Warning: Battery Charger must not be located in a patient area. CALIBRATION The AURA PSG system includes a built-in calibration signal generator and the means to connect this generator to the referential amplifier inputs at the first stage preamplifier. The generator outputs a 5 Hz, 500 µV peak-to-peak square wave. The frequency 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 from the referentially recorded data. It is recommended that a calibration procedure be performed prior to every recording as standard practice. Calibration controls are only available in the application software. However a request can be sent from the Base Station via a menu item to have the application software automatically perform a calibration. Refer to the instructions for calibrating the amplifier hardware in the TWin software manual for more details. Typically calibration involves starting the recorder software, putting the AURA PSG into calibration mode, recording a segment of the calibration signal then confirming the peak-to-peak value of the AC calibration signal. This data is then used to automatically generate a list of correction values for both offset and gain. ELECTRODE IMPEDANCE TEST The AURA PSG system includes a built-in electrode test circuit that tests the impedance of each electrode, including the reference, for referential inputs. This function can be executed from either the application software or at the Base Station itself. The E-TEST key on the Base Station calls this function and the results are displayed on the LCD, based on the preferences set in the application software. If the application software is not present this function cannot be selected. Warning: The electrode impedance test should not be used with intra-cranial electrodes.
