What should pay attention to maintenance push-pull timing, many users who purchased the push-pull gauge will encounter damage repair, but after each repair will not be too long there will be other places damaged, which is why, in fact, this is It was during maintenance that we did not pay attention to the small details of some repairs. Therefore, Heng Gang's push-pull force gauge Xiao Bian tells customers to pay attention to what maintenance push-pull timing. What should pay attention to maintenance push-pull timing: 1. When using the logic pen and the oscilloscope to detect the signal, be careful not to make the probe contact the two measuring pins at the same time because the essence of this situation is to form a short circuit under power-on condition. 2. When using a multimeter to ohmically block, remember not to take live measurements. 3. When repairing precision instruments and meters, if you inadvertently fly a small part, you should first determine where it might fly, and do not look east or west. You can use magnetic scanning and line-of-sight scanning methods to find out. 4. When the internal circuit of the instrument is repaired, if the contacts and the circuit board of the mounting component are coated with insulating varnish, an ordinary hand-stitch can be used to weld the surface of the multimeter to measure the parameters. There is no need to peel off the paint layer. 5. Do not blindly knock on and off when overhauling, so as not to expand the fault, the more repaired the worse. 6. When troubleshooting a meter in a wet environment, it is necessary to test whether the various points on the printed circuit are unobstructed, because the main fault in this case is corrosion of the copper foil. 7. Do not hot plug various control boards and plugs. Because in the case of power-up, the plug-in control board will generate a strong induced electromotive force, then instantaneous counterattack voltage is very high, it is easy to damage the corresponding control board and plug. 8. When disassembling and adjusting the instrument, record the original position for recovery. 9. 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 short-circuit line should not be used to discharge the capacitor instead of the lead wire, because it is easy to blow the core wire. It is possible to take a 220V, 60 to 100W lamp with a cap lead, which is connected to both ends of the capacitor. The lamp will flash at the moment of discharge.
