The tables below provide details of the waveforms delivered by the DM7000 when connected to resistive loads of 25, 50, and 100 Ohms and set to its maximum output. The waveforms are characterized by tyDM7000al 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%.
