Chapter 14 Numerical Calculations

14-1 Outline

Numeric calculation function of the IV-S30J consists of "numeric calculations," which is set individually
for each measurement program, and "final numeric calculations," which are set according to object
type. The N00 to N15 results of the calculations which are set individually for each measuring
program may be used according to the "TYPE" and "FORMULA" settings of the final numerical
calculation.

14-2 The individual numerical calculations for each measuring program

How to display the numerical calculation conditions setting screen
There are two methods for displaying the numerical calculation conditions setting screen.
1) Select "MAIN COND" -> "OBJECT TYPE
COND" (menu tree) -> "TYPE00" -> "MEA-
CND (CAMERA1)" -> "MEAS(NEW)," in that
order. On the "
select any of the measurement programs.
Note: When "
to "NO," you cannot specify a numerical
calculation function.
On either the MEAS CND, or REG-COND
screen, press the TRG/BRT key to move the
cursor to the upper function menu. Select
"COND" and then from the popup menu, select
the "NUM-CALC" item.
Note: The items shown in the popup menu will
vary with the measurement program
selected.
2) Open the sub menu for "MEAS0" or "MEAS1"
on the menu tree, and select "NUM-CALC."
Then press the SET key.
Note
- Numeric calculation errors (deviation from the exact value) after digitizing the image
Since the IV-S30J` uses 64-bit, floating-point arithmetic operations in its calculations, small
quantization errors may occur when converting the images into numbers.
