1.2 Overview
The Micromanipulator MUX2 has been developed for performing automized microprofile
measurements with microsensors. It consists of a compact manual micromanipulator for
the x-, y-, and z-axis, supplemented with a high-precision motorized slides (0.1 µm
resolution) for x-axis (left-right) and the z-axis (up-down). Versatile control software is
provided by PyroScience as freeware. If no computer is connected, the motorized slide
can be operated by a control knobs integrated the motor housings. For best operation
conditions, the micromanipulator MUX2 should be mounted on the Heavy Stand HS1
from PyroScience. Alternatively, it can be mounted on any flat surface providing a M6
mounting hole.

3Installation and Operation
PRECAUTION: The Micromanipulator MUX2 comprises high-precision mechanics
which can easily be damaged by improper or harsh treatment. Handle with care!
3.1 Assembly and Mounting
Please follow these steps for assembling the Micromanipulator MUX2:
1. Position the 4 mounting holes of the
micromanipulator head on top of the 4
mounting threads (red circles) in the
micromanipulator base. If the 4
mounting holes are hidden by the motor
slide, you can turn the lead screw of the
slide manually until all 4 holes are
visible as shown in the image
2. Fasten the micromanipulator head
with the 4 screws to the
micromanipulator base. The screws and
an appropriate tool are included in the
package.

3. Release the tilting screws and open the tilting
mechanism. Screw the mounting screw carefully into
the mounting nut of the Heavy Stand HS1 (if the
spring-loaded mounting nut is not exactly centred
within the groove, move it back into position with
your fingers).
4. Fasten the mounting screw.
5. Fasten the tilting screws.

6. Microsensors with diameters from 6.5 mm to 12
mm can be mounted directly to the sensor mount.
7. For mounting microsensors with diameters from
0.5 mm up to 3 mm use the included adapter for
thin microsensors. The adapter can hold two thin
microsensors simultaneously.
PRECAUTION: The motor exerts considerable forces when moving. Keep any
parts of your body (especially fingers and hairs!) out of the mechanics!

3.2 Power Supply and Manual Motor Control
1. Connect all cables as shown in the
image.
2. Ensure that the manual control knobs for both x-
and z-axis!) are in their centre positions (feel the
slight "click"!). Otherwise the motor might start
moving, when the power supply is plugged in.
3. Plug in the power supply connector. This can be
done at either motor housing (x- or z-axis). The other
motor is then powered through the data cable.

4. Choose the right mains plug
according to your country, and connect
it to the mains supply. Now the green
LED on on both motor housings of the
Micromanipulator MUX2 should light
up, indicating proper power supply.
5. Turn the control knobs in order to move
the motors for the x- or z-axis. The motor
speed is proportional to the turning angle. In
order to stop again, turn the knobs back into
its centre position. The motor will
automatically stop if it reaches either end of
the slide.
After power-up, both motor slides have to be
moved to the very top-position (z-axis) and
very left-position (x-axis). Otherwise they
cannot be moved over the full range of the
slides
.
IMPORTANT: Each time the power supply is switched off and on, the motor has
to be "homed", otherwise it will not be possible to move over the full range.
Turn the control knob counter-clockwise, and let the motor move upwards until
it stops at the upper limit. Now the motor can be moved along the full distance
of the slide.

3.3 Computer-Controlled Operation
1. Establish the power supply connections
and cabling as described in the last section.
2. Install Profix on your PC.
3. Connect the USB plug of the MUX2 to
the PC. If the Profix installation was
successful, the PC should automatically
install the correct USB-driver for the
MUX2.
4. Start Profix.
The versatile control software Profix is available by download from the PyroScience
homepage (https://www.pyroscience.com). For further instructions, please refer to the
installation guidelines and manuals of Profix.
IMPORTANT: Before connecting the USB-plug for the first time to the USB-port
of your computer, first install the control software Profix!
The installer package of Profix will install all needed USB-drivers.

4MAINTENANCE
PRECAUTION: The performance of the MUX2 depends strongly on the conditions
of its precision mechanics. Ensure that its parts are kept free from dirt, dust,
liquids and other contaminants!
Be aware, that aquariums aerated with bubble stones will deposit a fine spray
of water drops in the surrounding. Ensure that the Micromanipulator MUX2 is
shielded from this spray! Especially seawater is very aggressive, causing rapid
corrosion of metallic parts!
The mechanical performance of the Micromanipulator MUX2 depends strongly on the
condition of its precision mechanics. Periodically you might carefully clean the gear
wheels, gear racks, and the lead screw (Figure 3). For cleaning, first remove
contaminants and old grease with ethanol. Then apply a small amount of silicon based
grease to the gear wheels, gear racks, and the lead screw. In order to protect all other
parts of the MUX2 against contaminants, you might coat them thinly with a Teflon
spray.
Figure 3: The performance of the MUX2 depends strongly on the conditions of its precision
mechanics. Ensure that especially the gear racks and lead screws are kept free from dirt, dust and
other contaminants! (Image shows Micromanipulator MU1)

Under conditions with increased relative humidity it is important to avoid water
condensation in the housing of the MUX2. Condensing water might cause irreparable
damage to the electronics. Under humid conditions you should leave the power supply
connected (green LED on) even if you do not perform any measurements. That way the
motor will provide a constant heating within the housing of the MUX2, lowering the risk
of water condensation.
If you follow these guidelines, the Micromanipulator MUX2 will operate reliantly for
many years.
