Gima ECG 300G Manual De Instrucciones página 152

The biological ECGs are fed into the device in form of digital signals, then the
measurement value can be obtained by calculation.
Test condition:
a) without NOISE
b)with 25uV high frequency
c) with 50uV peak to valley 50Hz/60Hz sinusoidal line frequency NOISE
d) with 1mV peak to valley 0.3Hz sinusoidal base-line NOISE
For each NOISE level above, the differences of measurements between the NOISE-free
ECGs and the ECGs with NOISE shall be determined. The two largest deviations from the mean
shall be estimated before calculation of mean and standard deviation of differences.
