4.3.4.2 Swap Parameter Function
The swap parameter function is used to swap the primary parameter for the
secondary parameter in the FUNC field. For example, when the measurement
function is Cp-D, the swap parameter function sets the measurement function to
D-Cp. Then the comparison limits for D are a maximum of 3 pairs of comparison limits,
and the comparison limits for Cp are now one pair.
Front Panel Operation for Swapping Parameter Function.
Perform the following steps to swap the primary parameter for the secondary
parameter.
1) Move the cursor to the FUNC fied. The following softkey will be displayed.
 SWAP
2) Press SWAP to swap the primary parameter for the secondary parameter.
3) Press SWAP again to return the measurement function to the previous
combination.
4.3.4.3 Comparator Function's Limit Mode
There are two methods used to specify the tolerance mode limits, the ratio in percent
and by parameter value.
Front Panel Operation for Setting the Limit Mode for the Comparator.
Perform the following steps to set the limit mode for the comparator.
1) Move the cursor to the MODE field. Then the following softkeys will be displayed.
 % TOL
This softkey is used to set the limit mode to the tolerance mode (the ratio in
percent).
 ±TOL
This softkey is used to set the limit mode to the tolerance mode (parameter
value).
2) Select and set the limit mode using the softkeys.
4.3.4.4 Comparator Function ON/OFF
This function is the same as the function on the BinNo. Disp Page (Refer to 4.3.2.1
Comparator Function.)
4.3.4.5 Auxiliary bin ON/OFF
This function is the same as the function on the BinNo. Disp Page. (Refer to 4.3.2.2
Measurement Function.)
4.3.4.6 Low/High Limit Value
TH2816B's built-in comparator can sort devices into a maximum of 4 bins (BIN 1 to
BIN 3, and OUT OF BINS) using a maximum of 3 pairs of primary parameter limits
and one pair of secondary parameter limits. These primary parameter low/high limits
can be set in the BIN 1 to BIN 3 LOW/HIGH fields, and the secondary parameter
low/high limits can be set in the 2nd LOW/HIGH fields.
Note: Do NOT enter a value which is lower than the LOW limit into the HIGH limit.
If you do, the warning message “Warning: Low>High” will be displayed (this
isn't an error), and TH2816B will not sort a DUT into the warning BINs you
specify.
Front Panel Operation for Setting the Low/High Limits
Perform the following steps to set the bin sorting limits.
1) Set the measurement function for the comparator function, the nominal value,
