There are many kinds of instruments and meters , and they are widely used in many fields. Because of this, in the course of instrumentation failure problems are also very much, so usually need to pay more attention to instrument repair and maintenance, can effectively improve the performance of the instrument, and can extend its life. Here is a brief introduction to the precautions for instrument maintenance and maintenance: Api Powder,Tianeptin Sodium,Medical Grade Hyaluronic Acid,Competitive Price Taurine Shaanxi YXchuang Biotechnology Co., Ltd , https://www.peptide-nootropic.com
1. When using the logic pen and oscilloscope to detect signals, be careful not to make the probe touch the two measurement pins at the same time, because the essence of this situation is to form a short circuit under power-on. When detecting the filter capacitor in the power supply , first short-circuit the positive and negative terminals of the electrolytic capacitor, and do not use the test lead wire instead of the wire to discharge the capacitor when short-circuiting.
Because it is easy to burn the core wire. You can take a 220V, 60 ~ 100W lamp with a lamp lead, connected to the two ends of the capacitor, the bulb will flash when the battery is discharged.
2. When repairing instrumentation faults in a humid environment, it is necessary to measure the smoothness of each point on the printed circuit with a multimeter.
Because the main fault in this case is copper foil corrosion.
3. When repairing the internal circuit of the instrument, if the contact points of the mounted components and the circuit board are coated with insulating varnish, the parameters of each point can be measured by ordinary hand stitching on the meter of the multimeter, so as to pierce the paint layer and directly measure each point. Instead of using a large area to peel off the paint layer, do not plug and unplug various control boards and plugs.
Because in the case of power-on, the plug-in control board will generate a strong induced electromotive force, and the instantaneous counter-attack voltage is very high, which easily damages the corresponding control board and plug.
4, when repairing the instrumentation, do not blindly knock and knock, so as not to expand the fault, the more repaired the worse.
5. When disassembling and adjusting the instrument, the original position should be recorded for recovery.
6. When repairing precision instruments and meters, if you accidentally fly a small part, you should first judge where it may fly. Do not look east, turn it over, you can use magnet scanning and line-of-sight scanning method to find.
7. In the instrument maintenance work, first understand the basic principles of instrumentation, and master the knowledge and skills related to electronics, and should prepare all the instrument manuals, drawings and other technical materials, and should develop a kind of Good work quality, so as to improve efficiency and reduce mistakes in the maintenance work of instrumentation.
The above content is the content that should be paid attention to for the maintenance and maintenance of the instrumentation introduced for everyone. I hope everyone can master these. Although there are some simple methods, the use of the user is very large.
