PCS-6000 Series Motorized Patch-Clamp Micromanipulator Chapter 6: Operation
5. Holding the headstage to prevent it from slipping, loosen the headstage
pivot knob.
6. Position the approach axis angles as desired, placing the pipette under
the objective of the microscope. Carefully tighten the base pivot knob
and headstage pivot knob until the stages are locked in position.
7. Looking through the microscope objective and using the joystick and
adjustment knobs, position the pipette in the desired location. Both the
headstage pivot stage and base pivot stage provide an adjustable stop
so the approach axis can be moved, then reset back to the same angle.
This is useful when changing pipettes.
6.4. Setting the Adjustable Stop
The adjustable stop mechanism on each rotary pivot stage consists of a locking
ring, two set screws, a pin, and a brass block.
Figure 6–2 Adjustable Stop Mechanism
1. Position the headstage at the desired angle ( see previous procedure ).
2. If you have not already done so, use a .050" hex wrench to loosen the
set screws in the locking ring.
3. On the headstage pivot stage, carefully rotate the locking ring counter-
clockwise (clockwise if mounted on the left side) until the pin rests
against the brass block. With the headstage pivot stage facing you, the
pin should be resting below the brass block. Tighten the visible set
screw with the .050” hex wrench. The other set screw is covered by the
brass block; this is normal.
4. On the base pivot stage, rotate the locking ring clockwise (counter-
clockwise if mounted on the left side) until the pin rests against the brass
block. With the headstage pivot stage facing you, the pin should rest
against the brass block to the right of the base pivot knob (to the left if
mounted on the left side). Tighten the visible set screw with the .050” hex
wrench. The other set screw is covered by the brass block; this is normal.
