Need to Know
The Dickson Warranty
When changing logger settings (sample interval and
start date and time) the logger will automatically clear
all stored data.
To achieve longer battery life during operation, use a
less frequent sample rate and disconnect the unit from
the USB or serial port when not downloading data.
Fahrenheit/Celsius
The data logger is defaulted to log data in Fahrenheit. If
you want to view future logged data on the graph or table
in Celsius go to “File,” “Preferences” and then change the
temperature selection.
Battery Replacement
The battery level monitor on the “Setup” screen displays
the battery voltage and a low battery warning when
replacement is needed.
