The d1Logger’s is powered by a 9V battery. It automatically enters into sleep mode between measurements so that the battery can last up to 1 year when taking 3 readings/day. Even then if battery power is lost the data stored will be retained. 32Mb of Flash memory will collect 10,000 readings with up to 10 channels. A 3V coin cell battery is used to maintain power to the on-board real-time clock.

Data from the d1Logger is output to .txt files using the free d-LOG software. A single data file is created and it is named after the instrument’s digital ID. It can easily be imported into Microsoft Excel or any database package, and is fully compatible with YieldPoint’s free MineScope database.
