MC. MILLER 400D Digital Resistance Meter

NEW: A configuration application is now available for Android™ tablets. The application is included on the CD that ships with the 400D, or if you already own a 400D, you can download the application here.

Resistance Readings with the Push of a Button. Unique, Error-free Data-logging Option.

Features
No need to select ranges or adjust dials – the Miller 400D provides a direct read-out of resistance with the push of a button
Bluetooth® interface allows optional data-logging via a Bluetooth-enabled PC (or PDA)**
Rugged, hard plastic case - safe to use on wet ground
Resistance measurement range from 0.01Ω to 10 MΩ (auto-ranging)
High resolution digital display
Resistance measurements are unaffected by any stray interference signals that may be present in the earth during readings, due to the use of narrow band-pass filters centered at 82.2 Hz (the unit's operating frequency)
Runs on a set of replaceable D-Cell Industrial Alkaline Batteries. No need to periodically recharge the unit or to plug it into a power source
Performs 10,000 single readings on a fresh set of batteries
Integrates with Universal Rectifiers' Soil Depth Selector/Multi-Pin Cable Harness System (please see Integration with Universal Rectifiers' Cable Harness)
Data-logging Capability:
The Miller 400D Resistance Meter is supplied with an "over-the pipe" soil resistivity survey program, known as ProCP Soil Resistivity, based on the 4-Pin Wenner Methodology.

Software Features & Benefits
Errors associated with writing down resistance meter readings and 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 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 is 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
