How to find the failure of digital push force meter How to find the failure of the digital push-pull gauge, the digital push-pull gauge is a test instrument commonly used in our daily life, but when we use it, it will inevitably lead to failure, then how to find the fault of the digital push-pull gauge, Heng Gang push force gauge Xiao Bian also saw a lot of online friends leave a message that they did not know how to find the fault of the digital push-pull gauge. In order to solve this problem raised by everyone, today Heng Gang push-pull gauge Xiaobian made it The fault finding method of this digital force gauge is expected to help everyone The first kind: circuit parameter measurement method Electronic digital push-pull force meter Users can use ten thousand meters to measure the current and resistance of each point of the circuit, and the voltage is compared with the normal value to determine the fault location. If necessary, it can be compared with the new whole digital electronic force gauge to judge the fault. The second: the intuitive method Electronic digital push-pull force meter users can intuitively find the fault site by hand, eyes and ears. Such as virtual welding, component touch, broken wire, poor contact of plug-in components, overheating of components, ignition of smoke, burning paste, lack of oil, mechanical transmission parts wear, clearance is too large or rolling, abnormal noise and so on. The third kind: test inspection method The use of special test instruments to test the whole digital electronic push-pull force meter or part can often effectively detect the fault and improve the repair quality. Fourth: cutting method Remove doubtful circuits from the entire electronic digital force gauge or unit circuit, and gradually narrow the fault search range. If the operating current is too large or there is a short circuit, disconnect some of the circuit from the whole machine and see the current change. To determine whether this part of the circuit is normal. Fifth: Electronic digital force gauge replacement method For suspected components, plug-ins, and replacement of their work with the normal counterparts, the purpose is mainly to narrow down the scope of fault finding. Faulty components can be found during replacement. Sixth: Electronic Digital Force Gauge Waveform Method Users can use the oscilloscope to observe the waveform of the instrument circuit and components and compare it with the normal waveform to judge whether the power is working properly. The above six fault finding methods are summed up by Heng Gang Xiao Bian. If you have a better method, you are welcome to respond at any time.
