Assembly and Adjustment Notes
13. R MTV2 (JUS) Adjustment
13.1 Check the internal resistance of the ammeter ''A".
13.2 Add a dummy resistor to make the interval resistance + dummy resistor = 330ohm.
13.3 Set the shutter to "A" and the aperture to f/5.6 (AV5).
13.4 Set the light source to EV 12.
13.5 Install an approximately 500ohm variable resistor as shown and adjust for a current
of 488.25 µA ±7µA.
13.6 Remove the variable resistor. Measure its resistance and install the nearest available
fixed resistor in its place.
13.7 EV 9 : 380.25µA ± 12µA.
13.8 EF Mode : 470.25µA ± 10µA.
13.9 Check the AE Finder Indication
Light Source Aperture
EV 12 AV6 (f/8) TV 6 (1/6C) ± 0.4
EV 9 AV6 (f/8) TV 3 (1/8) ± 0.5
