power supply. The large current is called the inrush current. The current waveform when switching on
is shown in the figure below:
Signal Settings
Touch Signal to recall signal settings dialog box:
A. Set the input voltage source
B. Set the input current source
C. Set the expected current value, the range is 100 mA
~ 500 A. The oscilloscope will set the trigger level to
expected current/20 and the vertical scale of the
current channel to expected current/3.
D. Set the maximum effective input voltage (Vrms), the
range is 1 V ~ 1 kV. The oscilloscope will set the
vertical scale of the voltage channel to maximum
input voltage/6
E. View the connection guide
F. Return to the previous menu
