1. Inspection of the internal parts of the transformer: check whether the power elements within the transformer, control of the circuit, etc. Are intact, without visible damage or failure. In case of faulty elements, replacement is required in a timely manner. Check the three-phase output current to detect whether the circuit is working and, if there is a problem, the components need to be repaired or replaced。
Inspection of external factors: consider the effects of external factors, such as environmental factors, on components such as the hole sensor. Adjustments to the working environment or measures to reduce the impact of external factors。
E. The gold analysis tests examine the mass of the plating layer, the thickness and evenness of the plating layer and the binding strength between the plating layer and the copper plating。

Power supply: first, check the transmission lines of the frequency transformer to ensure that the power is stable and the voltage input is normal. Test the input voltage to see if it is stable to remove the power input problem. Instability or power failure may result in the display of the screen not being bright or only in part。
2. Bad signal line exposure: checks whether the endpoint of the signal line of the mutator is loose or broken. This may result in the frequency display screen not being bright or only partially visible. Reconnect the signal line to ensure that the end of the signal line is secure。

3. Output and electrical control: a one-size-fits-all gauge is used to measure the electrical output line of the frequency transformer to see if, in the case of electrical power, it has an electrical output control. At the same time, an on-site observation of the electrical power is made to determine whether the output is normal。
4. Electric insulation and internal circuits: measuring electrical insulation to ensure that the power plant itself is not damaged. In addition, the examination of circuits and devices inside the transformer, such as voltage-relief resistance, mos tubes, diodes, etc., may affect the display of panels。
5. Control of input power and signal: dismantling of the frequency wiring panel and measuring of input power by the variable. At the same time, the control signal, including the output signal and the feedback signal, can be checked and, if necessary, the frequency reaction can be judged by trying to short-link or break the switch signal or by entering an output analogue signal。
Zui filtering of power is effective by setting filters on the communication power lines. In order to prevent the coupling or looping of conductors, the input and output lines of the filter should be drawn from both sides of the sensor and the lead lines should be as short as possible。
In the case of direct laser imaging, no photographic film is required, whereas images are formed directly from lasers on the light sensitivity membrane. Ultraviolet light is used for operations, so liquid preservative solutions meet the requirements of high resolution and simple operations. No photographic film is required to avoid adverse effects due to film defects, which can be linked directly to cad / cam, thereby shortening the manufacturing cycle and making it suitable for small and multiple production. An important topic in the electronic manufacturers ' community is the erosion of circuit boards in transformers. This is what every e-fever guy does when he walks into the world of electro-diy. Although it appears simple, it does require certainty and persistence, as the process produces dangerous chemicals with strong odor。
The board must be unloaded for inspection, which may damage the connector or cause other treatment
If the set-up is incorrect, an alarm occurs。
