Data Acquisition Tests
ECG Functions 1. Connect the MEI Multifunction Microsimulator, pn MARQ1, and
appropriate patient cables, to the ECG connector of the monitor.
Turn the monitor and the patient simulator on.
2. Set the monitor to display leads I, II, and III and a second time to I,
II and V:
¥ Select WAVEFORMS ON/OFF from the menu.
¥ Set the displayed waveforms for the following ECG leads:
3. Set the patient simulator to output calibration (cal) pulses at 1.0 mV.
4. Check the cal pulse () amplitude. These should be according to the
printed graph below.
5. It may be necessary to run a graph to accurately measure the cal
pulses. Perform these steps to graph all four waveforms.
¥ From the main menu, select GRAPH & ALARMS.
¥ Select GRAPH CONTROL from the menu.
¥ Set the graphed waveforms for the following ECG leads:
¥ Press the GRAPH GO/STOP front panel control on the monitor to
start and stop a manual graph.
¥ Compare the printed graph with the sample shown below.
