Shift adjustment function
Adjusts the analog value zero point using the UP/DOWN keys for shift
adjustment.
Holding down the UP/DOWN keys to change the shift value faster.
Pressing the ZERO RESET key for 2 seconds cancels the shift adjust-
ment value, and 0 V (12 mA) is output when the target is at the reference
position.

FUNCTIONS SHIFT/SPAN
Span adjustment function
Adjusts the analog value inclination using the UP/DOWN keys for span
adjustment. Use the span adjustment when the sensor head is tilted or
the target surface condition affects the analog output characteristics.
Holding down the UP/DOWN keys to change the span value faster.
Pressing the RESET key for 2 seconds cancels the span adjustment
value, and the output characteristics are reset to the factory-set values.
