1.3 Mechanical description
Mechanically, the Osmo1 contains four major
components (Figure 3 on page 14):
•
Sample Handling Assembly:
This module is the part of
the osmometer where testing is performed. The
sample probe, cooling assembly, and actuator switch
are monitored and controlled by the sample handling
assembly.
•
Power Supply & Control Assembly:
This component
provides power to the instrument via the fused power
inlet assembly. The Control PCB contains the logic
necessary to perform osmometer tests and manage
communications with the display assembly, printer,
and barcode scanner. The physical USB and Ethernet
ports are mounted to the power supply & controls
assembly and connected to the display assembly with
cables.
•
Display Assembly:
This assembly consists of the
display PCB and the touchscreen display. It provides
the graphical user interface (GUI) used to show and
retrieve information about tests and the instrument’s
set-up. The USB and Ethernet port interfaces and
cables are part of the display assembly.
•
Printer:
The printer generates copies of test results,
test statistics, and basic information about the
instrument, such as the serial number, date and time,
and software and fi rmware versions.
