the counter is reset to 0 by itself at startup. to weigh something that is on a plate, simply place the empty plate on the scale, turn the scale that moves to 0 with the top plate, then put products for weighing. Or do the reverse, weigh it all, turn on the scale, empty the plate and putting the top plate, the difference is products is shown in reverse
Packaging is a bit light but adequate. The surface is a little messy. Very good price / quality ratio
