Description
The d4Logger is powered by 4 x D-cell batteries. 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 d4Logger is downloaded to .txt files using the free d-LOG software. One data file is created per instrument and it is named after the instrument’s digital ID. No confusion is possible between the data sets coming from different instruments, even of the same type, connected to the same logger. Further data sets are simply appended to the original data files. These can easily be imported into Microsoft Excel or any database package, and are fully compatible with YieldPoint’s free MineScope database. Wireless download can be implemented using the d-Mesh node.
