SO-5000 Ophthalmic Microscope
1.
The power supply is switched on by depressing the switch (E) on the front panel. When the
power supply is switched on, the indicator on the switch and the indicator next to the button
(A) on the top panel will light up and an audible 'beep' will be heard. The main switch also
activates cooling fans located in the power supply and in the lamphouse.
2.
When the power supply is switched on, the unit automatically starts on 'standby' mode, as
indicated by the light next to the button (A) on the front panel. In order to activate the power
supply, depress the button (A) a single time. The indicator light will turn off and a single 'beep'
will be heard. The power supply is now ready to operate.
3.
To switch on the main (coaxial) light, press the button (C) on the top panel. To switch on the
auxiliary light, press the button (B) on the top panel.
4.
The intensity of the main and auxiliary light may be varied by selecting the up or down arrow
intensity selection button (D) on the top panel. There are five intensity settings. In the event
that the power supply is switched off or placed on standby, the intensity will revert to the
previous setting when the power supply is switched back on.
5.
A 12V battery may be connected to the power supply as a backup for mains or as an
alternative to the mains supply. To connect a battery, place the crocodile clips on the battery
cable to the appropriate terminals on the battery (red positive +, black negative -) and connect
the battery cable to the panel plug (G) on the front panel.
6.
The foot control may be connected to the front panel by inserting the plug on the end of the
foot control cable into the socket (I) on the front panel. When a pedal on the foot control is
depressed, the indicator (J) on the front panel will light up. This indicates that the foot control
is connected and working properly. To increase the speed of the power focus and zoom
which are activated by the foot controls, turn the speed control (K) on the front panel in the
anticlockwise direction. To decrease the speed of the power focus and zoom, turn the knob
clockwise.
7.
In the event that the power supply fails due to a supply variation, the power supply can be
reactivated with the resettable circuit breakers (F) and (H) on the front panel of the power
supply.
LAMPHOUSE
1.
The lamphouse on the SO-5000 ophthalmic microscope produces a coaxial light which
provides a red fundus reflex from the back of the eye. The intensity of the light may be
controlled from the top panel of the power supply or by using the optional foot controls.
2.
The lamphouse position may be adjusted if the light patch is not exactly centred on the centre
of the image viewed through the eyepieces. To centre the light patch, adjust the angle of the
lamphouse by turning the socket screws (using the socket key provided in the tool box) in the
plate fixed to the microscope holder. When winding the socket screw in on one side, wind the
socket screw on the other side an equivalent amount in the opposite direction to ensure that
the lamphouse is held firmly in place. A small amount of adjustment of the two screws should
be sufficient to adequately centre the light patch.
