Indicators/Displays.
During the course of the inspection, confirm the operation of all lights, indicators, meters, and visual displays on the monitor and the charger (if appropriate). For units with an ECG monitor, observe a simulated ECG signal on the display, and verify compliance with the following criteria: The baseline should be flat and without 50/60 Hz interference or other noise with the ECG simulator attached.
All portions of a simulated ECG waveform should be clear and visible, including the P-wave and QRS.
Ambient light should not affect the visibility of the trace. ( If monitor reflects ambient light, making the ECG difficult to see, try adjusting the display brightness and/or contrast.)
For units with pacing capabilities, connect the monitoring leads to an E4CG simulator or pacemaker analyzer. Connect the pacing cable to an appropriate test load or a pacemaker analyzer, start the pacemaker, and print a strip. Verify that the pacing maker rate varies as the pacing rate control is adjusted.
