TRANSPARENT ELECTRODE: Turn intensity clockwise for HIGHER VOLTAGE
POLAROID UNIT: Turn intensity control a little bit counter-clockwise for LOWER VOLTAGE

The main concern with regard to adjusting the output voltage of the CV6000 is when one is working with a small film plate with small format film. Due to the small area that will fit on a small plate and using a small film format, like Polaroid film, the voltage needs to be adjusted lower to eliminate unwanted arcs from the subject to the edges of the film or plate. You can do this by turning the intensity adjustment counter-clockwise until very little sound comes from the unit.

Another concern is destruction of tiny objects that may be viewed or photographed, due to the very small surface area of the objects in relation to the voltage level. For example, a single seed that is energized on a plate will require a much lower voltage than a leaf. You will have to experiment to find out what the best voltage levels are for each of your specimens.

Please be aware that the harder a specimen is pressed against the plate or electrode, the dimmer the image will become, because of direct conduction of the voltage. For example, if one were to place his whole palm against the transparent electrode, he could vary the brightness of the image by either pressing harder or merely resting his hand lightly on the plate. The harder he presses, the dimmer the image will become. The same effect applies to photographing a leaf.

For Violet Ray tube use, set the intensity according to the surface area of the skin you are working with. Turn on unit only after the tube is placed against the skin, and turn it off before removing it from the skin.

The unit will produce a definite buzzing sound when it is working. If you cannot get the unit to work, perhaps the intensity adjustment is too far counter-clockwise, or too far clockwise. Also, check that the outlet the unit is plugged into is live and the correct voltage.
