Introduction
The uDL1 is a high accuracy, low cost data logger designed specifically for cathodic applications. The device is very
simple to use and has a large LCD that can locally verify the readings. Two models of the uDL1 are available. The
Basic model has a 500,000 readings measurement memory with a configurable sample rate between 1 second and 12
hours. The Advanced model has a 1,000,000 (2,000,000 for G2 hardware revision) readings measurement memory,
internal GPS receiver, and a DC voltage waveform capture mode which samples at rate of 10 times per second. A long
life rechargeable battery allows the device to operate for 6 months or capture 1,000,000 readings per battery charge. The
internal GPS receiver in the Advanced model provides an accurate time reference and site geo-location coordinates.
Both the Basic and Advanced models are capable of measuring DC volts, AC volts and internal temperature. The small
physical size and water resistant (non-submersible) enclosure allow the device to be utilized in a wide range of field
environments including within common CP test stations. The generation 2 (G2) advanced model also supports
interruption waveform tracking for impressed current cathodic protection close interval survey use.
This document details the configuration and operation of the uDL1 product.
