Input Type/Range Setting Function
The Input type/Range setting can be selected for each channel according to the type of sensor to be connected.
Operation
The analog input value is A/D converted or temperature converted by the set input type, input range, or Input type/Range
setting (offset/gain setting), and the value is stored in the following area.
• 'CH1 Digital output value' (Un\G400)
• 'CH1 Digital operation value' (Un\G402)
Setting procedure
Set "Input Type", "Input Range", or "Input Type/Range Setting (Offset/Gain Setting)".
