Logger operation
Logger comes complete with installed
battery and switched OFF. Before operation
it is necessary by means of installed user PC
software to set logging parameters and other
features. Free user program is available to
download at www.cometsystem.cz . For
communication
with
the
PC
a
communication adapter is necessary (not
included in delivery). For connection via
RS232 serial port it is necessary to use COM
ADAPTER, for connection via USB port it
is necessary to use USB ADAPTER.
Connect adapter connector to proper
computer port and plug the adapter to the
guide slots on the side of logger.
Connecting logger to the computer by means of
communication adapter
Notice:
USB connector can be located also from the computer front side
