1995 年 8 月，与伯明翰大学野外考古单位合作，对新版本的 RATEAU（Resistivimetre AutoTracte a Enregistrement AUtomatique）系统进行了极-极配置的现场测试。该设备由一个小型三轮车组成，内含电阻率计、电脑和电池。前轮测量沿轮廓的位置。另外两个连接到电阻率计，是金属的，并配有尖峰，确保与地面良好的电接触（电位，P 和电流，C）。两个远程电极通过长电缆连接到电阻率计。马车很轻，可以用手拉动。
在平均条件下，几天内就完成了约 3.5 公顷的大型电阻率测量。经过适当的数据处理后，地图非常详细地显示了许多有趣的特征，例如建筑物、道路和现代干扰。勘察面积为 1 ha，共 101 个 100 m 剖面，共耗时 5 h。在调查时，该原型属于最轻且最快的原型，可用于小网格间距的精确考古调查。版权所有 © 2000 约翰·威利父子有限公司
A new version of the RATEAU (Resistivimetre AutoTracte a Enregistrement AUtomatique) system in the pole–pole configuration was field tested in August 1995 on the site in co-operation with the Birmingham University Field Archaeology Unit. The device consists of a small three-wheeled carriage containing a resistivity meter, a PC and batteries. The front wheel measures the position along the profile. The two others, connected to the resistivity meter, are metallic and fitted with spikes ensuring a good electrical contact with the ground (potential, P, and current, C). Two remote electrodes are connected to the resistivity meter through a long electric cable. The carriage is light enough to be pulled by hand.
A large resistivity survey of about 3.5 ha was completed, in average conditions, in a few days. After appropriate data processing, the map shows, with great detail, many interesting features, such as buildings, roads and modern disturbances. A total of 5 h was required to survey an area of 1 ha, consisting of 101 profiles of 100 m. At the time of the survey, this prototype ranged among the lightest and the fastest available for accurate archaeological surveys with small grid spacing. Copyright © 2000 John Wiley & Sons, Ltd.
