tip of the pen, there is a ground fault at the positive pole; If the light is close to the end of the finger, the ground fault is at the negative pole.

The DC coefficient of the power plant and the substation is insulated from the ground, and the person stands on the ground and touches the positive or negative electrode with the electric detector, and the neon tube should not be shiny, if it is shiny, it means that the DC system has a grounding phenomenon; If the glow is at one end close to the nib, the positive electrode is grounded; If the light is at one end close to the finger, the negative electrode is grounded.

4. Determine the same phase and different phases formula: determine that the two lines are the same and different, each hand holds a pen, the two feet are insulated from the ground, the two pens each touch a line, and the eye ** a pen, not bright and the same phase is different.

When doing this test, remember that your feet and the ground must be insulated. Because most of our country is 380 220V power supply, and transformers generally use neutral point direct grounding, so when doing the test, the human body and the earth must be insulated to avoid forming a loop, so as to avoid misjudgment; During the test, two light and non-light displays are the same, so only one can be seen.

5. Determine the 380 220V three-phase three-wire power supply line phase wire grounding fault formula: star connection three-phase wire, the electric pen touches two bright, the remaining one is weak, and the phase wire has been grounded; If there is almost no light, the metal ground is faulty.

How to use:

When testing the charged body, the staff should let the metal probe of the electric detector touch the charged body, and at the same time touch the metal piece at the end of the electric detector with their hands, if the charged body has a current through and makes the circuit unobstructed, the neon bubble of the electric detector glows.

The following points should be paid attention to when using a voltage tester:

1) Before using the electric tester, the electric tester should first be calibrated to ensure that the function of the electric tester is normal. We can test on a known power source to check if the neon bubble emits light. We also need to check whether the electric detector is damp or watery to ensure our own safety.

2) Before using a voltage tester to enter the electric field test, check whether the voltage in the place is applicable. Do not attempt to test voltages higher than the applicable range with a voltage tester to avoid danger.

3) When using the electric detector, do not touch the metal probe at the front end of the electric detector with your hands to avoid electric shock accidents; When using a voltage detector, be sure to touch the metal piece or metal hook at the end of the voltage detector with your hand. If this is not done, although the neon bubble of the electric detector does not emit light, because the charged body, the electric detector, the human body and the earth do not form a circuit, it is impossible to correctly judge whether the charged body is charged or not, and it will be very dangerous if it is misjudged.

4) When using the electric tester in bright light, special attention should be paid to judging whether the neon bubble of the electric tester is really shiny, many accidents are caused by careless misjudgment, we must avoid this.

1.No, the human body is a conductor.

2.It is because it has requirements for the electromagnetic field to be induced, and the electromagnetic field must be strong to be induced.

3.No, this kind of electric pen display is only an induction, and the judgment of the electromagnetic field cannot be defined by the numbers above, but only the approximate reference value.

1.Yes 2Induction is a device that measures electrical equipment... You measure the power of your home's electrical appliances, such as refrigerators and the like, if the grounding is intact, then there may be no induction.

3. Yes, as long as your hand touches the other end of the voltage tester, it is the voltage to the ground.
