LINEAR OUTPUT ADJUSTMENTS
Choose adjustment methods setting LINEARITY adjuster. Adjustment LINEARITY adjusters must performed with standard target positions 100% rated detecting distance away from sensor.
Linearity Adjustment Method
standard target rated detecting distance away from sensor.
Linearity Adjustment Method
Connect ammeter across terminals illustration shows sensor connected amplifier through socket P2CF-11. Turn LINEARITY adjuster counterclockwise that SPAN indicator remains OFF. Then slowly turn adjuster clockwise until indicator illuminates. Stop turning adjuster position where SPAN indicator illuminates.

Place standard target rated detecting distance away from sensor unit.
Slowly turn LINEARITY adjuster clockwise until SPAN indicator goes OFF. Then turn adjuster counterclockwise until indicator illuminates. Stop turning adjuster when SPAN indicator illuminates.
Turn LINEARITY adjuster slowly clockwise increase output current) counterclockwise decrease output current). adjuster position that reads output ammeter.
SENSITIVITY ADJUSTMENTS
Place standard target specified position. target moves parallel with surface sensor unit, make adjustment after determining position using following procedure.
Place standard target rated detecting distance.
Adjust linear output according Adjustment Method
Turn LINEARITY adjuster slowly clockwise increase output current) counterclockwise decrease output current). adjuster position that reads output ammeter.
Calculate detecting distance using following formula: setting distance Adjust distance between sensor object detected distance
