Remarks:
If you do not have precision equipment, do not calibrate the
parameters yourself. If you accidentally perform calibration and
the measurement is not accurate, you can restore the factory-
calibrated default parameters by pressing the menu "Restore
default parameters".
Offline curve function is to use the on-board fram memory to record
voltage, current and temperature parameters for a long time,
generally used for charging curve recording.
For example, the charging curve of the mobile phone can be
recorded in detail.
Steps for using the offline curve recording function:
1.
Turn on offline recording, and the "Offline Recording Time"
menu selects the time you want to record.For example, if the
mobile phone is slowly charged with 1A charging current and
the battery capacity is 3400mAh, the charging time will take
about 4 hours. At this time, the recording time can be set to 5
hours for recording observation.
2.
Setting the offline current threshold means that the current
above this value will be recorded.For example, when the
mobile phone is full, the circuit has a current of 20mA, then the
threshold should be set to 20mA or more, otherwise the offline
data will continue to be recorded continuously, resulting in the
capacity statistics greatly exceeding the battery capacity of the
mobile phone, and the statistics are wrong.
3.
Enter the offline curve interface to delete the old curve data and
start recording again.
