Your Starlite is the top device in the GOSSENproduct 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

1.1Battery

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.

1.2Self-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.

ISO	100/21°		0/1.0
ISO2	50/18°
f	5.6	t	1/125
EV	12	Flash	f 1/60
f/s	24

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.

1.3Selecting the function groups:

DIP switches in the battery compartment

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.

– DIP 1 Selection STILL – Photography CINE and PHOTOMETRY

–DIP 2 Selection SHUTTER SPEEDS (1/1 or 1/2)

–DIP 3 Selection DISPLAY UNIT photometry

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.

2.2Display 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.

2.3Key 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

3.1ISO – 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 Starlite 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.

3.2Function

With the function buttons you can select the measuring modes ambient light or flash light . Keep the function button pressed and select the sub-functions time preselection t, f-number preselection f or exposure value EV using the setting wheel.
