Your new flash meter is a most accurate instrumint, using state-of-the-art
       technology to measure the momentary flash burst(s)'of onE or several       electronic flash units (strobes).  lt  is particularly useful in bounce and
       multiple strobe setups where exposure cannot be easiiy determined on theH       basls of calculations. A single flash readlng also piovides exposure infor-       matlon for multiple flashes right on the exposure scale.
         *The flash meter uses a high efficiency silicon photo diode (spo) or
           great accuracy and with high sensitivity characteristics. using a
           hlghly sophisticated lc with an automatic measuring system it glves           guick and reliable readings of incident flash illuiination.
        *A red   ;LED provides an easy-reading bar graph (dot mode) display of the             ; f/stop number to be used when measuring flash(es). The pea-k-hold
          display' indicating the reading obtained, stays lit  until the meter           is re-set.
          :tThanks to its white hemispheric integrator design, the receptor dome
           provides wide angle coverage for incident light readings. Reflected          readings (off an 18? grey card) may also be made by fiist  sliding
          the hemispheric diffuser away from the receptor.           ,rPower source: One (l) 9 volt battery. Battery checking can         be done with the LED pilot lamp (4).   lf the LED lights when the switch
           is in the 0N position, the battery is in 9o6d condition. The pilot          lamp is also the battery condition indicator; if  it fails to light with          the switch (2) t0Nt, replace the battery.

*The pllot  lamp will  blink when the f/stop indication is in over-range
    (over exposure) untll  reset.
        c ru--,l. Open the cover of the battery compartment (at the bottom of the case)
   and insert the battery.   lilake sure the battery is loaded correctly accord-
   ing to the polarity  (+) (-)  indication.
2. Set the film speed by rotating the ASA/DlN dial  in the window (7).  The
   appropriate film speed is indicated on film box.
3. Hold the flash meter close.to the principal spot or area.of the subject
   you wish to measure, pointing the light  receptor dome (l)  in the direction            II   of the camera                                                                                                                                                                                                                                                            I
4. Slide the switch on the side of meter to the 0N position.  The pilot                    I
   lamp (4) will  light.
5. Now trigger the flash or flashes.  The meter will,  upon detection of the
   ffash, directly and without any calculations, indicate the nearest half  f/
   stop on the exposure scale.
5. The minimum aperture indication at ASA 100 is f/32.    lf the incident
    fight value is in excess of t/32, the pilot  lamp (4) will  flicker.    In
   such a case, reposition the flashgunwww.butkus.usor flashguns in order to decrease
   the amount of light which falls on the subject.

7. Before taking another reading, re-set the meter by pressing the RESET
    but ton  .
8.  lf you wish to trigger the flash frpm the meter position, connect the
   accessory sync cord between the flash meter and the flash unit.   In this
   case, the flash will  fire as the 0N,/0FF switch is activated, with the meter
   providing an automatic reading of the flash intensity.
9. The Strobe Meter uses an electronic buffer circuit  to minimize cord re-
   sistance effect.s and to assure reliable and precise operation of the
   strobes triggered by means of the cord.
l0.The effect of repeated flashes may be extrapolated from a single flash   reading. Turn the outdr dial so that the I'lil indicator is positioned
   over the lit  LED. Read the required number of flashes opposite the
   desired f stop (to the left  of the indicated exposure).

CARE AND STORAGE
Your Flash Meter is precision-engineered to provide years of accurate and
reliable service. While the all-plastic  body requires no special care, the
meter should be treated like any other fine optical and electronic instrument.
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, remove the
battery
