2. When troubleshooting a paperless recorder in a wet environment, it is necessary to measure whether the various points on the printed circuit are unobstructed, because the main fault in this case is corrosion of the copper foil.
3, with a multimeter ohm block, remember not to live measurement.
4. 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.
5. When inspecting the internal circuit of the paperless recorder, if the contacts and circuit boards of the mounting components are coated with insulating varnish, the common parameters of the parameters can be measured by using ordinary hand-stitched needles on the test leads of the multimeter so that the paint layers can be directly measured. Point, without peeling off the paint layer.
6. Do not hot plug various control boards and plugs. In the case of power-up, the plug-in control board will generate a strong induced electromotive force. At this moment, the instantaneous counter-attack voltage is very high, and it is easy to damage the corresponding control board and plug.
7. When using logic pens and oscilloscopes to detect signals, be careful not to make the probes contact two measurement pins at the same time to form a short circuit.
