WSS-DM7000 Biphasic Automatic AED Defibrillator Monitor
The tables below provide details of the waveforms delivered by the WSS-DM7000 when connected to resistive loads of 25, 50, and 100 Ohms and set to its maximum output. The waveforms are characterized by tyal values for peak current (Ip), and for monophasic: duration of the output phase (t) or for biphasic: duration of the first output phase (tphase1), and duration of the second output phase (tphase2). The values shown are within 10%.
