A necessary tool and equipment in the process.
Generally, in the process of troubleshooting a faulty smart phone, the working state of the circuit can also be judged through the data displayed by the DC adjustable regulated power supply, so as to provide relevant basis or data reference for fault analysis
be careful
If it is found that the voltage value cannot reach the set value after connecting the electric equipment, then observe whether the current indicator light on the current knob side is on. If it is on, it indicates that the current setting value is too small. Turn the current adjustment knob to turn off the current indicator. If the current indicator remains on when the current knob is turned to the bottom, it means that the power of the electrical equipment is too high or the electrical equipment is seriously short circuited. This is the overcurrent protection function of DC adjustable regulated power supply.
