Multichannel geophysical detector Operation Manual
1. Product Description
PQ-GT series multichannel natural electric field geophysical detecotr is an
intelligent instrument newly developed by our institute that integrates data
acquisition and automatic mapping. It is mainly used in geological prospecting
fields such as water prospecting, ore prospecting, and caverns prospecting.
The device can collect the potential difference data of 18 measuring points at
the same time. The collected data will be transmitted to the host, and the host
will process and save the data, and then automatically display it on the screen,
with functions such as 3D drawing effects. At the same time, it solved the
shortcoming that the natural electric field can change at any time, and obtain
relatively stable data, the retest consistency is high.
2、 Product Features
One Time Wiring: Equipped with a 10.1-inch touch screen, it can collect data
from up to 18 measuring points at the same time. After the data is collected,
the graph is automatically formed, which shortens the measurement time.
Stable and reliable: The simultaneous measurement of 18 measuring points
can effectively avoid unstable signal caused by natural electric field changes or
other interference sources, the accuracy rate is significantly improved, and the
re-measurement patterns are basically the same.

- Page 12 This method is suitable for situations where the terrain is relatively open and flat, there is no obvious valley reference and judgment on the ground, and the direction of the underground structure cannot be judged intuitively. Parallel wiring can be used to explore the underground structure broken zone. Cross Wiring One t is suitable for situations where underground faults or fissures develop along the direction of valley extension.
