## What is uDL2 Config?

*** Requires a corTalk® uDLBT1 and uDL2 to use. ***
Contact us at 'sales.udl2@mobiltex.com' to purchase.

This app is for configuring the corTalk® uDL2 (micro Data Logger 2) with a uDLBT1 device. The uDL2 does not need to be plugged into a computer to set any of its settings, but still needs a computer to extract the data from the uDL2. 

The uDL2 is a high accuracy, two channel data logger designed for use with CP coupons. An integral current detector with interruption relay allow direct measurement of coupon AC current density and coupon DC current. An internal GPS receiver provides an accurate time reference and site geo-location coordinates. This app allows access to diagnostic information on the uDL2 and allows setting up the configuration to meet the customer's needs.  Note that measurement data logs, due to their size, can only be extracted from the uDL2 using the PC configuration application through the USB port.

The app allows full configuration of the uDL2 including 
- sampling interval
- input range
- enabling AC or DC sampling
- GPS
- clear memory

Other features include the
- detailed status screen for troubleshooting
- integrated manual
- clear data memory
