I/O module bay number 1 is reserved exclusively for the ISO Data

Logger module.

The 200,000 event data logger/electronic stripchart recorder can be

configured to match most user applications. The logger stores time-

stamped, high resolution (16-bit) data at user selected intervals

ranging from 1 to 30,000 (8.33 hours) second(s).

The module can be carried in a shirt pocket back to the office and

plugged into an RS232 serial port via the module’s integral DB-9

connector. This eliminates the requirement to carry a computer to

the installation site. The data in the logger can also be accessed

without removing the module from the flow meter. Open the door of

the flow meter and connect the 9-pin cable between the data logger

and the PC’s RS232 serial communications port.

NOTE: Not all serial ports have the same load capabilities. If the

data logger is not accessible, the problem may be inadequate power

from the serial port. In these instances an external power supply,

available from Dynasonics, is required.

The logger is capable of storing up to 200,000 measurements. The

measurements are broken into 16 locations or pages with a

maximum number of data points per location of 30,000.

If each location (page) is filled to the maximum then 6 2/3 locations

would be used.

If all 16 locations are to be used, each location could hold a

maximum of 12,500 data points.
