place one stir, and then select the test cup, for example " 1 cup",
select " sample weight" corresponds to the test cup and with "▲",
"▼" button adjust it to "0.000", then the sample weight shows
"blank", as shown in the figure. After press "start" button, the
machine will automatically blank test operation. (Note: to observe

and then take out the cup of blank test.
