Nine precautions for overhauling instruments and meters

Abstract: The information on the nine precautions for overhauling instruments and meters is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Nine precautions for overhauling instruments: 1. When using the ohm block of the multimeter, remember not to measure with electricity. 2. When using logic pen and oscilloscope to detect signals, be careful not to make the probe touch two measurement pins at the same time, because the essence of this situation is. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following are the details of the nine precautions for instrument maintenance. Nine precautions for overhauling instruments: 1. When using the ohm block of the multimeter, remember not to measure with electricity. 2. When using a logic pen or 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 when the power is turned on. 3. When detecting the filter capacitor in the power supply, the positive and negative electrodes of the electrolytic capacitor should be short-circuited first, and the test lead wire should not be used 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 head lead and connect it to both ends of the capacitor, the bulb will flash at the moment of discharge. 4. When repairing the fault of the instrument in a humid environment, it is necessary to use a multimeter to test whether the points of the printed circuit are unobstructed, because the main fault in this case is copper foil corrosion. 5. When overhauling the internal circuit of the instrument, if insulating varnish is applied to the contacts of the installation components and the circuit board, when measuring the parameters of each point, an ordinary hand-stitched needle can be welded to the test pen of the multimeter, so as to pierce the paint layer and directly measure each point. Do not strip paint over large areas. 6. Do not plug and unplug various control boards and plugs with electricity. Because in the case of power-on, plugging and unplugging the control board will generate a strong induced electromotive force. At this time, the instantaneous counterattack voltage is very high, and it is easy to damage the corresponding control board and plug. 7. Don't blindly knock and touch during maintenance, so as not to expand the fault, and the more you repair, the worse it will be. 8. When disassembling and adjusting the instrument, the original position should be recorded for recovery. 9. When repairing precision instruments, if you accidentally bounce small parts, you should first determine the place where they may fly, do not look east, turn west, you can use magnet scanning and line-of-sight scanning methods to find. In short, in the maintenance of instruments and meters, flowmeters should first understand the basic principles of instruments and meters, and master the knowledge and skills related to electronics, and should prepare all technical information such as manuals and drawings of instruments and meters. A good work quality, thereby improving efficiency and reducing errors in instrument maintenance work. The above is the whole content of this article.
