Before we use electronic scales, we must first do a check on it, that is, power inspection. This step is very important. If it is not checked, it may lead to problems in the use of electronic scales, such as electronic scales. The weight is not accurate, so we must check it before use. Then the following Xiao Bian came to tell everyone about the electronic scales check before power it, I hope everyone can learn more about electronic scales information through this article.

Before the power is electronically scaled, check:
Check before power up. Do not rush to power-up checks when servicing electronic equipment. The failure of electronic pounds is mainly caused by the damage of circuit components such as resistors, inductors, and capacitors, and electronic components such as electron tubes, transistors, and integrated circuits, as well as transformers, meters, and switches. It may also be due to circuit or mechanical connection. Line or contact caused by poor contact.
Among them, signs such as resistor burnout, capacitor leaking or bursting, leaking or loosening of tubes, power transformer damage, meter pinning, switch slippage, circuit disconnection, and loose couplings are easy to find. The visual inspection method is a preliminary inspection method. Observe the relevant parts and components first according to the fault phenomenon, and sometimes the fault can be found out at a glance.
In the absence of power or power, the cause of the malfunction is judged not by measurement but by the senses (hand, eyes, ears, nose). When the power supply is not turned on, first observe the presence or absence of loosening, shifting, disconnection, etc. on the switches, function keys, terminals, and fuse tubes on the panel of the electronic equipment being repaired. Open the cover of the casing, and observe with eyes whether a component of the device is discolored or moldy. Whether the component leads are peeled off, the solder joints are loose, the components touch each other, and the copper foil on the printed circuit board is And solder joints are good, whether there is corrosion, fracture, etc.; observe the internal components, components, plug-ins, circuit connections, power transformers, etc. whether there is scorch, leakage, deformation, breakdown, disconnection, poor contact and other issues . You can also dial the relevant components by hand for full inspection.
