SteREO Discovery.V12 Brief instructions for use
For your safety
Observe the
following
instructions:
−The stereomicroscope SteREO Discovery.V12 including the original accessories may only be used for
the microscopy procedures described in these instructions and in the detailed Operating Manual.

HI P controls
The HI P (Human Interface Panel) allows operation without
SY C OP . The first HI P is used for motorised focussing, the
second HI P for zoom operation. If a SY C OP is connected, the
HI P is not necessary and is only of limited function.
There is a basic mode and a setting mode.
Zoom control unit HI P in basic mode
The display shows the magnification (Mag) and the field diameter
(Field). Briefly press the Mode button repeatedly to display
successively field diameter, resolution and depth of focus.
Zoom value is set by the thumb wheel.
Focussing control unit HI P in basic mode
The header line of the display shows the focus position Z. Briefly
press the Mode button to reset the focus value to zero.
Set the focus position by moving the thumb wheel. Press the
thumb wheel to switch between FocusSpeed and FineFocus.
Parameters in the Setting mode (selected by Mode button)
applies to Zoom control unit only:
Set Lens to change objective variables
Set Eyepiece to change eyepiece variables
Confirmation to switch starting enquiries on / off
applies to both control units:
Zoom / Focus Speed to set the speed of movement
Backlight to adjust background illumination
Beep Level to switch acknowledgement beep on / off
Reset Param? to set on default variable

SY CO P Touch screen controls
The touch screen is a touch-sensitive screen. Press with the finger on
the relevant button to call up the function.
After switching on, the main menu shows the following values:
−Date and time; four short status display windows
−Visual overall magnification (Mag), objective (Obj), eyepiece (Eyep)
−Field diameter (Field), resolution (Resol), depth of focus (Depth)
−Illumination intensity, colour temperature for reflected-light (RL)
and transmitted-light (TL)

Adjusting the illumination
Reflected-light illumination:
•Connect the light guide for reflected-light to the cold-light source
(RL) and attach it to the stand plate or nosepiece (or carrier S).
Alternatively clamp the ring illuminator to the single objective (not
to the nosepiece).
•Switch on the cold-light source for reflected-light (RL) with rocker
switch I.
•Align the light guide on to the specimen.
•Adjust the illumination intensity on the cold-light source or use
the two right hand buttons on SY C OP .
Transmitted-light illumination with transmitted-light unit S:
•Connect the light guide for transmitted-light (TL) to the cold-light
source.
•For lower magnifications, insert the opal glass.
•To avoid dazzle from transmitted-light, swing the dazzle protector
into position.
•Switch on the cold-light source for transmitted-light (TL) with
rocker switch I.
•Adjust the illumination intensity on the cold-light source or use
the two left hand buttons on SY C OP .
•The illumination levers on the transmitted-light unit allow the
brightfield / darkfield to be adjusted as depicted alongside. To
optimise the contrast with oblique light various intermediate
positions can be employed (see explanation of symbols).
Symbols for illumination control
Light beam exits vertically (reflector at 45° inclination)
Inclining the light beam towards the observer (dazzle hazard!) Inclining the light beam away from the observer
Light beam exits centrally Translation of the light beam towards the observer
Diffuse light quality with the white reflector plate Directed light quality with the mirror reflector plate
Adjusting the stereomicroscope
The stereomicroscope should be connected and switched on.
Focus and zoom can be controlled using H I P or S Y C O P . See section
H I P controls or SYCOP controls.
•Place a specimen on the insert plate (3).
•If the dioptric eye values are known, set the eyepieces (2)
accordingly.
•Select the viewing height by twisting the eyepiece support (1) by
up to max. 120° and adjust it to the pitch of individual eyes, i. e.
when looking in the eyepieces only an uninterrupted circle of light
should be seen.
•Tilt the binocular part viewing angle and set it within the range
5° - 45°.
•Open the aperture diaphragm using thumb wheel (4).
•When searching for objects, first set the zoom (5) to the lowest
magnification.
•Focus on a small sharp detail in the centre of the image (6).
•Set the maximum zoom value (5) and adjust for exact focus on the
detail (6).
•Then go back to the lowest zoom value (5) and correct any out-of-
focus separately for each eye, using the adjustable eyepieces (2)
(compensation for variations in the eye).
Once the microscope has been compensated in this way, image focus
will be retained over the entire zoom range.
At the camera outlet of the Ergo phototube (8) a camera can be
attached by a suitable adapter if desired. To change between visual
observation and documentation, swing over the lever (7). The right
hand beam path is switched over completely.
