Data Logger

Configuration

NOTE: The logger will not automatically go to the next location if

the previous location is filled. In this case when the location exceeds

30,000 data points the oldest points will be discarded in favor of new

points. This is the classic FIFO memory stack.

Up to 16 separate logging sessions are possible with up to 12,500

points each but for each new measurement session the logger must

be stopped, a new page selected using the keypad or data logger

utility, and then the logging must be started again. Similarly if a

single data acquisition session were to exceed 30,000 points the

logger must be stopped, a new location selected using the keypad

or data logger utility, and then the logging must be started again.

NOTE: The data logger is not accessible using the TFX’s infrared

adapter. Communications between the data logger and computer

must be established using a directly connected RS232C or RS485

connection.

NOTE: If the data logger is accessed during a logging session the

logger will stop logging as soon as the data retrieval is started. The

logger must be started again when the retrieval process is complete.

NOTE: The flow meter must be on to supply power to the data

logger if information is to be retrieved while the logger is still

installed.
