configuration be modified. 'Parameters per record' relates to the number of parameters
from the sample cycle that are being recorded. In almost all instances. this should

the sensor table is configured to take two measurements, the data logger should be
configured to two parameters per record. If ·overwrite oldest data' is checked. and the
data logger is full, it will loop around and start overwriting the oldest data. one record at

inside. The feature wakes to the receiver to check for messages every few seconds. You
may wish to disable this feature if you are not using the data logger and instead sending
'live· data samples to a DataHub or Gateway, and/or the unit needs no re-configuration.
