Semi-micro Calorimeter Instruction Manual

Bar Code Port
The use of barcodes in the laboratory has become a highly accurate, rapid and
inexpensive way to identify samples. When purchasing this feature, the user must
supply Parr with the MAC address of the calorimeter (found in the Software & Hardware
Info menu screen). This allows Parr to activate the feature key. In order to enable the
calorimeter to use the bar code feature, the feature key needs to be entered into the
instrument. Select the “Program Information and Control” key from the Main Menu.
Next, select “Feature Key” and enter the feature key purchased from Parr Instrument
Company into the instrument by using the touchpad. Pressing the key labeled “ABC”
allows the user to switch from upper case letters, to lower case letters and finally to
numerals. A CD containing all the necessary documentation and setup information for
using both the scanner and the printer is provided at the time of purchase. A PC based
program used for printing bar coded labels is also provided on this CD.
Computer Connections
If the 6772 Calorimetric Thermometer is
to be connected to a computer, the
Ethernet connection should be used.
Calorimetric Thermometer test data can
be transferred to an Ethernet network
connected computer using the FTP File
Transfer Protocol. First, you must know
the IP address of the network-
connected Calorimetric Thermometer.
The network DHCP (Dynamic Host
Configuration Protocol) server provides
this address shortly after the
Calorimetric Thermometer is turned on.
The address can be seen on the
Software & Hardware Info” screen, under Program Info and Control Menu; see the
example screenshot. Users who don’t have a network infrastructure can create a simple
network by connecting a router with DHCP server capability to the Calorimetric
Thermometer using an ordinary CAT 5 network cable. The Calorimetric Thermometer
should be connected to LAN side of the router. The PC in turn is also connected to the
LAN side of the router using a similar CAT 5 cable. A D-Link 614+ router is
recommended for this purpose. For this router, operated without a WAN connection, the
primary DNS address of the router (WAN setup) must be set to the IP address of the
router found on the LAN setup page. Other routers behave differently in the absence of
a WAN connection. Providing an active upstream connection to the WAN port of most
routers generally minimizes the use of any obscure setup configurations. An FTP
enabled web browser can be used to access stored test data. The URL is of the
following form:
ftp://root:[email protected]/../flash/data/
In this case, 192.168.0.125 is the IP address of the Calorimetric Thermometer.
