Auto-reference function
When CH2 is set to auto-reference, the threshold of switch output can be read by external input or button operations. The threshold is changed
automatically when the threshold of switch changes, such as when workpiece changes. The input value is the flow rate when the external input
is turned ON.
The switch setting of CH2 is disabled during auto-reference operation.
