weight on the pan and the display will stop
blinking and after 4 seconds display will
show “400.00” blinking with weight still
on the pan put another 200g of weight to
make the total weight 400g, now again
the display will stop blinking and after 4
seconds d isplay wi ll show “600.00”
blinking, with weight still on the pan place
another 200g 50 make a total of 600g and
