Simulating ECG Waveforms
The Analyzer is capable of generating various waveforms on the applied parts connection posts. These signals are used to test the performance characteristics of ECG monitors and ECG strip printers. See Figure 33 for proper connections between the Analyzer and an ECG monitor. For monitors using the snap style connectors, insert the BJ2ECG adapter into the connectors at the top of the Analyzer and connect the monitor leads to the snap connectors on the adapter.

To select one of the predefined waveforms, press the softkey labeled Wave Form. A scroll box with Knext to it appears above the softkey label. Use Gor Hto scroll through the different waveforms.
For all waveforms except VFIB and Triangle, the rate or frequency of the waveform is adjusted through the softkey
