## What is uDL1 Config?

*** Requires a corTalk® uDLBT1 and uDL1 to use. ***
Contact us at 'sales.udl1@mobiltex.com' to purchase.

This app is for configuring the corTalk® uDL1 (micro Data Logger 1) with a uDLBT1 device. The uDL1 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 uDL1. 

The uDL1 is a high accuracy, low cost data logger designed specifically for cathodic applications. An optional internal GPS receiver provides an accurate time reference and site geo-location coordinates. This app allows access to diagnostic information on the uDL1 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 uDL1 using the PC configuration application through the USB port.

The app allows full configuration of the uDL1 including 
- sampling interval
- input range
- enabling AC or DC sampling
- DC Wave capture (Advanced Unit Only)
- GPS  (Advanced Unit Only)
- clear memory

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