1 Introduction

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. A reference cell
input provides DC potential, AC voltage and Instant-disconnect DC potential measurements. The unit may also be
operated in dual potential mode where the potential of two structures may be measured relative to a common reference
point.
A large LCD can be used to locally verify the readings. Measurement storage capacity of 2,000,000 readings and
rechargeable battery allow the device to capture readings for over 4 months. An internal GPS receiver provides an
accurate time reference and site geo-location coordinates. 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.
This document details the configuration and operation of the uDL2 product.
