ADZN300 Ground water DetectorUser Asked Questions Analysis

This FAQ is compiled from questions raised by International users via the WhatsApp group "AIDU After-sales Service ADZN300" and responses from our engineering team.

Q1: Which APP should be used with ADZN300? Can I use AIDU PROSPECTION?

A:

ADZN300 can ONLY use the AIDU WATER APP for measurement. AIDU PROSPECTION is NOT supported.

Although AIDU PROSPECTION offers more intuitive data interpretation (including 3D visualization), the ADZN300 hardware and firmware are specifically designed to work with AIDU WATER. The two applications use different APIs and data protocols. If you attempt to install AIDU PROSPECTION on ADZN300, you will be unable to obtain the verification code or complete measurements properly.

Recommendation: Always use the latest stable version of AIDU WATER (or the specific version recommended by our engineers, such as v7.1.52).

Q2: Why do ADZN300 measurement results differ from my other devices (SX300 / ZN180)?

A:

Although ADZN300, SX300, and ZN180 are all natural electric field groundwater detectors, even using the same model to repeatedly measure the same survey line will not yield identical results. The reasons are:

1. The natural electric field signal is inherently dynamic and fluctuates over time.

2. Different models have different sensor precision, signal processing algorithms, and filtering methods.

3. Focus on identifying the spatial position and morphology of the same low-resistivity anomaly across survey lines, rather than absolute numerical consistency at single points.

Recommendation: Combine the measurement results with local hydro-geological conditions (lithology, precipitation, nearby well depths, historical drilling data, etc.) for comprehensive analysis to improve accuracy.

Q3: What do the colors in the measurement map represent?

A:

The instrument measures apparent resistivity. Different colors represent the electrical conductivity of subsurface materials:

● Red / Warm colors (High-resistivity zone): Represents subsurface structures that do not conduct electricity easily, such as hard bedrock, dikes, dry soil, etc.

● Blue-purple / Cool colors (Low-resistivity zone): Represents electrically conductive subsurface layers, such as aquifers, moist loose soil, clay layers, etc.

In practice, focus on finding continuous and stable low-resistivity anomalies along the survey line, and evaluate whether they represent potential aquifers based on geological background.

Q4: When using default parameters, resistivity values keep increasing with depth. Is this normal?

A:

This is a normal characteristic of the default parameter algorithm. In areas without obvious anomalous electrical layers, the maximum apparent resistivity calculated by the default algorithm will increase with depth.

If you believe this parameter does not match the geological conditions of your survey area, you can select "Parameter 0" in the data processing interface and then redraw the result map. Parameter 0 uses a different calculation algorithm that may better reflect your local geological conditions.

Note: Not all areas require switching to Parameter 0. If the default parameters already clearly reveal low-resistivity anomalies, no adjustment is needed.

Q5: The latest AIDU WATER version does not have the "Parameter 0" option. What should I do?

A:

Some newer versions of the AIDU WATER APP may have removed or hidden the Parameter 0 option, displaying only "Default" parameters.

If this occurs, please install the older version recommended by our engineers (such as v7.1.52), which retains the Parameter 0 option. Contact our after-sales team to obtain the installation package.

Q6: There are few low-resistivity reaction zones in the results. How do I determine if drilling is suitable?

A:

Few low-resistivity zones may indicate unfavorable groundwater occurrence conditions in the survey area, or that the survey line layout did not effectively cross water-bearing structures.

Recommendations:

1. Combine actual hydro-geological information (water yield of nearby wells, aquifer depth, lithology, etc.) to comprehensively evaluate drilling feasibility.

2. Try adjusting the survey line direction and position, increasing point density, and re-layout the survey grid.

3. If multiple survey lines consistently show weak low-resistivity anomalies, the area may indeed be unsuitable for drilling. Consider relocating the survey area.

Q7: How should measurement parameters be configured? What do stacking times and resolution mean?

A:

In the AIDU WATER "Instrument Setup" interface, the two main parameters to note are:

1. Stacking Times (Nombre de superpositions)

   - Meaning: The number of repeated measurements during data acquisition. Higher values suppress noise more effectively and yield more accurate results.

   - Trade-off: Higher stacking times significantly increase measurement duration per point.

  - Recommendation: The default value of 5 is sufficient for most scenarios.

2. Resolution (Résolution)

   - Meaning: Lower values indicate finer data acquisition granularity and higher precision.

  - Recommendation: Use the default setting; manual adjustment is generally unnecessary.

Q8: The sensor makes noise during measurement. Is this normal?

A:

Slight, regular noise from the sensor during measurement is usually a normal phenomenon caused by electromagnetic coil operation.

However, if you observe any of the following, please contact our after-sales engineers promptly:

1. Unusually loud, sharp, or irregular noise.

2. Significant data jumps or anomalies accompanying the noise.

3. Poor repeatability when measuring the same location multiple times.

Best practice: Record a video of the measurement process (including audio) and send it to our engineers for assessment, enabling rapid problem diagnosis.
