Operation
5.2 Sensor data logging
The controller provides two data logs (one for each sensor) and two
event logs (one for each sensor). The data logs store the
measurement data at selected intervals. The event log stores a
variety of events that occur on the devices such as configuration
changes, alarms and warning conditions. The data logs are stored
in a packed binary format and the event logs are stored in a CSV
format. The logs can be downloaded through the digital network
port, service port or the IrDA port. DataCom (Cat. No. 59256-00 or
download from www.hach.com) is needed for downloading logs to a
computer. If the datalogging frequency is set to 15 minute intervals,
the instrument can continue to store data for approximately
six months.
