Inspection instrument nine points for attention

Abstract: the nine points for attention of inspection instrument information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Inspection instrument of nine big note: 1, when using a multimeter ohm block, don't charged measurement. 2, using logical pen, oscilloscope signal detection, to pay attention to not make the probe contact two measuring pins at the same time, because the essence of this kind of circumstance is in. More flow meter manufacturers choose model price quote you are welcome to inquire, here is repair instrumentation nine points for attention of article for details. Inspection instrument of nine big note: 1, when using a multimeter ohm block, don't charged measurement. 2, using logical pen, oscilloscope signal detection, to pay attention to not make the probe contact two measuring pins at the same time, because the essence of this kind of circumstance is in electrical form under the condition of short circuit. 3, testing the power of the filter capacitor, electrolytic capacitor is negative short circuit, first and do not use pens and line instead of a conductor when short circuit of capacitor discharge, because it is easy to burn out the core. Can take a lamp holder leads 220 v, 60 ~ 100 w lamp, connect to the ends of the capacitor, the discharge lamp will flash moment. 4, maintenance in a damp environment instrumentation failure, the multimeter for printing lines point whether tested according to the flow is necessary, because this kind of circumstance is the main failure of copper foil corrosion. 5, overhaul circuit inside the instrument, if the contact and the circuit boards of installing component, the coating insulating varnish, all point measurement parameters available welding on the multimeter pens and ordinary sewing needle, to puncture the lacquer layer directly measure each point, instead of a large area of stripping paint layer. 6, various control panel don't charged plug and plug. Because in electric case, plug panel will produce strong induction electromotive force, then instantly counterattack voltage is very high, the corresponding control panel and the plug is easy to damage. 7 don't blindly, maintenance on touch, lest expanding fault, the repair the bad. 8, removing, adjust instrument, shall be recorded the original position, in order to recover. 9, repairs and precision instruments and meters, if small parts will play fly, should first judge may alight, do not look for east, west look, can take the magnet scanning and the line of sight scanning method. Anyhow, flowmeter in the instrument maintenance work, should first understand the basic principle of instrument and meter, electrical and master relevant knowledge and skills, and should be ready for all instrument specifications, drawings and other technical data, also should form a good working quality, so as to improve efficiency in the instrument maintenance, reduce mistakes. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
