  ASA scole of the computor occording to  the
   recommendotions of the film monufocturer.

Set the Light Volue scole of the shutter to cor-                 irespond with the Light Volue given by the meter.

 A BRIEF ANALYSIS of whot your exposure meter
is ond how it operotes will help you use it to best
odvontoge. Your meter hos o photo-electric  cell
which converts light energy into electricol energy.
A tiny golvonometer then meosures thot omount
                                                                                                                                                        Iof energy by moving o pointer ocross o colibroted
scole...thus moking on octuol meosurement of light.
  Then, with o computer os provided on the meter,
you relote the light meosurement to the speed or
"exposure index" of your film ond obtoin combino-                           I
tions of f/stops ond shutter speeds usoble forperfect exposures with your comero.                       I
ANY COMBINATION of  f /stops qnd shutter speeds
thus indicoted by the computer on Your meter
results in the some omount of light reoching your
film. Your choice of which combinotion to use
depends on one of two  f octors:  (l)  lf your picture
must " stop " oction or movement, use o combino-
tion with o relqtively  f ost shutter speed; or  (2)
lf you ore more concerned with depth-of-field,
choose o combinotion with o relotively  smoll
f/stop, or lens opening.

   CARE AND USE OF YOUR METER

 Alwoys remember-ybur exposure meter is o delicote
  instrument ond should be treoted os such !  The
  following precoutions will help you give it o long
 ond sotisfoctory life:
DON'TS
  1. Avoid subiecting your meter to ony sudden
      iorring or dropping which con very  eosily
    domoge the sensitive mechonism.
  2. Avoid extreme temperotures.
DO'S
  3. Use thE Choin  f urnished with the meter os
     odded insuronce ogoinst dropping.
  4. Store your meter (pref erobly in  its corrving
     cose) in o sof e, dust-free ploce.
  5. Check " Zero "  setting once or twice o yeor.
     Should you find thot the needle does not register
     "Zero"  when the cover is closed ond oll light
      is prevented  f rom reoching the photo-electric
       cell, the " Zero" odiustment screw on the reor
     of your meter moy be turned in either direction
     to bring the needle to o " Zero" position.
  Proper use of your meter will olwoys give you good
  results.  lf you find thot your negotives or trons-
  porencies ore  regulorly over-exposed you con
  compensote by using o higher ASA INDEX number
  thon thot indicoted by the mqnuf octurer of  the
  film; in the cose of under-exposure, use o lower
 ASA INDEX number. With proper core the " SEKONIC
 LEADER" will give you yeors of qccurote service.
