In the latter case, the PDA or PC, which is in control of the Bluetooth link, commands the Miller 400D to take a reading and the resistance value is sent automatically to the PDA or PC.  \nDepending on the application, 4-Electrode, 3-Electrode or 2-Electrode, the MILLER-400D can be used to determine the following:  \n• The average earth resistivity to a specific depth (with the application of an appropriate multiplier to convert resistance to resistivity, based on the electrode separation distance)– 4-Electrode Application  \n• The resistivity of a soil sample, or of a liquid, via an electrolyte (soil/liquid) box (with the application of an appropriate multiplier to convert resistance to resistivity, depending on the box geometry)– 4-Electrode Application  \n• The resistance-to-earth of a buried electrode, such as a ground rod, or an anode, for example – 3-Electrode Application  \n• The resistance between two buried electrodes, such as two ground rods, or two anodes – 2-Electrode Application  \nThe MILLER-400D has a resistance measurement range (with automatic ranging) from 0.01Ω to 10MΩ . Over the range, 0.01Ω to 1MΩ, the specified meter accuracy is ±1.6% ±1 LS display digit ±0.01Ω and over the range, 1MΩ to 10MΩ, the specified accuracy is ±5% ±1 LS display digit. Note:  \nFor load resistances >1MΩ, in addition to internal meter errors, errors  \n11640 US Hwy 1 Sebastian, FL 32958 Tel: 1.772.794.9448 ~ Fax: 1.772.589.9072  \nE-mail: [sales@mcmiller.com](sales@mcmiller.com) ~ [Web Site:](Web Site: www.mcm","cbCaiuFC7hFvoQXU","https://ap.wps.com/l/cbCaiuFC7hFvoQXU","pdf",1497107,39,"English","# Section 1: Description\n# Section 2: How to Take Resistance Readings Manually\n# Section 3: Logging Resistance Readings on a Bluetooth-Enabled Computer (PDA, Laptop etc.)\n# Section 4: Applications\n## 4-Electrode Applications\n## Earth Resistivity Measurement\n## Soil Sample Resistivity Measurement\n## 3-Electrode Application\n## 2-Electrode Application\n# Section 5: Status Indicators and Error Codes\n# Section 6: Maintenance & Calibration\n# Appendix 1: How to Change Settings (from their default values) Using the Miller 400D Configuration Program\n# Appendix 2: How to use the ProCP Soil Resistivity Survey Program in conjunction with the Miller 400D\n# Appendix 3: Influence of test lead proximity on the accuracy of AC resistance meter readings\n# Appendix 4: Specifications","[{\"question\":\"How does the MILLER 400D measure earth resistance?\",\"answer\":\"With appropriate electrodes (pins) and test leads connected, the meter provides a direct resistance reading using a push-button operation.
