when data entry work is required, a worker presses the input function button 73, the recorder records the current numerical value in the storage module 101, and the serial number of the storage battery is increased by one;
when the last recorded data needs to be deleted, the staff presses the delete function button 72 to enable the storage module 101 to delete the previous recorded data;
when the next group of storage battery data recording is needed, the worker presses the next group of function buttons 71 and adds one to the number of the recording groups;
when the voltage/internal resistance data of the storage battery needs to be switched and recorded, a worker presses the voltage/internal resistance measurement change-over switch 4 to change the type of the measurement data;
step 2: the recorder sets a threshold value, when the voltage detection sensor 2 detects that the voltage fluctuation is within a certain percentage of the set voltage value and exceeds or is lower than the maximum value and the minimum value of the set threshold value at the same time, if the input function button 73 is pressed, the buzzer and the power supply and signal module 83 thereof respond and send out a buzzing prompt.
When the set of function buttons 71, the delete function button 72, and the input function button 73 is pressed, the voltage amount and the operation mode are written in the storage module 101, and after the writing operation is completed, the microcontroller 6 sends a command to the LED operation indicator lamp power supply and signal module 82 to turn on the LED operation indicator lamp 81.
It should be noted that, when the input function button 73 is pressed, if the voltage detection sensor 2 detects that the voltage fluctuation is within a certain percentage of the set voltage value and exceeds or falls below the set threshold value, the buzzer and the power supply and signal module 83 thereof buzzes for prompting.
When the voltage/internal resistance measurement switching button 41 is pressed, the two-color LED indicator lamp 51 switches the light color according to the measurement data at that time.
The storage module 101 has a function of transmitting the storage battery record data to the outside through a medium.
