Instruction Manual
Mount a preparation disc on the TegraPol and insert a specimen

mover plate (for single specimens) into TegraForce-5.
Press the up/down key on the TegraPol to move the TegraForce

in the down position.
Adjust the distance between the disc and specimen mover plate

to about 1 - 1.5 mm.
To adjust the friction of the sideways movement of TegraForce-5
loosen the screw in the friction ring and turn the lower part of the ring
counter clockwise to increase the friction and clockwise to reduce the
friction. Make sure that you do not move the friction ring up or down
during that operation to avoid changing the distance between disc
and specimen mover plate.
There is a single electrical connection between the TegraPol and the
TegraForce-5. This provides both the 24V power supply to the
TegraForce-5 and a data bus, which enables the TegraPol and
TegraForce to communicate.
Switch off the TegraPol.

Use the single cable attached to the TegraForce-5 and connect

it to the Sample mover connector on the rear of the TegraPol. To
locate this connector, refer to the diagram for the back of the
TegraPol in the section Getting Acquainted with TegraPol.
To adjust the distance loosen the

screw in the friction ring with an Allen
key and move the ring up or down,
depending on the direction of
adjustment.
When the distance is correct tighten

the screw again to clamp the friction
ring in position.
