Your new flash meter is a most accurate instrument, using state-of-the-art technology to
                                                         several electronic flash units (strobes). lt.measure the momentary flash burst(s) of one or
 is particularly useful in bounce and multiple strobe setups where exposure cannot be easily
determined on the basis of calculations.                                                                                .
 * The flash meter uses a high efficiency silicon photo diode (SPD) of great accuracy and
'  with high sensitivity characteristics. Using a highly sophisticated lC with an autornatic '   measuring system,  it gives quick and reliable readings of incident flasfi^llgnfiXflgry*

   measuring flash(es). The peak-hold display, indicating the reading obtained, stays lit
    until the ON/OFF switch is re-set.
x Thanks to its white hemispheric integrator design the receptor dome provides wide angle
    coverage for incident light sources.
 * Power source: One(1) 9 volt battery type 006P. Battery checking can be done with the
  LED pilot lamp(a).  lf the LED lights when the switch is in theON position, the battery
     is in good condition. The pilot lamp is also the battery condition indicator; if it fails to
    light with the switch (2) 'ON', replace the battery.
 * The pilot lamp will flicker when the F stop indication is in over-range (over exposure)

              Make sure the battery (a stan dard 9 volt 006P,
                  Eve ready 522, or Mallory MN 1604 type battery)

                     2. By sliding the white index"pointer(8), set the
              ASA/D IN film speed number in accordance with
                 the rating of the film you are using. Note that
                  the uppermost position, directly agr_gg the ASA/
               DIN engraving, is tbp on€*fisd$ fb      /DlNg.
                     3. Hold the flash meter close to the principal spot
             or area of the su bject you wish to measure,
                   pointing the Iight receptor dome (3) in the direc-
                    tion of the camera.
                   4. Slide the switch on the side of meter to the ON
                     position. The pilot lamp (a) will light.
               5. Now trigger the flash or flashes. The meter will,
               upon detection of the flash, dir'ectly and without
                any calcu lations, indi cate the nearest full F stopstOFF               on the ex posu re scale.

               F22. lf the incident light value is in excess of

F22, the pilot lamp(4) will flicker. In such a
   case, reposition the flashgun or flashguns in order
  to decrease th e am ou n t of   I igh t wh ich  fal ls on
   the su bject.
7. Bpfore taking another reading, re-set the meter
   by actuating the ON/OFF switch.
8.  lf yqu wish to trigger the flash from the meter
   position, connect the accessory E E sync cord
   betw$en the flash meter and the ftash unit. In
   this case, the flash will fire as the ONIOFF
   switch is activated, with the meter providing an
   automatic reading of the flash intensity.
                                                                                                             f or th is9. The E E sync cord , vff optional accesso ry
   flash meter, uses an electronic buffer circuit at
   the flash end of the cord to minimize cord resist-
  ance effects and to assure reliable and precise
   operation of the strobes triggered by means of
   the cord.

  -optical and electronic instrument it is. Avoid storing the meter in places subject to extremes
   .in temperature or humidity, avoid dropping or bumping it.
    lf you expect not to use the meter for an extended period of time, the battery should be
   removed.
