8¡¢Can be calibrated online£¬Convenient for customers to correct errors in time¡£
9¡¢The display LCD screen can be turned off manually.£¬It can also be automatically extinguished after reaching the minimum value of one minute.£¬Need to be always bright, please contact Customer Service¡£
10¡¢Current detection by Hall sensor£¬Pass the wire through the round hole of the sensor.£¬Both positive and negative current can be detected£¬Safe and convenient¡£
Three¡¢Technical indicators
Four¡¢Header interface function and header size
Add four copper columns to make the bottom to insulate the contact between the bottom solder joint and the surface.£¬The size is57*32*50mm£»Modification to remove the copper column requires bottom insulation£¬The size is56*32*44mm¡£
Five¡¢Wiring instructions
The following circuit diagram is the circuit in discharge mode£¬When charging, just replace the load with a charger.£¬No need to change the circuit¡£The current direction enters from the front of the transformer.£¬Current is negative£¬That is, the remaining power of the instrument is reduced.£»On the contrary£¬Current is positive£¬Remaining power increases¡£
