A.5 Data Logger
Data log files can be deleted from the flowmeter’s memory or transferred from the
flowmeter to a remote terminal for record keeping and analysis. In addition, if PolyLink is
run from a DDF3088, the transferred data log files can be viewed in strip chart format
(Section A.5.2).
To display the data logger screen, select
DATA LOGGER
from the VT100 screen (Figure
A-5). The number of data log files available for transfer is displayed in the top left corner
of the screen.
NOTE:
The DDF4088 and each channel of the DDF4488 have one data log file each with
approximately 10.000 data points. The DCT-6088 has one data log file with
approximately 50,000 data points. The data logger in these flowmeters is always
enabled (always recording data). When all available data points are recorded, the
data logger records over the previous data points one at a time, starting with the
oldest points first, in a continuous loop.
