2 Diogen 24/24 Two-regime seismograph "Diogen-24/24" delivers high-quality seismic data to accurately assess geological conditions within engineering and exploration. Besides the seismograph "Diogen- 24/24" allows to work in a seismological mode - the earthquake monitoring.

4 Diogen 24/24 seismograph connection scheme

5 Diogen 24/24 software possibilities Part 1 Software is divided on 2 parts: engineer and seismologic. The program for an engineering mode: Changing Sample Interval(from 0.025ms to 5ms) Number of readout up to values Recording delay Sonar mode (adding and recording virtual channels) Different normalize modes Spectrum forming Graphic noise monitor SEG-Y support Hodograph construction Advanced editing of stacking

6 Diogen 24/24 software possibilities Part 2 The program for an engineering mode: Sample Interval (0.5ms, 1ms, 2ms, 5ms) Unlimited recording Simultaneous recording of all 24 channels Sensitivity of channels changing Record is produced in own binary format, so there is a tool to convert from our format to text format

7 Engineer program Main window Tabs Recorded or opened Seismogram Stacking Window Main panel Normalize modes Controls to manipulate with amplitude and width of the seismogram traces

8 Main panel Record manipulating elements: Start begin recording Test start to record in test mode Reset clearing last stack Delete deleting all recorded information Stacking Sample Interval Counting number of digits in record Rec.len. Record length Delay time delay after which record begins Start level sensitivity of the start up gephone Mode record mode combo box (Engineer and Sonar mode) Stacking quick panel: Stacking with + and - ; number of stacking ; removing last stack and adding back removed one Open graphic noise monitor The battery charge level

9 Graphic noise monitor Test generator is need to detect problems with geophones Analog filters All channels sensitivity changer Channels sensitivity Channels inverting Channels fixing: If channel fixed then it did not involved in process of stacking

10 Hodograph construction There is an easy and intuitive way to construct hodographs on just recoded image, and save them in text or Excel format.

11 Sonar mode Sonar mode is recording mode, using it you can add (virtual) channels to just made record. The seismograph has 24 channels, but if you want to see more traces (then 24) on one seismogram, you can move cable next position, select add traces in Sonar mode and proceed the registration.

12 Spectra To make fft of signal and see it spectra user can press the spectra button in interpretation sub menu

13 Normalize modes and rotation of view Part 1 There are two types of normalization: By max one program finds trace with maximal self amplitude and calc amplitudes of other traces in correspondence of maximal one

14 Normalize modes and rotation of view Part 2 By all program finds maximum values in each trace and accepted them equal to unit. Then program calc traces in correspondence of their normalized maximum values.

15 Normalize modes and rotation of view Part 3 Rotation. Program can rotate seismogram on 90 degrees. So, there is two types of seismogram view: horizontal and vertical.

16 Stacking Program can make stacking with addition and subtraction, also in half automatic mode (you can change + on - or on the contrary between stacking). As there Is stacking window in program, in this window operator can add or subtract any necessary stacking.

17 Seismologic program Main window Start and Stop record Sample Interval Archive window Channels parameters

18 Seismologic registration Seismologic Archive window shows Data with very small delay while in main window data shows faster. Also you can see all recorded files in archive window.
