Tips-How to do weights calibration
(1) Turn on machine,screen displaying 0.000.press ZEROreturn zero if without showing 0.000.
(2) In 0.000status, Long-press ZEROtill shows up CAL.
(3) Which means it is entering into calibration mode.several seconds later it will automatically show 100.000 200.000along with flickering constantly.place 100g,200g weights onto the centre of measuring bridge.the machine will do calibration automatically.when screen display ENDfirstly,then display100.000200.000.it indicate the calibration is done.
(4) Take down the weights,the machine will return to measuring mode automatically and display 0.000.
