This is because when using the DNL920 data logger and
selecting the internal humidity sensor in the Device Setup
dialog, the internal digital temperature sensor will
automatically be selected as well. This sensor provides the
temperature compensation necessary for the humidity sensor
to reach the 3% accuracy as stated in the sensor
specifications. It is not used for recording temperature. The
internal digital sensor is used to record temperature on the
DNL920.
Custom Sensor Names
You can also give the sensor a custom name, which will
appear in the software when viewing the data. This is
convenient when using several of the same type of sensors
and you wish to differentiate between them in terms of their
environment or material it is measuring.
Recording Time
This field displays the length of time the logger memory will be
able to record for depending upon the number of sensors
used and sampling rate.
Setup and Run
Clicking
Setup and Run
will send the setup to the logger and
immediately start logging data.
Setup Only
Clicking
Setup Only
will send the setup to the logger but it will
not actually start logging data. You will need to select Run
from the Logger context menu or go back into the Setup
dialog.
