Interpex Ix1d V350 Portable Guide
You cannot understand the Interpex IX1D v350 portable without appreciating the software. The v350 is a data collection machine; the IX1D software is the interpreter.
Interpex IX1D has been the go-to solution for VES interpretation since the 1990s. Key features include:
When paired with the v350 portable, the software can be run on-site via a ruggedized tablet or laptop. This "measure-invert-interpret" loop saves days of office work.
Here is a step-by-step look at how a professional uses the Interpex IX1D v350 portable:
Step 1: Survey Design Using the IX1D software on a laptop in the office, you design your electrode array (e.g., Schlumberger with AB/2 from 1m to 500m).
Step 2: Field Deployment You carry the v350 unit to the first sounding location. Connect four stainless steel electrodes (or a multi-core cable for roll-along). Turn on the unit. The interface shows contact resistance for each electrode.
Step 3: Data Acquisition Press "Start." The v350 automatically injects current at increasing AB spacings, measures potential (MN), and calculates apparent resistivity. It also stacks readings to reduce noise. The entire process for 20-30 spacings takes ~20 minutes.
Step 4: On-Site Inversion Connect the v350 to a ruggedized tablet running IX1D. Import the raw VES data. Run a 3-layer or 5-layer automatic inversion. Within seconds, you see a resistivity vs. depth plot.
Step 5: QC and Iteration If the inversion misfit is high, you manually adjust layers in IX1D, or re-run a specific noisy AB/2 spacing on the v350. You leave the field knowing you have good data.
The V350 is built to provide adequate accuracy for routine maintenance and troubleshooting rather than precision laboratory-grade metrology. Typical specifications include:
Actual accuracy and range depend on the exact model revision and calibration; for mission-critical measurements, users should verify specifications against the instrument’s datasheet and perform regular calibration.
A geophysicist in the field connects a Syscal Pro, measures a 10-electrode Schlumberger sounding, imports the file into IX1D v350 Portable (running from a USB stick on a Toughbook), performs automatic inversion in 5 seconds, checks the fit, adjusts layer constraints, and exports a cross-section for a client report – all without installing software on the host computer.
