Channel data calculation functions
Function calculation is
performed.
An error occurs when
measured data contains
error data (±OVER, etc.).

2. Integration
The ITG or ITG24 function is used to perform integration operation.
The integration function cannot be used more than once in a formula. Ignoring this causes erroneous calculation.
Combining with another type of calculation is possible.
Example: ITG(1) + ITG(2)
ITG24(1) – ITG(1) ITG(1) / 100
Integration value is reset at every start time and intervals specified in “calculation settings” for ITG function, and at
every start time for ITG24 function.
