Data logging
§
The controller is capable of storing up to 50,000 readings per probe .
The factory setting for the sample rate is every 15 minutes, which will
provide enough storage for 520 days . The sample rate can be change
to provide data logging for a longer or shorter time interval by changing
the
Sample Rate (Min) in the advanced settings menu . 0 = off and
360 minutes maximum .
Data Storage
§ Data can be captured different ways . The factory default is for the data
to overwrite itself when the memory is full . This can be changed in the
advanced setting under
Data storage overwrite . When this parameter
is set to No, the system will display an alert when the memory is 75%
full . To clear the alert the data must be downloaded .
Data duration alarm
§ A reminder can be set to download the data in the
Data duration alarm
in the advanced setting . The data duration can be set from
1 to 180
days . If the data duration alarm is used, then the Alarm on data full
parameter in the advanced setting must also be set to
Yes .
