Click the CH1 channel status label to open the setting menu of CH1. Then, click
Impedance continuously to select the input impedance of the oscilloscope. If you
select "50 Ω", the channel status label at the bottom of the screen will display the

.
Note:
âš« After the oscilloscope recognizes the probe automatically, the input impedance
will also be auto recognized. You do not have to set it manually.
âš« The setting of the input impedance will affect the ranges of channel vertical
scale and offset.
Waveform Invert
Click the CH1 channel status label to open the setting menu of CH1. Then, click
Invert continuously to enable or disable the waveform invert. When enabled, the
channel label is displayed, as shown in the following figure.
When disabled, the waveform is displayed normally; when enabled, the voltage
values of the displayed waveform are inverted (as shown in Figure 2-1). Enabling the
waveform invert will also change the result of math function and waveform
measurement.
(a) "Invert" Off
(b) "Invert" On

Note: When the waveform invert is enabled, the trigger edge or the trigger polarity
will change (e.g. Edge trigger, Pulse trigger, or Slope trigger).
