16. Math Expressions and Totalization
Remarks Math expressions and totalization
This section outlines math expressions and totalization. For programming, read the separate instruction manual for “Math Expressions and Totalizations (Option)”.
1Math Expressions
(1)Measured values are computed and the results are displayed and stored into memory.
(2)Math expressions comprise basic calculations, totalization, flow rates, etc., which are depending on the relevant model code.
(3)18 types of math expressions are provided and they can be programmed to any channel.
Basic calculation
Totalization, flow rate, etc.

Totalizing
(1)Measured values and computed results are totalized and the results are displayed and printed. The reset of the totalization is executed with the programmed interval or a contact signal for the “remote contacts” (option).
(2)Totalization is displayed as “int”. This can be programmed to any channel.
