 PREPARINGMETER FOR OPERATION
Battery check: Place a battery in battery chamber @ correctly,
  and switch the meter ON @. Then b.c. mark and bar symbols
  are-displayedfor a second. Number of bar symbols shows degree
  of battery capacity. lf battery is weak to give correct readings,
  b.c. mark is blinking or disappears.
  After checking battery the display is automaticallychanged to
  measuringmode.
Setting film speed: To set ISO sensitivatyto the film you are usang,
  switch the meter ON and press either side of UPIDOWN key
 @ while depressing ISO selecting key @.
Setting shutter speed: This meter is designed for T (shutter speed)
  priority use. Therefore, shutter speed should be set first except
  the meter is used in EV mode.
  By pressing either side of UPIDOWN key, display of shutter
  speed is changed accordingly.
Sefecting measuring mode: By pressing F/EV selecting key @,
  measuring mode can be converted from F mode (combination
  of F-stop and shutter speed is displayed)to EV mode (EV number
   is displayed),or vice versa.



 MEASUREMENTAND READ.OUT
Incident light measurement
  1 . For measuring ambient light: Mount Lumisphere @  to swivel
    head O. Switch the meter ON and point Lumisphereto the
    camera from the position where subject is to be measured.
     Press measuring switch @. Then measured value of F-stop
     or EV is displayed.

  2. For measuring illumination contrast: Mount Lumidisc @
     to swivel head. Switch the meter ON and point Lumidisc
     directly toward center of main light. Press measuring switch
      in EV mode and read-out the measured value.
     In the same manner, read the EV number of  fill-in light.
     Difference between EV numbers of main and fill-in lights
    becomes contrast ratio (refer to Table 1).
  3. For measuring luminance (Lux) : Set ISO sensitivity.to ISO
    100 regardless of your film speed. Place Lumidisc parallel
     with the measuredsurface and read EV number in the same
    manner as for other measurements.
    As to Lux value corresponding to the measured EV number,
    please refer to Table 2.
Reflected light measurement: Mount Lumigrid @  to swivel head.
  Switch the meter ON and point Lumigrid directly toward part
  of subject to be measured. Measure reflected light from main
  point of subject as close as possible to the subject.
  Use adequatecare in this case that the meter shadow does not
  interfere with the light to be measured.
Post- measurement calculation
  1. Calculation dependent upon change of film speed can be
    made by pressing either side of UPIDOWN key while depress-
     ing ISO selecting key.
  2. Calculation dependent upon change of shutter speed can be
    made by pressing either side of UPIDOWN key only.
  3. Conversion of measuring mode can be made by pressing
    F/EV selecting key.
Measuring range: When measuring range is exceeded, F-stop or
  EV number will be replaced E.o (error-over)or E.u'(error-under)
  mark.
Measurement for movie camera: Procedure for taking measure-
  ments when using movie camera is the same as for taking ambient
  light measurements.
