finish from 9 to 0 press and hold MODE/RANGE key.
2- The display will show “CAL.?_1”
3- Press MODE/RANGE.
4- The display will show “YES”. The platter should be free
from any loads to calibrate the zero point.
5- After zero point is calibrated, the display will show
“LOAD” “XXXX.X” “or” “XXXX.X”
6- Place the weight marker with the corresponding weight
shown on the display. After calibration is finished, the
display will show “CAL.?_2”
7- Press ON/ZERO to exit calibration and return to normal
weighing mode. If there is a need to calibrate the second
point, repeat instructions from number 3 to 6.
