The Digiflash is a small but smart GOSSEN exposure meter, with digital read-out,
for ambient light and flash. The Digiflash is
made to exacting GOSSEN calibration
standards for high precision measurements. The trendy styling and logical functioning make it easy and comfortable to
operate. Key features:
• Incident and reflected light meas. mode
• Measuring of ambient and flash light
• µP controlled
• Digital LCD read-out in the display
in 1/3 stop increments
• Contrast readout in 1/3 EV steps
• Storage of the measuring results
• Indication of all suitable combinations
of shutter speeds and f-stops
• Signal "range over" or "range under"
• Automatic battery check
• Countdown timer for long exposures
• Function Watch/Alarm clock
• Measuring temperatures
1 The functioning of the Digiflash
1.1 Preparation and self-test
Battery
The Digiflash is powered by a 3 V Lithium
battery, type CR 2032. When the battery is
running low, BAT appears in the display.
– The battery should be replaced as soon
as possible. When BAT is shown alone
in the display, the battery will need to be
replaced before further measurements
are possible.
– To replace the battery, pull out the battery
compartment located under the eyelet for
the carrying cord.
– Remove the old battery and insert the
new one. Observe the "+" and "–"
polarity!
– Close the battery compartment
Attention! The Digiflash is provided with a
battery memory of 10 seconds. If the battery
is removed briefly or replaced only within
GOSSEN Foto- und Lichtmeßtechnik 4
those ten seconds, the values stored in
memory will be maintained. Otherwise
changing the battery or pressing one of the
buttons will cancel all the individually stored
values.
Self-Test
After the new battery has been inserted,
the microcomputer will carry out a self-test.
Every display segment appears in the
display panel. The self-test takes 10 seconds. It can be interrupted before by pressing any button.
After the self-test, the standard settings will
be shown as set by the factory.

1.2 Incident light and reflected light Incident light method
For the incident mode, the diffusor is to be
shifted to the left and placed in front of the
measuring aperture. Taking measurements
using the incident light mode in particular
produces in most cases perfectly exposed
shots. In this mode, the DF measures from
the subject towards the camera. This guarantees that the tone quality of the picture is
equivalent to that of the subject. This is especially important for very bright or dark
subjects. Even under very difficult lighting
conditions, as e.g. with subjects which have
a lot of contrast, the incident light mode is a
more reliable way of producing well exposed pictures.

Reflected light method
For the reflected mode, the diffuser must be
shifted to the right. Care must be taken, that
the light sensor is entirely free.
The measurement is taken from the position
of the camera towards the subject. In this
method, only the light reflected from the
subject is detected by the meter. Therefore,
the measuring values always depend on the
reflection capacity of the subject. As a result
of this, bright subjects are reproduced
darker and therefore not properly exposed.
Consequently, this mode is conveniently
used, when the suject does not show too
high contrasts between bright and dark
areas.
1.3 Duration of read-out in display
The Digiflash will always display the last
function used. The meter does not
automatically switch off, as the power
consumption is extremely low.
2 Functions of the Digiflash
Press the function button for selecting the
individual functions of the Digiflash.
Each time the button is pushed, the next
function will be activated.
2.1 Setting the film speed
– Select the function "Exposure ambient
light" and hold down the function button
until the OK-signal sounds. The display
will show ISO, blinking.
The display panel will show the functions in
the following sequence:
• Ambient light
• Fl ash light
• Timer
• Watch
• A la rm clock
• Temperature
The next function will only be activated after
the Function button has been released.
When the Function button is kept pressed
down for more than two seconds, the
settings of that function are displayed and
can be adjusted as desired.

– Use the measuring key M to select the
desired film speed.
When holding the key M pressed down,
the film speed will automatically be
increased. When getting close to the
desired ISO value, release the key M
and set the desired film speed by pushing
the key in individual steps.
Each time you push the key, the film
speed is increased by a 1/3 stop.
