4.3 Sorting the Part (Comparator)
4-13 ZM2371/ZM2372

Enabling/disabling the range comparison
To make comparison using the comparator, set not only the upper/lower limit value but also
“ON or OFF” for the comparison.
If the cursor is at the position of ON/OFF, it is able to set “ON or OFF” for the comparison of
primary parameter’s Bin or secondary parameter where the cursor is placed.
Examples of range comparison:
when the cursor is at ON/OFF position
< B I N 11 O F F L o : + 1 . 2 3 4 5 6 µ F H i : + 1 . 2 3 4 5 6 µ F >
Current setting
0 ) O F F 1 ) O N
Options
ON
Enables the range comparison for one set of upper/lower limit values
OFF Disables the range comparison for one set of upper/lower limit values
When the comparison of secondary parameter is disabled, the comparison for secondary
parameter is not conducted but only the comparison for each Bin of primary parameter can
be done (S-LO/S-IN/S-HI and S-NG are not output).
When “OFF” is set for specific Bin of primary parameter, the comparison for LO/IN/HI for
that Bin is not conducted and the DUT is not sorted into that Bin. When such setting is
made that the comparison for all Bins (1 to 14) of primary parameter is not conducted, the
DUT is always sorted into “OUT OF BINS”.
Note that, even if range comparison is set to “Enable(Valid)”, it cannot be sorted for the
given Bin in case of lower limit value
≧
upper limit value.
Substantially the comparison for upper/lower limit value is not conducted.

Disabling only either side of lower or upper limit
_ SHIFT _ + [ NO LIMIT ]
With the comparator upper/lower limit setting menu, pressing the
_ SHIFT _ + [NO LIMIT]
keys causes the comparison of the lower or upper limit value on cursor to be disabled and
the comparison is not conducted.
< B I N 2 O N L o : + 1 . 2 3 4 5 6 µ F H i : N o l i m i t >
Once both of lower and upper limit values for the Bin (primary parameter) are disabled, it
becomes the same state as is the case when the range comparison of Bin is disabled.
Once both of lower and upper limit values for the secondary parameter are disabled, it
becomes the same state as is the case when the range comparison of secondary parameter
is disabled.
