1.1 Preparation and self-test

Battery

The Digisix is powered by a 3 V
Lithium battery, type CR 2032.
When the battery is running low, the signal
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 placed 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! Changing the battery will cancel
all the individual values stored in memory.

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 measuring mode
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 perfectly exposed shots. In this
mode, the DS 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 photographying

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.
conditions, as for example 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 measuring aperture is entirely free.
