Installation
3.3.3 Sampler setup
To connect the sampler:
1. Connect the power cord to the power strip. Leave the power strip switched off.
2. Connect the supplied RS232C cable to the 9-pin connector (COM1) on the back of
the sampler.
3. Connect the other end of the RS232C cable to COM1 on the computer.
3.3.4 Mount Z-drive
Except for the Z-drive, the sampler is assembled at the factory.
To mount the Z-drive on the sampler arm:
1. Remove thumbscrews and bushings from the drive block located on the sampler arm
(
Figure 20 on page 23 ).
2. Attach the x-axis slider block on the arm tube.
3. Secure the slider block finger-tight with the 12-mm thumbscrews (installed from
the top).
3.3.5 Probe installation
To install the probe:
1. Loosen the probe knob on the probe tube slider and remove the piece of tubing
installed for shipping. Lift the probe tube slider until it stops.
Note: The tan knob will come off without the tubing or probe to hold it in place.
2. The guide slider will move to the upper position with the probe tube slider. Use the
wheel in the back of the sampler to lower both sliders until the guide slider is about
1 mm from the top. Make sure that the two sliders are in contact.
Note: Always move the sliders using the wheel at the back of the sampler to avoid crimping the
PEEK tubing.
3. Install the sample probe through both sliders, the probe knob and the opening on the
probe guide plate. Keep the sliders about 1 mm from the top. Adjust the probe so the
tip is 3 to 6 mm below the guide plate. To secure the probe, tighten the probe knob on
the probe tube slider.
4. Move the sampler arm to the rinse station (extreme left position in the standards
rack). Verify if the probe tip clears the top of the rinse station when the sampler is in
the home position.
