The 32-channel electro-prospecting device " Electrotest-32Rm / bt "(hereinafter, the device "Electrotesit-32Rrm/bt") is a development, continuation of the line of previously developed devices "Electrotest-RM" and "Electrotest-2Rm". Modernization of the device "Eletrotest-2Rm" with the installation of a Bluetooth module and the use of new circuit solutions, element base allowed to create a multi-channel version of the device. The presence of a multi-channel input expands the capabilities of the device and allows you to apply the measurement methods used in tomography. In addition, it increases labor productivity.

The device "Electrotest-32Rm / bt" consists of two functionally complete blocks. The first is the device "Electrotest-2Rm / bt" and the second is a 32-channel switching and measuring unit (SMU). The connection between them is via Bluetooth, i.e. there are no communication cables. Both units (devices) have built-in batteries and external network charging units-automatic. Control, accumulation of data during measurements, selection of modes and the measurement process itself is performed using the device (unit) "Electrotest-2Rm/bt". During measurements, the generator of the device (unit) "Electrotest-2Rm/bt"is used. As an option, an external generator can be used with an output power of up to 100 W and a maximum output voltage of up to 500 volts.

Communication and control of an external generator via Bluetooth with the device "Electrotest-2Rm / bt".

The device "Electrotest-32Rm / bt" is designed for measurements by various methods:

electric profiling , vertical electrical sensing, natural field, as well as for measuring the intensity of stray currents, electrotomography.

The parameters of the device "Electrotest-2Rm / bt"in this version ("Electrotest-32Rm/bt"), as a unit, are similar to the parameters of the device" Electrotest-2Rm/bt" except that its software ("firmware") has been changed and supplemented.

The appearance of the device " Electrotest-2Rm / bt " as a block in the device" Electrotest-32Rm/bt "does not differ from the standalone device"Electrotest-2Rm/bt". The switching and measuring unit (CIB) is assembled in a shock-resistant plastic case, which allows it to be used in field conditions and protect it from dust and moisture, mechanical damage.

Additionally. The SMU has a built-in GPS receiver, with which the operator can manually or automatically determine and record in the memory of the device (unit) "Electrotest-2Rm/bt" its (SMU) location.

The 32-channel electro-prospecting device "Electrotest-32Rm/bt" consists of the following blocks:

• block (device) "Electrotest-2Rm/bt»;
• 32-channel switching and measuring unit (SMU);
• network charger-automatic unit (device) "Elektrotest-2Rm/bt»;
