6. 2 Accumulative operation
Put the weighing item on platter， wait for the weight reading to be stable, press the M+
key，the window will show total x，this is current total value.
6. 3 Account operation
To enable the change function on, see parameters F12 change > on
After do accumulate operate, you can press CH key, WEIGHT window will show the
