1. Instrument Overview 

The BDM Android screen series is an intelligent instrument that integrates data acquisition, real-time imaging, 

and multi-terminal data synchronization. It is equipped with a 10-inch (5-inch or 7-inch for single-channel) 

measurement board and 1/16/32-channel MN electrode input interfaces. After data acquisition is completed,

 this instrument can immediately check the data and generate charts.

The single-channel series uses 1-channel input measurement and is equipped with a 20-meter MN standard

 measurement cable; the 16-channel series simultaneously uses 16-channel input measurement and is 

equipped with 16-channel MN input large cables; the 32-channel series simultaneously uses 32-channel 

input measurement and is equipped with two 16-channel MN input large cables. Both support MN electrode 

and TT probe measurement modes, and can switch data superimposition filtering settings. It can be connected 

to the gold ring via MN input or wireless Bluetooth for data acquisition. The 16 or 32-channel series 

respectively support 1 - 16 channels, 1 - 32 channels, and the multi-channel simultaneous input measurement

 function, which solves the defect of field source changes in the MT method, can obtain relatively stable field

 sources, and has very good consistency in repeated measurements. Through multi-channel simultaneous input

 measurement, high-density measurement big data can be obtained, breaking through the depth limit of

 traditional high-density electrical methods, and enabling the maximum exploration depth to reach 5000 meters.

 Three or more 32-channel instruments can be used for wireless networking, forming 96-channel, 128-channel,

 256-channel and 512-channel, so as to conduct large-scale data collection, which greatly improves the accuracy 

of on-site data acquisition. The ADMT series products have obtained multiple invention patents, and since their 

launch, they have received support from the Shanghai High-Tech Transformation Project. In the past 20 years of

 practical application, we have conducted a large number of comparisons between this test and the manual 

direct current method instrument, and found that the consistency of the abnormal curves obtained by both is 

very good. In some areas with poor grounding conditions, this abnormal curve is more realistic than that shown

 by the manual direct current method instrument, and has been widely recognized and supported by customers.
