See the separate operatinginstructions for the Battery Charger.Warning: Battery Charger must not be located in a patient area.CALIBRATIONThe AURA PSG system includes a built-in calibration signal generator and themeans to connect this generator to the referential amplifier inputs at the first stagepreamplifier. The generator outputs a 5 Hz, 500 µV peak-to-peak square wave. Thefrequency of this source can be set by the host computer but is generally 5 Hz.Gain calibration and correction is critical to the accurate creation of montages fromthe referentially recorded data. It is recommended that a calibration procedure beperformed prior to every recording as standard practice.Calibration controls are only available in the application software. However arequest can be sent from the Base Station via a menu item to have the applicationsoftware automatically perform a calibration. Refer to the instructions forcalibrating the amplifier hardware in the TWin software manual for more details.Typically calibration involves starting the recorder software, putting the AURAPSG into calibration mode, recording a segment of the calibration signal thenconfirming the peak-to-peak value of the AC calibration signal. This data is thenused to automatically generate a list of correction values for both offset and gain.ELECTRODE IMPEDANCE TESTThe AURA PSG system includes a built-in electrode test circuit that tests theimpedance of each electrode, including the reference, for referential inputs. Thisfunction can be executed from either the application software or at the Base Stationitself. The E-TEST key on the Base Station calls this function and the results aredisplayed on the LCD, based on the preferences set in the application software. Ifthe application software is not present this function cannot be selected.Warning: The electrode impedance test should not be used withintra-cranial electrodes.
