Figure 3-3 Tolerance mode and Sequential mode
———————————————————————————————————————
Note:
When setting limit values of tolerance mode, the error range should be set
in the order from small to large. If the error range of BIN1 is the largest one, then
all DUT will sort into BIN 1.
Under tolerance mode, the low limit is not necessary to be smaller than the
nominal value and the high limit is not necessary to be larger than the nominal
value. The limit range of each bin can be discontinues or overlapped.

Operation steps for setting the limit mode of the compare function
1)
Move the cursor to the
CMP MODE
zone, the following soft keys will be
displayed.
TOL
This soft key is used to set the limit mode as the tolerance mode.
SEQ MODE
This soft key is used to set the limit mode as sequential mode.
2)
Use above soft keys to set the limit mode.
3.6.3
Set nominal value of tolerance mode
When the tolerance mode is selected as the limit mode of the primary parameter,
it is necessary to set the nominal value. The nominal value can be any one within
