When incorporating the conversion data into the calculation
BE021 = 200, BE011 = 30
Conversion data: Base distance 10 mm, Base pixels: 85 pixels
Numeric Calculation Calculation results
When using conversion data
CA01 = (BE021 - BE011) * CV11
= 170 * CV11
= 20 20 (mm)
When not using conversion
data
CA01 = BE021 - BE011
= 170 170 (pixel)
Note on incorporation of efficient of conversion data into the calculation
When coefficient of conversion data is incorporate into a calculation, actual calculation is as follows:
CA01 = A * CV11
CA01 = A * Base distance / Base pixel
In the calculation above, if “A * Base distance” exceeds the values that can be used for the numeric
calculation, ( - (2
31
) to (2
31
- 1) ), an ERROR signal is output because overflow error occurs and the
numeric calculation is not perform properly.
Up to 9999999 (7 digits) of base distance can be set, but in this case, if more than 2148 is used for “A” in
the expression above, it results in more than "- (2
31
) - (2
31
- 1) ".
Therefore, if data multiplied by a coefficient (calculation results of the numeric calculation prior to
incorporation of conversion data) may exceed 215, adjust the number of base distance of conversion
data, avoid an overflow error when incorporating the conversion data into the numeric calculation.
Adding a Comment to the Conversion Data
You can add a comment to each conversion data. It would be helpful to enter a comment on the
coefficient of the conversion data for future reference.
1. Highlight the number of the conversion data to which you want to add a comment.
2. Move the cursor to the cell in the Comment column.
