3 Overview

Measurement methods and measuring the performance of the procedure is to ensure that the basic EEG meet the clinical application of accuracy to begging. This procedure does not include the production process and electrical safety requirements.

4 metering performance requirements

4.1 Calibration voltage (amplitude internal calibrator). maximum permissible relative deviation ± 5% or ± 2μV (take large tolerance By). 4.2 Voltage measurement. the maximum permissible relative error by ± 101 U1U in % Calculated (where U1 is the voltage measurement range The minimum value, the minimum value of five times the sensitivity. For example. The minimum sensitivity of the subject EEG 1μV/mm, the The minimum value of the voltage measurement range is 5μV). 4.3 sensitivity (gain). The maximum allowable relative error of ± 5%. 4.4 Interval. maximum permissible relative error by ± 51 T1T in % Calculated (where T1 is the time interval measurement range Min Wai, equal to 0.05s). 4.5 Record Speed. Maximum allowed relative deviation of ± 5%. 4.6 Record lag. lag recording system is not greater than 0.5mm. 4.7 standard. the maximum permissible relative deviation of ± 5%. 4.8 Overshoot. not more than 10%. 4.9 Time constant. 0.03s ~ 0.1s, the maximum permissible relative error of ± 20%. Greater than 0.1s, the maximum permissible relative error of ± 40%. ......
