Waveform Details:

The tables below provide details of the waveforms delivered by the YS-MD7000 when connected to resistive loads of 25, 50, and 100 Ohms and set to its maximum output. The waveforms are characterized by ty YS-MD7000 al 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%.
