Set flow rate
The contact pressure of the tubing cartridge must be adjusted in order to
regulate the flow rate. Proceed as follows:
Set the contact pressure
￭ Fully loosen the contact pressure lever (7-5), i.e. press it all the
1
way down.
￭ Switch on the peristaltic pump.
￭ Raise the contact pressure lever one step at a time until liquid
flows.
￭ When liquid starts flowing, raise the contact pressure lever by an
additional 2 ratchet increments.

The contact pressure is now set optimally.
The delivery rate depends not only on the correct contact pressure
but also on the interior diameter of the pump tubing and the rotational speed of the drive.

Caution
Switch the instrument off before connecting or disconnecting a USB
device or a USB stick.
The 863 Compact Autosampler can only recognize the device immediately after switching on.
The following devices can be operated directly on the USB connector
with the 6.2151.100 adapter:
￭ USB sticks (for the backup or storing of methods)
￭ 6.2147.000 numerical USB keypad
￭ USB hub (with or without an own power supply)
The 6.2147.000 numerical USB keypad serves for comfortable numerical input and for navigating in the dialog. In addition, it provides two USB
connectors. Connect additional USB devices to the keypad.
Note
Most of the USB devices need a so-called hub in order to work correctly.
A USB hub is a distributor to which several USB devices can be connected. USB hubs are available in specialty stores in a number of different
models.
The USB (OTG) connector of the 863 Compact Autosampler has no
such hub. The 6.2147.000 numerical USB keypad has a USB hub and
two USB connectors.
