ε Dust + 

ELECTROSTATIC DUST PRINT LIFTER

Dust is more than dirt, mostly a mixture of different
things like pollen, textile fibers, dead skin cells, plant
parts, air pollutants, small particles from concrete,
plaster, asphalt and more. Dry dust on a shoe sole
gives high quality prints on floors and papers. These
prints can be lifted with Electrostatic Technique.
The electrostatic dust print lifter εDust+ is designed to
give a good result of lifting dust print from most types
of surfaces.

Safety and hazard information. Danger high voltage, only to be used by trained personnel. The unit
produces up to 12000 volts with a low current stress, but can potentially cause an electrical shock.
Do not touch the lifting film, high voltage probe or ground plate while the power is active

> Lifting prints from smaller areas

First, search the floor for footprints with oblique, low-angle light. Here we use a Versa Light Max

After you have found footprints, there may be a lot of loose debris on the floor.

To get a good print for the lifting film, you may have to remove debris that lies over the floor do that with a small blower

Cut an appropriate size sheet of lift film from the roll and place it on the found footprint with the silver side facing up.

Place the ground plate to the floor 1 – 2 cm from the lifting film edge.

Placed the εDust+ Unit on ground plate and the two ground connector to the ground plate and the High voltage, connector to the lifting film.

Switch on the high voltage and adjust to suitablelevel. Lower voltage level for stone floor and higher for wooden and plastic floor. If the red diode is not lighting, check that ground connector have contact with the ground plate and High voltage connector to lifting film. If only one ground connector has contact with the ground plate, no high voltage is produced. This function is for minimizing the risk for electrical shocks by touching the high voltage connector

Air bubbles between the lifting film and floor can easy
be reduced with the “Plastic Flattener”

Certain floor types like wood and plastic floors sometimes do not provide enough ground connection.

To increase the ground voltage and maximize the dust lifting.

Make the area of ground connection larger by using a piece of lifting film, approximately 30 x 40 cm like the picture is showing.

Place that film with the silver side facing to the floor, 3-4 cm from the lifting film and overlapping a small part of the ground plate.
Then use the εDust+ unit in the normal way

> Lifting prints from larger areas

Search the floor for prints with oblique, low-angle light. Here we use a Versa Light Max

After you have found footprints, there may be a lot of loose debris on the floor.

To get a good print for the lifting film, you may have to remove debris that lies over the floor do that with a small blower

Place the lifting film roll in suitable position on the floor for rolling out on the interesting area and rollout, at this moment, only 10-15 cm of the film with the silverside up like the picture is showing.

Place the ground plate 1-2 cm from
the sheet edge and place the εDust+ is placed with both ground connectors to the ground plate and the high voltage connector to the lifting film.

Switch on The εDust+ 

Roll out the lifting film over the floor with
high voltage on

Remove Air bubbles between the lifting film and floor can easy be reduced with the “Plastic Flattener”

> Transport and store lifted prints

To avoid electrical shock, when lifting the lifting film.
Switch off the εDust+ and make sure not hold or touch ground- or high voltage connections.

Cut of the used film of the roll.

Secure the it with tape and roll up the lifting film on a paper tube

 

Lifted dust print will not release from the lifting film other than by physical touch.

It means that you can store the film for a long time, waiting for the comparison with suspected shoes.

> Lifting prints from cardboard paper

Lifting prints from cardboard paper and similar items that have inadequate ground lead

 

Adhere a piece of the lifting film on the underside of
the cardboard, this will function as a ground connection

Connect the yellow ground cable to the yellow socket and the red high voltage probe cable to the red
socket on the unit

Connect the yellow ground cable with yellow alligator clip to the ground lifting film which is under the cardboard. Place the roll in suitable position on the cardboard for rolling out.

To avoid electric shock, when lifting the print, make sure not hold or touch the high voltage connector 
or the probe.

Switch on the high voltage and apply the electrostatic energy to the film by pointing the red high voltage probe cable to the lifting film Roll out the lifting film over cardboard and Remove Air bubbles with the “Plastic Flattener”

> Photographing lifted prints

Sometimes the quality and contrast of lifted print is not
as good because of disturbing lifted background dust.

Solving that can be very easy, try and “rinse” the lifted print by blowing with compressed air like pictures to the right showing. Make sure that no dust from the print is removed when blowing
