Mode of operation
* If you print at a high gain setting, the waveform or calibration marks might be clipped. This clipping does not
comply with clause 51.103.1 of the IEC/EN 60601-2-51 standard. Use a lower gain setting to observe the full
waveform.
** Per AAMI EC11:1991/(R)2001 Diagnostic Electrocardiographic Devices, Section 3.1.2.1 Disclosure of cautionary
information/ performance characteristics paragraph c) Accuracy of input signal reproduction, the manufacturer
shall disclose the methods used to establish overall system error and frequency response. Welch Allyn has used
methods A & D, as prescribed in section 3.2.7.2 and 4.2.7.2 of this same standard, to verify overall system error
and frequency response. Because of the sampling characteristics and the asynchronism between sample rate and
signal rate, digital ECG systems such as the CP 50 may produce a noticeable modulating effect from one cycle to
the next, particularly in pediatric recordings. This phenomenon is not physiologic.
*** Disposable electrodes from Welch Allyn shall be used during patient defibrillation.
