Despite the seemingly lengthy list, you may rapidly verify these issues using the multimeter. As a result, we will talk about how to inspect the Board for electrical faults using thedigitalmultimeter. Let’s think about numerous approaches of testing and how tocheck circuit boardcomponents. Reques...
The same confidence is reflected during times when I need to test a circuit board. While there’s no steering wheel involved, I have other tools that help in identifying faults in the circuit. It can be a struggle but when you have a systematic test procedure you’re bound to locate the...
变频器的主电路如何上电检修(How to check the main circuit of power converter) How to check the main circuit of power converter for electrical work? The inverter maintenance personnel must set up the idea that the inverter module and the drive circuit have a strong joint on the fault. When ...
1、硬盘故障怎么检查(how to check the hard disk fault)how to check the hard disk faulttag: hard disk bad sectorsin the brain hardware equipment failure occurs, the proportion of hard disk failure is still relatively high. because the hard disk occupies a very special position in the brain ...
2. if it is manual welding, it is necessary to develop good habits: A. Visually inspect thePCB board before soldering, and use a multimeter to check whether the important circuit (especially the power supply and ground) is short-circuited or not; ...
to BDs. Therefore, before switching from a stack to an M-LAG, check whether the total number of VNI-bound BDs and Layer 2 sub-interfaces on the device exceeds the maximum number of Layer 2 sub-interfaces supported by the device. For details about specifications, visithttps:/...
If you’re feeling adventurous and have a device’s wattage and amperage, you can alsocalculate the ohmsby combining the Power Formula and Ohm’s Law. Confused yet? Don’t worry about it. Unless you’re building and testing electronics or looking for faults in electrical circuits using anohm...
Reason One: Green PCB Is More Conducive to the Detection Visual inspection is crucial in the circuit board manufacturing process. Although a kind of optical appearance inspection machine called AOI is commonly used now, the final check is done by a well-trained inspector with direct visual observa...
For example, you can inspect the diodes and transistors with the diode settings in the multimeter. The base-collector and base-emitter junctions act as diodes. If it’s a simple board design, you can check all the connections for open and short circuits. Just set the meter to ohms or the...
The device provides a small number of ACL resources in the egress direction. Therefore, you need to pay special attention to these ACL resources. The following uses the CE12800 as an example. Run thedisplay system tcam service briefcommand to check the ID of groups and number of rules used ...
