Your Starlite is the top device in the GOSSEN-
product range and represents a real all-in-one light
meter. It combines a light meter for ambient and
flash light, a CINE meter for cinematographers as
well as a measuring instrument for lighting technology and photometry. And the clarity of the operating control elements and the digital display is still
preserved. Functions used over and above the
normal metering can be individually integrated by
the user.
The Starlite can be easily converted into a complete CINE meter for the cinematographer and
their needs.
Due to the microprocessor technology, the user
benefits from our knowledge on lighting technology
which we have gained over decades of experience
in the construction of light meters.
As a result of its precise calibration, the Starlite
provides very accurate measuring results and is
easy to operate.
Characterising of the Starlite:
– Splashwaterproof housing
– Digital stop display in 1/10 stop increments
– Automatic display illumination
– Shutter speeds in full or 1/2 time values
– Second ISO value
– Incident light measuring
with spherical/flat diffuser
– Reflected light measuring, option of 1° or 5°
– Flash measuring (cord/cordless)
Display of the ambient light portion
Flash calculation with different measuring times
Flash calculation for multiple flashes
– Analogue contrast display
with f/stops in 1/2 stop increments
– Averaging of up to 9 measuring values
– Storage of settings and measuring values
– Configurable EV correction
– Measuring in accordance with the zone system.
Direct display of the measuring values on the
zone scale
– Special CINE meter, settable for shutter angles
other than180 degrees, conversion
with formulas is not necessary
– Funtional range of photometry
Measuring of illuminance
and luminance with ambient and flash light
– Key lock

1 Preparation
1.1 Battery
The Starlite works with a 1.5 V AA battery
(Alkaline-manganese or corresponding
rechargeable battery).
When the battery is running low, the display
appears in addition to the measured values as a
warning to the user.
At this stage, it is advisable to replace the battery
as soon as possible.
When appears on the display alone,
measurements can no longer be taken.
Replace the battery immediately.
To replace the battery, open the battery compartment of the Starlite, remove the old battery and
insert the new one. Observe the "+" and "–"
polarity! Please close the cover of the battery
compartment.
1.2 Self-test
After the new battery has been inserted, the microcomputer will carry out a self-test. Here, every
display segment of the display panel appears.
The self-test takes about 10 s. It can, however,
be interrupted before by pressing any button.
As soon as the self-test is complete, the factory
preset standard settings are activated.
Warning!
Do not view and do not aim the meter
directly at the sun
You may not only damage your eye, but also ruin
the light-sensitive cell.

In addition to the standard functions, your Starlite
features a range of additional characteristics and
functions which can be selected using the
"DIP switches" in the battery compartment.

2.1.1 Automatic display illumination
When the lighting conditions are poor (about EV 4
or less), the background lighting of the display is
switched on automatically for 10 seconds.
2.2 Display duration
If the Starlite display panel is idle for about 2
minutes, it is switched off automatically.
The measuring values and the preset values
remain stored in memory.
– By pressing anyone of the buttons, you can
recall the measuring value from the memory.
– By pressing the measuring button , a new
measurement is taken.
The measuring values of the last measurement
remain stored in the memory until a new measurement is taken.
The Starlite has separate memories for
ambient and flash light measuring.
2.3 Key Lock
It makes sense to activate the key lock to avoid
switching on the Starlite by accident.
– Activating the key lock: press
ISO and ISO2 simultaneously.
OFF, ISO and ISO2 appear for 3 seconds on
the display. Then the instrument switches off
automatically.
If you press any button, OFF, ISO and ISO2 are
displayed again for 3 seconds.
– Deactivating the key lock:
press ISO and ISO2 simultaneously.

3 Operating elements
3.1 ISO – ISO2
Selecting the film speed
You can select two different film speeds with the
ISO and ISO2 buttons.
– Select the film speed by pressing and holding
"ISO" or "ISO2". ISO or ISO2 will flash on the
display panel.
– Set the desired ISO value using the setting
wheel.
When another operating function is selected,
the preset film speed is retained in the St arlite
memory.
The film speed you have selected, either ISO or
ISO2, appears in the top right corner of the display
panel (ISO2 as long as the ISO2 button is pressed).
When the ISO2 button is pressed, the converted
shutter speed/f-stop values are displayed on the
basis of the last measuring. Therefore, you no
longer have to carry out time consuming calculations when working with 2 films of different speeds.
If the film speed is changed, the last measuring
value is converted to the new ISO settings.
The selected film speed is memorized until it is
changed in accordance with the above mentioned
procedure.

after measuring. Multiple flash calculation
– Allocation of zones
– Selection of shutter angles in the CINE function
