5.7 PALM

CapMover
The motorized PALM
®
CapMover was developed
for fast positioning with highest precision and
quick exchange of the cap for sample collection.
The LPC (LaserPressureCatapulting
pat.
) collection
device can be mounted to the PALM
®
CapMover.
This way, the cap is positioned and moved via joy-
stick to check for the catapulted specimen.

Control Apparatus
At the front of the control apparatus there are two
buttons, a joystick and an LED.
The LED essentially indicates the operational
readiness. In the event of an error or a circuit
overload, this LED will extinguish. In this case, dis-
connect the apparatus from the power supply and
ascertain the cause of the error. You should not
switch on the control apparatus until after having
done this.

Control Apparatus
Brief extinguishing of the LED also indicates a
change of speed, as well as the saving of a new
reference position.
The joystick serves to move the CapMover arm -
and consequently the cap - in two dimensions.
The buttons have the following functions:
Left button
If the button is pressed briefly, the CapMover arm
moves to the reference position that is currently
saved. By pressing the button a second time the
arm moves back to the last position it was moved
to.
If the arm has been moved from the reference
position with the joystick, then this position is
accepted as the last targeted position.
If the button is pressed for a while, then the cur-
rent position is saved as the new reference posi-
tion. The LED will extinguish briefly as a
confirmation signal.
Right button
If the button is pressed briefly, this will switch
between the 'fast' and 'slow' speed ranges. The
LED will extinguish as a confirmation signal with
each change of the speed range.
The faster speed range is suitable for examination
at a low optical magnification factor, whilst the
slower speed range is useful in the case of high
magnification.
Prolonged pressing of the button will cause the
arm to move outside of the objective area - for
example in order to take up a new cap.
Speed change, joystick and the functions of the
left button are deactivated in this position.
Renewed activation of the right button will cause
the arm to be retrieved and the cap to be moved
to the saved reference position.
5.8 Mechanical Manipulator
Instead of the PALM
®
camper the mechanical
manipulator can be used for cap movement via
hand-driven knobs.
With the mechanical manipulator you can clamp a
take-up instrument (e. g. a capillary or a metal rod
to hold conventional injection cannulae or the LPC-
instrument) and move it in the x, y or z-direction.
For more details see the manipulator manual.
