4.1.7. Battery Calibration (C-8)
(1) Pressing and holding “Calibration Switch” press [POWER] key.
After “CAL” message blinks three times and shows the version of scale, it displays “CAL 1”
message.
(2) Press [ZERO] to display “CAL-8”.
(3) Press [TARE] key and then it displays voltage of battery.
(4) Change the jumper-pin of main PCB, ‘BAT’ to ‘+5V’.
(5) Press [ZERO] key two times and then Press [-] key two times.
And then it display ‘500’
(6) Change the jumper-pin of main PCB, ‘+5V’ to ‘BAT’.
(7) You can see the calibrated voltage of battery.
