Make sure that your sensor is oriented properly for your requirements. Please contact GeoSIG if you wish to change any axis direction / orientation. You might as well utilize your sensor by not fixing it to the foundation (in the case of horizontal foundations) but rather by placing it on the foundation, taking measurements and relocating for temporary or mobile measurements. - Page 6 GS_VE-1x_2x_Operation_Manual_V09.docx/14.09.2020 VE-1x/2x Series Velocity Sensor Page 6 / 10 Table 1.

(see section 3.3. Self Test) to verify the integrity of the system and installation. In precision applications we recommend a calibration audit interval of 1 year. GeoSIG can execute a calibration check, which is executed by using an accelerometer with a hardware integrator as reference velocity sensor on a shaker. - Page 10 GS_VE-1x_2x_Operation_Manual_V09.docx/14.09.2020 VE-1x/2x Series Velocity Sensor Page 10 / 10 1 Hz 1 Hz 4.5 Hz 4.5 Hz Original Additional Gain Final Signal: Characteristic Improves the low frequency 1 Hz response of Geophone response between 1 - 4.5 Hz to 315 Hz 5 Voltage to current converter (Optional-GS-320CL) 0 –...
