Setting up limit ranges
Notes on setup
• If you set up the upper limit value to a value equal to or less than the lower
limit value, the limit range is not used. This operation is equivalent to
setting the limit range to OFF.
• If BINs overlap, the resulting measurement is sorted into the BIN of the
smallest number (refer to Figure 7-5, “Sorting judgment flow,” on
page 133). Therefore, you need to set up the limit ranges starting from the
narrowest to the widest as shown in Figure 7-2.
• For the tolerance mode, the reference value is not required to be within the
limit range (between the lower limit value and upper limit value).
• Gaps between the limit ranges are allowed. Therefore, you can set up the
limit ranges as shown in Figure 7-3.
