y
Window. If the zero count is 50,000_10,000, ( 100,000±10,000 for
version 1.06 software) then proceed to step 5.
3 [REZERO]
Press the [REZERO] Key to zero the weight in the Weight Window.
4 [++
++

After computing the zero point, the Quantity Window shows the Zero
Counts. Ensure that the counts are 50,000 _ 10000,
(100,000±10,000 for Version 1.06 software). If not, repeat Step 3 unt

11
Removing the weight, the Unit Weight Window should indicate zero
and the Quantity Window the zero starting point i.e. 50,000,
(100,000±10,000 for version 1.06 software) If the zero point has
changed, please carry out the calibration procedure again.
