Calibration preparation:
1. 1pc accurate voltage check device;
2. 1 pack of good 6s LiPo battery (cell voltage 4.0V or above).

Calibration steps:
1. using the accurate voltage check device to check the voltage of each cell, and keep the record.
2. power on the charger and only connect the balance lead of the 6s battery to the balance socket.
3. press 'Stop' to return to the main menu and navigate down to 'BATT METER'.
4. press and hold 'Enter' for a while until the voltage unit switch to mV, which indicates the charger can be calibrated.
Attention: calibration is only accessible with the voltage of each cell being at least 3.9V.
5. click 'Enter', the voltage value starts blinking to indicate it is ready to be adjusted and then press 'DEC' or 'INC' to calibrate it.
the adjustable range of voltage is 3.90-4.25V.
