5.Introduction of the Main Functions
Input Type and Calculation
As shown in the table below, the available input types are analog input, which
includes DC voltage, thermocouple, and RTD, and other inputs, which consist of
pulse signal (1 channel) and logic signals (2 channels).
In addition, the arithmetic calculations between two inputs can be performed and
assigned to a calculation channel and displayed in the same fashion as measured
values. The statistics of measured values can also be displayed.
For details on the input settings, see chapter 5, “Setting the Input Channels.” For
details on calculation, see chapter 8, “Setting the Calculation of Measured Data.”
