一、簡介
The PQWT-TC150 is a professional instrument designed for underground water detection, primarily utilized by well drillers, drilling companies, and geologists. It employs the natural electric field as an electromagnetic field work source, measuring differences in resistivity of underground rock, mineral, or groundwater. This method accurately locates the position and depth of groundwater, with a maximum detection depth of 150 meters. The instrument automatically generates curve and profile maps after data collection, aiding in the quick determination of optimal drilling locations and depths.

4. 設定
Follow these steps for initial setup of your PQWT-TC150 device:
- 接線：
- Select a measuring tape of 50-100m.
- Lay out the tape along the intended measurement line.
- Mark the start point. Geophysical prospecting should be perpendicular to the tectonic line.
- Plug one electrode near the host machine at the 0m mark on the tape.
- Plug the other electrode at the 10m mark on the tape.
- 開機：
- Long press the power button on the host machine to enter the startup interface.
- The display will show six options: Single Frequency, Three Frequency, Profile 民意調查， File Explorer, Settings, and Service.

5. 操作說明
The PQWT-TC150 offers various measurement modes to suit different geological conditions and exploration needs.
5.1 測量模式
- Single Frequency: Used for basic machine testing to ensure normal or abnormal working conditions. Recommended for dry land or stone surfaces before point measurement.
- Three Frequency: General testing for large areas to identify potential drilling positions. Helps in finding abnormal points of high or low value.
- 專業版file 民意調查： For accurate measurement and finding underground water. This method is detailed below.
5.2 專業版file Survey Operation
To perform a Profile Survey measurement:
- 從主介面選擇“專業版”file “測量”進入測量介面。
- Before recording, ensure the two connected electrodes are placed in a crossing manner.
- Click "Line Test" on the instrument. A green light indicates the line is normal.
- Adopt a 10-meter electrode distance for measurement.
- Plug the electrode near the host machine into the ground at the 0m mark on the scale.
- Plug the electrode at the other end into the ground at the 10m mark on the scale.
- Plug in the electrode rod to select the measuring line.
- Click "Record" to begin data collection. The instrument will emit a reminder sound upon completion.
- Move both electrodes forward by one meter and repeat the recording process. Continue this for all desired measurement points along the line.
- After one measuring line is finished, the curve graph will be displayed automatically. Click "Profile「 到 view 親file 地圖。
- The picture can be zoomed in or out using the "+" or "-" buttons based on requirements.
5.3 重要考慮因素
- The electrode rod should not shake during samp林志玲。
- Avoid contact with metal objects on the ground during samp林志玲。
- It is suggested to test over 15 points for one measuring line to ensure comprehensive data.
- It is forbidden to use the instrument in thunderstorm weather.
- Avoid regions with high-pressure lines or significant ground drops.
5.4 數據解讀
The instrument generates profile maps and curves to visualize underground resistivity. These maps help identify potential water sources:
- 專業版file 地圖： Displays horizontal measurement points and vertical detection depth. Resistivity values are color-coded (e.g., blue for low resistivity indicating water/mud, yellow for middle resistivity indicating rock, red for high resistivity indicating caves).
- 曲線： Regular sudden changes in the curve (e.g., "V" type, "W" type, "L" type, "A" type) indicate geological structures like faults, fissures, or intersections of lithologies where water retention is likely.
