Datalogging & Software

Data-logging Capability

The Miller 400D Resistance Meter is supplied with an “over-the-pipe” soil resistivity survey program known as “ProCP Soil Resistivity”, which is based on the 4-Pin Wenner Method.

Software Features & Benefits

Errors associated with writing down resistance meter readings and with subsequently calculating soil resistivity values based on pin spacings are eliminated using the ProCP Soil Resistivity program in conjunction with the Miller 400D Resistance Meter.
  M. C. Miller’s ProCP Soil Resistivity application (included) can be run on “off-the-shelf” PocketPC hardware (Windows Mobile 5.0 or higher) or on a laptop PC. Hardware must be Bluetooth-enabled.
  Reading locations are represented by user-entered station numbers and readings are automatically position and data/time stamped in cases where a GPS receiver is integrated with the user’s handheld unit.
Data can be stored for up to 4 electrode (pin) spacings per reading location.Pin spacing values are user-entered in “feet” or in “meters”.
Resistance data directly acquired from the Miller 400D are converted to soil resistivity values (expressed in ohm.cm units) for each selected pin spacing value. Measured resistance and calculated resistivity values are both stored per reading.
Survey data are stored in XML files for easy reading by other applications, including ProActive, M. C. Miller’s Pipeline Integrity Data Management application. ProActive users are able to easily integrate soil resistivity survey data with other “over-the-pipe” survey data for enhanced data analysis. A conversion to XLS file format (Excel Spreadsheet) option is also included.
