When sending a data logger for calibration to Vaisala, you do not need to remove the data logger from the logger holder.
DL4000 data loggers are delivered with default factory settings. This applies both to the factory-installed data loggers and the ones delivered as spare parts. For instructions on configuring measurement units and scaling in the data loggers, see the Vaisala viewLinc Enterprise Server User Guide for your viewLinc version, available at www.vaisala.com/viewlinc.
