M.C. Miller 44550 Digital Resistance Meter Miller 400D

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.

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
• Wireless interface allows optional data-logging via a Wireless 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 Wireless
• 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
