1, may be the mobile phone protective shell is too thick wireless charging short circuit test , it is recommended to choose when using wireless chargingChoose a thin phone case or don't use it. It may be that the phone is not aligned with the charging area of the wireless charger, it is recommended to check the wireless charger specification to determine the wireless charging area. It may be that the wireless charger is not suitable for the wireless charging system of the mobile phone, so it is recommended to use the charger that meets the wireless charging requirements of the mobile phone.
2, Apple 12 wireless charging can not be used for the following reasons wireless charging short circuit test : The purchase and use of wireless charger is not compatible. A charger that supports the Qi wireless charging standard is required for wireless charging. Make sure the charger is working properly, andMeets the wireless charging requirements of the Apple 12. There is a physical barrier between the wireless charger and the iPhone 12.
3, Apple 15 wireless charging may not be charged for the following reasons wireless charging short circuit test : The device is not aligned with the charger. If the device is not properly placed in the center of the charger, or there is a physical barrier, it may cause charging failure. The charger is not connected to power. Make sure the wireless charger is plugged into the power adapter and connected to the power supply. The power adapter is faulty. If the power adapter is faulty, it may affect noneIf your mobile phone cannot use wireless charging, please follow the following steps: Check whether the mobile phone is overheating. It is recommended to charge it in a good heat dissipation environment. Check whether the wireless charger indicator light is on normally, and check whether the connection between the charging base, data cable, charger, and power supply is in poor contact. It is recommended to reinsert the wireless charger.
3, different brands of models due to the difference in coil position, may lead to low charging efficiency or can not be charged, please put the mobile phone wireless charging area correctly in the wireless charger induction area to try. Please do not use too thick or magnetic insulation material/metal case, these cases mayCan affect the charging efficiency or can not be charged, and even overheating causes the phone to be unable to charge or damage.
4. Please use other receiving devices that support wireless charging (such as Mate20 pro, iPhoneX, iPhone8/P30 Pro) to try wireless reverse charging. If it can be charged, there may be a problem with the receiving device. Please check whether the mobile version is the latest version: Click Settings, enter software Update in the search box, and click Check for Updates.
5, replace the wireless charger: when our mobile phone appears such a situationWhen the situation, it is likely that we have a problem with the charger, at this time we can replace a wireless charger to try (original wireless charger or usb data cable) to restore factory Settings: if the fault is still on after the boot, at this time we can restore the phone to factory Settings to try.
6, if the charger used is not compatible, it may also lead to wireless charging. Device overheating: If the temperature of the phone is too high, it may cause the wireless charging function to fail. Please put the phone in a cool and ventilated place, and try wireless charging after the phone temperature drops. Battery damage: If the phone battery has aged and damagedWireless charging may not be possible. You can go to a professional repair center to replace the battery and try wireless charging again.
If your detector does not turn green, it may be that the power supply is not properly connected or out of power. Check the power indicator to ensure that the power is properly connected. Safety test When opening the cover test, remember to depress the anti-demolition switch. Check that the power light is on to ensure that the detector is safe and reliable. Troubleshooting If the detector alarms, the red light is flashing but no signal is transmittedOut, maybe the motherboard plug-in or the eight-pin plug fell off. Check the plugins and plugs to make sure they are connected properly.
An abnormal increase in the current in the line may indicate a short circuit or ground fault. The fault indicator can immediately alarm when the current exceeds the preset threshold, so that you can detect the hidden trouble in advance. This article will introduce the working principle and characteristics of the two fault indicators to help you choose the right product. Overcurrent principle The fault indicator based on the overcurrent principle can accurately monitor short circuits and ground faults. It immediately alarms when the current exceeds the preset threshold, so that you can find hidden dangers in advance.
This article will focus on the introductionThese two provisions help readers better understand the design and implementation of grounding systems. In an effective grounding system, the grounding conductors (wires) of electrical installations in power plants and substations must undergo rigorous thermal stability checks to ensure safe operation under the current of a grounding fault (short circuit).
First turn off the power supply, use the resistance of the multimeter to measure the on-off of the line, such as zero resistance, that is, short circuit; If the resistance is infinite, the circuit is broken. Then send the power supply, use the voltage file of the multimeter to measure the voltage of the electrical appliance, if there is 220V, it is normal; Re-measure the metal casing of the electrical appliance against the groundThere is no voltage between the lines, if there is leakage. Short circuit, its resistance is basically zero, with a multimeter resistance can be measured. Disconnect the circuit when measuring.
Its control unit Micrologic is the key to setting these protection parameters. On the Micrologic control panel, numbers and letters identify protection types and functions. For example, the number 2 represents basic protection, including long delay and instantaneous; 5 indicates selective protection, including long delay, short delay and instantaneous; 6 and 7 add ground fault or leakage protection to provide more comprehensive protection.
1, wide impedance range, to meet a variety of needs the inductance of the wireless charging coil is usually at the micro hen level, the test frequency is in the kHz range, which requires a wide and accurate measurement range. The E4980A/AL has a wide impedance range from 4 milliohm to 100 milliohm, and can cover this band with 10% accuracy, making it particularly suitable for the precise evaluation of wireless charging coils.
2, the secondary winding is broken, the wireless charging coil has two windings, one is the main winding, one is the secondary winding, after the secondary winding is damaged, it will causeThe main winding heats up and the output has no voltage.
3, wireless charging coil test coil capacitance to the ground because the capacitor is the electric field energy and magnetic field energy conversion material, in the process of wireless charging, electric field energy and magnetic field energy need to be converted. The process of wireless charging is the transmission of electric energy from the charging device to the receiving device.
4, plug the wireless charger into the power supply, and check whether the wireless charger is working properly. If the wireless charger does not work properly, you can try to replace the charger or check whether the cable of the charger is damaged. Place your iPhone on a wireless charger and watchWhether the phone starts charging. If the phone does not start charging, you can try adjusting the position of the phone or repositioning the phone. Check whether wireless charging is enabled on your phone.
