The present Operating Manual (OM) is the main operational document for the eddy-current magnetographing device (hereinafter referred to aas the “device” or “ECMD”) Regula 7515M used as add-in module of magneto-optical devices (MODs) for identification and detection of falsification of vehicle identification numbers (VIN) Regula 7505M.
(magnetic copying) in the superficial layers of ferromagnetic items. The device is viewed as an add-in module of Regula 7505M intended for magneto- optical visualization of VINs when carrying out forensic examinations. The device enables examination of markings on data carriers made of aluminum alloys (silumin bodies of the blocks of cylinders and reducers, manufactory’s aluminum plates, duraluminium bodies)
The obtained magnetogs of the object (VIN) stray fields are visualized by Regula 7505M under its OM. The obtained images are processed and analyzed for the following expert appraisal.

During the operation the device controller creates and sends voltage impulses with set parameters to the scanner . These parameters correspond to the type of the connected scanner and the selected operating mode . Moreover, the controller carries out self-diagnostic, controls ACC charge and provides its additional charge (if the ACC charging device is connected) .

The system of conductor tension is designed in the form of a dielectric cushion (pos. 4). An arrow (pos. 5) with a symbol indicating the type of examined material shows the direction of magnetic tape demagnetization (preliminary) and examined object scanning. The scanner is connected to the controller via the cable (pos .
