2. Set the span for Ranges 1 to 4.
3. Set the hysteresis value.
DO/DI Setting
• Follow the procedure in 8.2.14 “Digital I/O Function” and set the DO for Range output.
• When using the multi-range switching with external signals, set the DO for external
range switching signals.
• Requirements to combine the range signals (No.1 and No.2) to set the DO and DI differ
depending on the Range Type. For details, see the explanations (1) to (5) on the
