3.3 Harris e-Core Operation
3.3.2
With the free hand hold FTA card down and in contact with
cutting mat. This is required as the card may spin when the Harris
e-Core cutting tip makes contact with the card. Also there is a
need to hold down the card when lifting the e-Core tip from the
cored card, stripping the card off the tip.
KEEP FREE HAND AND
FINGERS AWAY FROM TARGET AREA.
3.3.3
The Harris e-Core is held above the FTA card in the vertical
position with the Harris Micro-Punch Tip perpendicular to the FTA
card target surface area.
3.3.4
Depress the red Activation Button (left side) with thumb to
begin the rotation process before making contact with the sample
surface. Lower tip until contact is made with the FTA card sample
surface. The tip is very sharp and minimal downward pressure
is needed to pass through the FTA card, making contact with the
Harris Cutting Mat below. Note: The Harris e-Core is a rotary tool.
The motor is activated by depressing the Activation Button
(red
button)
causing the razor sharp cutting tip to rotate. Rotation stops
immediately upon release of the Activation Button.
Depress the red Activation Button engaging the Harris e-Core
motor for 1 – 1.5 seconds to core the disc. Contact must be made
with the Harris Cutting Mat below the sample (card) to urge the disc
into the lumen of the Harris Micro-Punch Tip. The most efficient
and complete coring action is achieved only when the entire surface
edge of the Harris Micro-Punch Tip is in uniform contact with the
substrate surface. This will ensure that the downward pressure is
uniformly applied to the entire blade/sample surface interface.
3.3.1
Grip Harris e-Core unit in either hand. Use wrist strap to
optionally position excess cord along wrist (far left) or position cord
as shown in the illustration on the immediate left to keep cord out
of sampling zone.
