Input Impedance
To reduce the circuit load caused by the interaction of the oscilloscope and the circuit
under test, this oscilloscope provides two input impedance modes: 1 MΩ (default)
and 50 Ω.
 1 MΩ: at this point, the input impedance of the oscilloscope is very high and the
current flows into the oscilloscope from the circuit under test can be ignored.
 50 Ω: match the oscilloscope with devices whose output impedance is 50 Ω.
Press CH1  Input to set the input impedance of the oscilloscope. When “50 Ω” is
selected, the character “Ω” is displayed in the channel label at the bottom of the
screen.
Note: after the probe is automatically identified, the input impedance will be
automatically identified and you do not need to set it manually.
