INSPECTION OF ENCODER SIGNAL

JAA76251-R.3414.A

� Use an F70(N70) camera body and AF nikkor lens inspection program for F70/N70 to display encoder signal on the computer monitor when making an inspection. Inspection method �Start the AF nikkor lens inspection program for F70/N70 and select "1.READING OF LENS ENCODER SIGNAL". Make inspection according to instructions as shown on the display. �Encoder signals should be as described in the table below when the zoom and distance scale are set to specified positions. � Encodr signal for CPU Version 0.1.1 �MF MODE Zoom ring f = 80mm f = 105mm f = 135mm f = 200mm � (Additioanl)

Distance scale position Infinity position 2.5m Most close distance position 1 72h 2 49h 3 63h 1 72h 2 68h

Encoder signal 3 63h 1 72h 2 41h 3 63h 1 72h 57h 36h 2 6Bh 6Bh 6Bh 3 63h 63h 63h

�AF MODE Zoom ring Distance scale position Infinity position 1 72h 2 49h 3 63h 1 2 f = 80mm f = 105mm f = 135mm f = 200mm
